2 D5040 - SIL 3 Digital Output Driver G.M. International ISM0187-9
General Description: The single or dual channel Loop Powered Digital Output Isolators, D5040S and D5040D, are suitable for driving solenoid valves, visual or audible alarms to alert a
plant operator, or other process control devices in Hazardous Area from driving signals in Safe Area. They can also be used as controllable supplies to power measuring or process
control equipment.
Their use is allowed in applications requiring up to SIL 3 level (according to IEC 61508:2010 Ed. 2) in safety related systems for high risk industries. The Safety PLC or DCS driving
signals control the field devices through D5040S and D5040D, which provide isolation. For each channel two basic output circuits are selectable, with different safety parameters, to
interface the majority of devices on the market. The selection among the two output characteristics is obtained by connecting the field device to a different couple of terminal blocks.
Mounting on standard DIN-Rail or on customized Termination Boards, in Safe Area / Non Hazardous Location or in Zone 2 / Class I, Division 2 or Class I, Zone 2.
Functional Safety Management certification:G.M. International is certified by TUV to conform to IEC61508:2010 part 1 clauses 5-6
for safety related systems up to and included SIL3.

Therefore, the D5040S and D5040D modules have SIL 3 level for lifetime of 20 years.
Systematic capability is SIL 3.
Since no dangerous undetected failures have been noted during the FMEDA analysis, there is no need to perform a proof test to reveal dangerous faults which cannot be otherwise
detected.

Failure rate table:
Safety Function and Failure behavior:
D5040 is considered to be operating in Low Demand mode, as a Type A module, having Hardware Fault Tolerance (HFT) = 0.
The failure behaviour of D540S/D for NE loads is described by the following definitions :
□fail-Safe State: it is defined as the output being de-energized.
□fail Safe: failure mode that causes the module / (sub)system to go to the defined fail-safe state without a demand from the process;
□fail Dangerous: it is defined as a failure mode that does not respond to a demand from the process (i.e. being unable to go to the defined fail-safe state),
so that output remains energized; 
□fail “No Effect”: failure mode of a component that plays a part in implementing the safety function but that is neither a safe failure nor a dangerous failure.
When calculating the SFF, this failure mode is not taken into account;
□fail “Not part”: failure mode of a component which is not part of the safety function but part of the circuit diagram and is listed for completeness.
When calculating the SFF this failure mode is not taken into account.
The 2 channels of the D5040D module could be used to increase the hardware fault tolerance, needed for a higher SIL of a certain Safety Function, as they are completely independ-
ent one from each other, not containing common components. In fact, the analysis results got for D5040S (single channel) are also valid for each channel of D5040D (double channel).
Since the loop powered modules are directly supplied by the digital output of a Safety PLC, if the safety PLC imposes a shutdown state of these modules, there is no additional power
supply which can keep the D5040S and D5040D outputs energized in case of an internal fault. Therefore, all internal faults have either “no effect” on the safety function or lead to the
safe state, according to the Safety Function definitions.
Failure rate data: taken from Siemens Standard SN29500.
Description:
The D5040S (single channel) and D5040D (double channel) modules are single or double channel digital output drivers, loop powered for NE load (Normally Energized) loads.
The Safety PLC or DCS driving/control signals power the field devices through the single or double channel digital output driver D5040S or D5040D (1 or 2 intrinsic safety chan-
nels, Loop Powered), which provides the electrical isolation between Input and Output. The presence of the input loop signal is also indicated by a yellow LED on the front panel
(one for each channel).
In order to interface the majority of field devices available on the market, two basic output circuits with different safety parameters (outputs A and B) are provided for each chan-
nel. The selection among the two output characteristics is obtained by connecting the field devices to a different couple of terminal blocks.
Loop Control signals from Safety PLC Outputs are applied to Pins 1 - 2 (In. 1 - Ch. 1) and Pins 3 - 4 (In 2 - Ch.2, only for D5040D).
The Output NE loads are connected to Pins 7 - 8 or 7 - 9 (for Channel 1) and Pins 10 - 11 or 10 - 12 (for Channel 2, only for D5040D).
The following table describes the state (de-energized or energized) of each output when its control signalis in the High or Low state:

De-energize power source (turn off power supply voltage) before plug or unplug the terminal blocks when installed in Hazardous Area or unless area is known to be nonhazardous.
Warning: substitution of components may impair Intrinsic Safety and suitability for Zone 2.
Explosion Hazard: to prevent ignition of flammable or combustible atmospheres, disconnect power before servicing or unless area is known to be nonhazardous.
Failure to properly installation or use of the equipment may risk to damage the unit or severe personal injury.
The unit cannot be repaired by the end user and must be returned to the manufacturer or his authorized representative.
Any unauthorized modification must be avoided.
Warning
Operation
The single and double channel Loop Powered Digital Output Isolators, D5040S and D5040D, are suitable for driving solenoid valves, visual or audible alarms to alert a plant operator, or
other process control devices in Hazardous Area from driving signal in Safe Area. The presence of the input signal is also indicated by a yellow LED (one for each channel). They can
also be used as a controllable supply to power measuring or process control equipment.
Their use is allowed in applications requiring up to SIL 3 level (according to IEC 61508) in safety related systems for high risk industries. The Safety PLC or DCS driving signals power
The field device through the D5040S and D5040D, which provides isolation.
Two basic output circuits for each channel are selectable, with different safety parameters, to interface the majority of devices on the market. The selection among the two output
characteristics is obtained by connecting the field device to a different couple of terminal blocks.
Installation
D5040 series are digital output driver housed in a plastic enclosure suitable for installation on EN/IEC60715 TH 35 DIN-Rail, or on customized Termination Board.
D5040 series can be mounted with any orientation over the entire ambient temperature range.
Electrical connection are accommodated by polarized plug-in removable screw terminal blocks which can be plugged in/out into a powered unit without suffering or causing any damage
(for Zone 2 installations check the area to be nonhazardous before servicing). Connect only one individual conductor per each clamping point, use conductors up to 2.5 mm²
(13 AWG) and a torque value of 0.5-0.6 Nm. The wiring cables have to be proportionate in base to the current and the length of the cable.
In case of installation in zone 2, the connecting cables of non-intrinsically safe circuits must be safely routed in a cable duct or similar. The distance between the pluggable connection
terminal and the cable duct should not exceed 500 mm cable length.
In the section “Function Diagram” and enclosure side, a block diagram identifies all connections.
Identify the function and location of each on the connection terminal using the wiring diagram on the corresponding section, as an example:
Connect positive input at terminal “1” and negative input at “2” (or “3” and “4” for channel 2).
Connect positive output A for solenoid valve to terminal “7” and negative at “8” or output B to terminal “7” and negative to “9” (or “10” and “11” or “10” and “12” