1 OVERVIEW
The 9109-22 power supply system provides an intrinsically safe field network for Foundation™
fieldbus systems in hazardous areas. It is intended for use with control systems equipped with H1
interface cards that must draw current from the host fieldbus segment in order to operate. Such
systems include:
• Emerson DeltaV
• Honeywell Experion-PKS with 4-link Fieldbus Interface Module.
Versions of the 910x-22 Series power supply are also available for use with other control systems.
Visit www.mtl-inst.com for more information.
The output of the power supply modules complies with the Fieldbus Intrinsically Safe Concept
(FISCO) model, in accordance with IEC standard 60079-27. The key advantages of FISCO over
earlier ‘Entity’ model installations to FF-816 are higher available field current and reduced safety
documentation, while retaining the ability to conduct maintenance while energised and without
‘gas clearance’.
The 9109-22 system builds on the MTL 912 x-IS range of power supplies, which have become
established as the industry standard solution for FISCO networks. The system now achieves higher
levels of overall system availability by providing redundancy of the power modules.
When used with intrinsically safe versions of MTL-Relcom Megablock field wiring hubs, the power
supply system allows complete FISCO networks to be assembled for even the most demanding
process applications.
The datasheet for this model is referenced on the opposite page.
2 DESCRIPTION
2.1 Architecture
Each IS fieldbus segment is powered by a redundant pair of pluggable FISCO power supply
modules. The modules operate in active/hot standby mode, ensuring that the fieldbus segments are
continually powered.
In the event of a failure of an active power supply module, the field circuit is automatically transferred
to the standby module. The change-over is managed by Supply Arbitration Modules (SAMs), which
monitor the health of the FISCO power supplies while maintaining intrinsic safety requirements
during the transition to the standby module. The SAMs are also duplicated and replaceable,
meaning that there are no non-redundant system components.
Switch-over is achieved rapidly and in accordance with Foundation™ fieldbus specifications,
and without risk of losing fieldbus devices from the bus. A combination of LED diagnostics and
alarm signalling provides failure notification of FISCO power supplies, SAMs and host power
modules, allowing failed hardware to be identified and full redundancy to be restored by module
replacement.

2.2 Module carrier
The module carrier provides fieldbus power for four fieldbus segments. It supports pluggable power
supply and arbitration modules for each segment and all connection facilities.
Each carrier has pluggable screw terminal connections for redundant 24V input power and for the
intrinsically safe field trunks. Fixed screw terminals are provided for each of the fieldbus segments for
connections to the host H1 terminals on the fieldbus control system. A volt-free failure alarm is also
provided for connection to a digital input module. There are no active electronic circuits on the carrier,
resulting in long calculated Mean Time To Failure (MTTF) and overall high system availability.
The carrier dimensions are designed to provide high packing density in typical 800mm wide
equipment cabinets. Survival in high-vibration marine environments is achieved by secure panel-
mount fixings.
The FISCO power supply modules are pluggable versions of the MTL 9122-IS range, and support
the same level of features. LED indicators provide information on system health and assist with fault
diagnosis.
2.3 Redundant host power
The H1 interface card, in some host control systems, draws a small quiescent current from each
host segment. The 9109-22 power supply system is therefore equipped with redundant, pluggable
9126-PU power supply modules that provide up to 30mA for each of the four segments. These
modules are also duplicated and replaceable. Failure of either 9126-PU module is also signalled
via the volt-free alarm terminals on the module carrier.
3 INSTALLATION
WARNING: This equipment must be installed, operated and maintained only by trained competent
personnel and in accordance with all appropriate international, national and local standard
codes of practice and site regulation for intrinsically safe apparatus and in accordance with the
instructions contained here.
3.1 General
The 9109-22 power system is designed for mounting in a non-hazardous area.
The mounting conditions must:
a. prevent any form of pollution that could compromise the operation of the unit. For example, an
unpolluted location or a suitable enclosure could be chosen.
b. provide an adequate level of mechanical protection. This can be achieved by selecting a
protected location, a suitable cabinet or enclosure, or a combination of both.
c. ensure that all cable entries and connections are secure by making provision for the careful
routing and securing of all cables.
d. provide adequate security against unauthorised interference.
e. ensure that the permitted ambient temperature range of the units (–20°C to + 60°C) is not
exceeded. Power dissipation within the equipment’s cabinet or enclosure and the use of
shading against direct sunlight should be considered.
3.2 Required tools
To remove or replace any of the modules a straight-bladed screwdriver is required with a minimum
shaft length of 130mm (5¼”) and a maximum blade diameter of 5mm (3/16”).
3.3 Mounting overview
Mount the 9109-22 assembly on a vertical surface with the orientation shown in Figure 2.2. Any
other orientation will reduce the permitted maximum operating temperature.
IMPORTANT: The mounting surface and any associated components must be capable of
supporting the weight of the complete assembly which is approximately 6.5kg.
Six 7mm diameter slotted holes are provided in the backplate for mounting the assembly - see
Figure 3.1 - and access to the mounting screws is provided through the circuit board (after removal
of some modules). This feature allows the assembly to be fitted to, or removed from, its mounting
without removing the mounting screws.

INM9109 Rev 2
Note: Because of the slotted mounting holes, 15mm of free space is required above the top edge
of the assembly to allow the backplate to be mounted and demounted.
3.3.1 Outdoor mounting
If the assembly is to be mounted in an outdoor location, a suitable enclosure with a minimum of IP54
ingress protection is required. However, in some locations, a higher degree of ingress protection rating is
recommended as corrosion resistance may be necessary or desirable and the emphasis should be placed
on the suitability for the application.
3.4 Surface mounting
Prepare holes in the mounting surface as shown in Figure 3.1. Thread these M6 or fit M6 captive
nuts as required.
The recommended installation method for this assembly is to use screws that have captive washers
(‘Sems’ screws) - M6 size. Alternatively, use standard M6 screws - recommended minimum length
15mm - and fit a locking washer and a plain washer on each.
Start the screws into the prepared threaded holes on the mounting surface, leaving approximately
10mm of thread visible.
With all modules removed, fit the backplate and its attached circuit board over the screw-heads (and
washers) and allow it to rest on the screws. Tighten all of the screws, to the torque recommended
by the fixings manufacturer, to secure the backplate to the mounting surface.
3.5 Mounting and removal of modules
The 9109-22 power system is installable only in a safe/non-hazardous area, so all of the modules
that mount on the carrier or adaptor board are capable of live replacement (“hot- swapping”).
Note: The SAM module has a mechanical safety interlock that prevents it from being removed
before its associated power supply; this is so that the segment power stays in a safe and predictable
state. This interlock must not be removed or defeated in any way.
3.5.1 Installing 9122-IS-CM power supply and SAM modules
The SAM module must be installed before its associated FISCO power supply module.
1. Rotate the red interlock tab on the SAM module to the side and up to reveal the fixing screw
head. See Figure 3.5.
2. Locate the SAM module in its position and tighten both of its fixing screws to a torque not
exceeding 0.9 Nm.
3. Return the interlock tab to cover the screw head. See Figure 3.5
4. Locate the FISCO power supply module to the left of the SAM module and tighten both of its
fixing screws to a torque not exceeding 0.9 Nm.
5. Repeat 1 - 4 for the other module pairs, as required.
Figure 3.5
SAM
module
interlock tab

6INM9109 Rev 2
3.5.2 Removing 9122-IS-CM power supply and SAM modules
The FISCO power supply module must be removed before its associated SAM module.
1. Loosen the two securing screws of the FISCO power supply module and remove it.
2. Slide the red interlock tab on the SAM module to the side to obtain access to the securing screw
head. See Figure 3.5.
3. Loosen the two securing screws of the SAM module and remove it also.
4. Repeat tasks 1 – 3 for the other module pairs, as required.
3.5.3 Fitting 9126-PU host power supply modules
The 9126-PU host power supply modules fit onto the adaptor board in the positions marked “HOST
POWER SUPPLY A” and “HOST POWER SUPPLY B” - see Figure 4.1 - and must be in place for
redundancy of host power to be supported.
A protective plastic cover is factory installed beside the connector for each module, and this must be
removed before attempting to fit the module. The cover has clips at each end and is easily removable
by carefully levering it off with a small screwdriver or similar impliment.
Plug the module onto the connector on the board and secure it with the two captive screws located
at each end of the module to a torque not exceeding 0.6 Nm. To remove the module, loosen the
screws and unplug the module.
4 ELECTRICAL INSTALLATION
4.1 Redundant Power Connections
Connect the incoming redundant 19.2 - 30V power supplies to the POWER A and POWER B
connectors. Correct operation requires both input power supplies to be present in order to avoid an
alarm signal being generated.
Note: Product certification requires all pluggable connectors to be in place, in order to maintain
the product’s IP20 rating (for example, see Power B in Figure 4.1).
Each input power supply must be able to support, independently - but not simultaneously, the power
requirements of four fieldbus segments; which, with a power supply voltage of 24V, require up to
2.5A when all four are running at maximum load.
The 9126-PU host power supply module(s) also require current for the host H1 cards, and this
depends upon the segments supported, the supply voltage and the host demand. For more details
on calculating the current requirements refer to the 9109-22 product datasheet.
The user can decide how many 9109-22 assemblies will be powered from each bulk supply, but
adequate protective fusing should be provided to protect both the supplies and the assemblies.
The POWER A and POWER B connectors at the top corners of the adaptor circuit board have rising
cage-clamp screw terminals and will accept connection wires of 0.14 to 2.5 mm2cross-section.
Observe the supply polarities indicated on the connectors and the circuit board. See Figure 4.1.
The screws fixing the connector to its socket should be tightened to a torque not exceeding 0.4 Nm.
4.1.1 Backplate Grounding
It is important to ensure that the backplate is in good electrical contact with the enclosure and
its protective ground. If the backplate does not obtain this ground connection directly through its
Figure 4.1
POWER B,
ALARM
and HOST
connectors

7
INM9109 Rev 2
method of mounting then a separate connection must be made from the ground terminal provided
on the backplate to the enclosure’s protective ground.
4.2 Alarm Connections
Each SAM module and each HOST PSU module contains a solid state switch that is ‘closed’ in
normal operation and in this condition exhibits a nominal resistance (@25°C) of 36W. If a SAM
module recognises a fault condition its switch will ‘open’ and present a resistance in excess of 1MW.
The eight SAM modules (two per segment) and the two HOST PSU modules are all connected in series
and the ends presented at the screw-terminal ALARM connector at the top edge of the adaptor board
(do not exceed 0.4 Nm torque). See Figure 4.1. In normal operation the ALARM terminals on the
module carrier will present a nominal resistance value of 360W - see Note 2 below.
If required, the alarm circuits of a number of 9109-22 assemblies can be daisy-chained to present
a single alarm signal. See Figure 4.2. In order to do this, any digital input module, that is used to
receive the alarm signal, must be able to recognise the total series resistance of all the carriers as
a normal ‘closed’ condition. For example, three carriers connected in series will present a series
resistance (@25°C) in the ‘closed’ condition of around 1080W.
Notes:
1. Although the Alarm terminals on the module carrier are marked ‘+’ and ‘–’ to aid identification,
the solid state alarm circuits are in fact polarity insensitive.
2. The series resistance of the solid state switches has a +ve temperature coefficient of approx 3W/°C.
3. The Alarm connector is keyed to prevent it being inserted into a Power socket on the board.
4. For the alarm circuit to operate correctly, (i.e. for the solid state switches to go to a ‘closed’
condition), all of the FISCO power supply and SAM modules, and both Host PSU modules, must
be installed on the module carrier. For any SAM module location that is not used, a blanking
module must be installed to maintain alarm circuit continuity.
4.2.1 9127-BLK blanking module
A 9127-BLK blanking module must be installed in every unused SAM location on the carrier in order
to allow the system to recognise alarms from the installed Power Supply and SAM modules. The
9127-BLK blanking module is the same size and shape as a SAM and is used to maintain alarm
circuit continuity for the installed modules.
4.3 Hazardous-Area Fieldbus Segment Connections
The intrinsically safe segment power output connections are provided via 3-way, pluggable, rising
cage clamp, screw terminals at the bottom edge of the 9109-22 module carrier. See Figure 4.3.
Note: All connector screws should be tightened to a torque not exceeding 0.4 Nm.
Prepare the cables and connect to the +, S and – terminals as indicated on the pluggable connectors.

Note: It is important during installation to segregate intrinsically safe wiring from other non-
IS wiring and to mark it clearly as intrinsically safe.
Two ground studs (IS Shield A and IS Shield B ) are provided on the module carrier, adjacent to
the hazardous area field wiring connections. These are linked to the ‘S’ terminals of the segment
connectors and provide a means of grounding the cable screens/shields of the intrinsically safe
field cables carrying the fieldbus trunks. Use them to ground the field cable shields as follows.
• Connect each of the ground studs on the module carrier to a local, high integrity earth with
a cable having a resistance of less than 1W. This should be a clean instrument earth that is
electrically bonded to the point of earthing of the local AC power supply to the equipment cabinet
that houses the FISCO power supplies. The two studs should each be wired with a separate
cable. This earth cable should typically have a cross-sectional area of 4mm2or greater.
Note: Product certification requires all pluggable connectors to be in place, in order to maintain
the product’s IP20 rating (for example, see Figure 4.3).
4.3.1 Field segment terminators
The FISCO power supply provides on terminator for each of the intrinsically-safe field segments.
A second terminator must be provided in the field for each segment, for example, by selecting
Megablock wiring hubs with built-in terminators.
4.4 Host System Connections
Host segment connectors are provided at the top of the adaptor card - see Figure 4.1. These paired
connectors, labelled Host 1A/Host 1B through to Host 4A/Host 4B, have rising cage-clamp screw
terminals and will accept connection wires of 0.14 to 2.5 mm2cross-section.
Connector screws should be tightened to a torque not exceeding 0.4 Nm.
4.4.1 Standard host connection
Connect the individual host trunks as shown in Figure 4.4.

4.4.2 Combining segments
Two FISCO Field output connections or trunks can be combined onto one host segment with each
FISCO trunk continuing to operate in fully redundant mode. This is made possible by the integration
of fieldbus repeater circuitry to the Host in the FISCO power supplies. To combine two FISCO trunks
into one host segment, connect a short cable between the Host B and the next Host A connector as
shown in Figure 4.5.

With this arrangement, the fieldbus instruments on both FISCO trunks appear logically on the
same host H1 segment. For example with 6 instruments on each of the two IS field trunks,
12 instruments appear on the ‘live-list’ of the host H1 card. This can have the benefit of maximising
the logical capacity of the host H1 card, and reducing the number of cards required for a given
I/O count. No more than two FISCO outputs may be combined on one H1 host connection, and
this can be done only if the length of the host segment is less than 30 metres (~100 ft). See section
4.4.3 for the use of Host terminators with this configuration.
4.4.3 Host segment terminators
Fixed terminators are provided for each of the four host segments on the module carrier, not in the
FISCO power supply. (This ensures that the terminator is not lost, or duplicated, when the power
supply modules are switched or removed from the carrier.)
Additional switchable terminations per segment are also provided on the carrier for use when short
cables (i.e. less than 30m) are used between the host and the 9109-22 assembly. In this case, the
second termination can be enabled (switched ON) instead of a host end termination. This method
ensures the correct impedance is presented to the host. The switches (SW1–SW4) are located
beside their associated host segment connectors - see Figure 4.6.
If two FISCO trunks are connected to a single host segement, as described in Section 4.4.2, the two
switchable terminators must be disabled (switched OFF) using the appropriate switches on the adaptor
card. The fixed host terminators on each host connector will appear in parallel, thereby providing correct
termination, provided the length of the host segment is less than 30 metres (~100 ft). No terminator
should be installed at the host H1 card.
5 TESTING AND FAULT FINDING
The 9109-22 is provided with switches and LED indicators to enable the user to understand the status
of the equipment at any time. The functionality of these diagnostic aids is described in this section.
5.1 Testing
After installation or at any other time, e.g. during maintenance checks, the output voltage at
the segment terminals should not be less than 12.6V DC. This, and many other useful fieldbus
parameters, can be measured with the MTL-Relcom FBT-6 portable tester, which also has the
advantage of being certified for use in Zone 1 hazardous area.
5.2 Manual Failover testing
Each Supply Arbitration Module (SAM) has a ‘Failover’ switch to test the
functioning of the failover mechanism from Active to Standby power supply.
This is for proof-testing of the power supply as part of a
scheduled maintenance program.
A manual changeover is caused by pressing the Failover switch on the
Active SAM. Pressing the Failover switch on the Standby SAM will have
no effect.
Failover will NOT occur if the Standby power supply, or its associated
SAM is in a ‘failed’ condition; indicated by both the Active and Standy
LEDs being extinguished, or by either of them flashing - see Section 5.3.2.
CAUTION!
Forcing a change of state of the active and standby modules by manually operating the
‘Failover’ push button is recommended only during plant shutdown, not during the operation
of a live process application.

Note: The default startup configuration always makes the ‘A’ power supply active.
To confirm the Failover action of a redundant pair - with the ‘A’ power supply active:
1. Verify the power supply is not running a live process. Follow local plant procedures
2. Verify the health of the power supply to be tested (see section 5.3)
3. Press the Failover switch on the ‘A’ SAM to force the Standby ‘B’ power supply to become the
Active one.
4. Press the Failover switch on the ‘B’ SAM to force the ‘A’ power supply to become the Active
one again.
5.3 Fault finding
The 9109-22 is provided with a number of indicators to assist the user in remedying a fault. Using
these indicators in a structured way enables the user to rapidly identify the root of the fault.
5.3.1 Incoming power supply indicators
An indicator is placed beside each incoming power supply connector (POWER A /POWER B) to
indicate whether power is present at that point.
LED label Description Healthy Status
Power A (green) Power ON (Power OK)
Power B (green) Power ON (Power OK)
A bright LED indicates a healthy input power level but a dim LED may indicate insufficient voltage.
Next, check the HOST PSU modules.
5.3.2 Host Power Module indicators
There are four LED indicators on the front panel of the 9126-PU Host Power Supply to indicate the
health of each host segment.
LED label Description Healthy Status
1 – 4 (green) Host Power 1 – 4 ON (Power OK)
A numbered indicator that does not show a light indicates a power failure on that segment. Next,
check the Supply Arbitration Module.
5.3.3 Supply Arbitration Module indicators
There are two LED indicators on the front panel of the 9129-IS SAM module to indicate the current
mode of the power supply. The description of these indicators is given in Table 5.3 below.
LED label Description Healthy Status
(Active)
Healthy Status
(Standby)
Active (yellow) Power Supply Active ON (Active) OFF (Not Active)
Standby (yellow) Power Supply Standby OFF (Not Standby) ON (Standby)
Note: During startup, either of the LEDs may flash for up to 10 seconds - this is normal operation.
5.3.4 FISCO power supply indicators
There are four LED indicators on the front panel of the 9122-IS-CM FISCO Power Supply. The
function of these indicators is provided in Table 5.4 below.
LED label Description Healthy Status
Power (green) Power ON (Power OK)
Fault (red) Fault detected OFF (No Fault)
Host (yellow) Host communications ON (Host Comms OK)
IS (yellow) Field communications ON (Field Comms OK)

5.4 Replacing failed modules
Because the 9109-22 is not installed in a hazardous area, any of the modules fitted
to the carrier may be ‘hot-swapped’ i.e. replaced without isolating or disconnecting any incoming
power supplies.
If any module failure has been identified using, for example, the fault-finding procedures described
in Section 5.3, follow the instructions provided in Section 3.5 to remove and replace the module.
It should be noted that the design prevents the removal of a SAM module without first removing its
associated FISCO power supply. Similarly, the SAM module must be installed on the carrier before
its associated FISCO power supply module.
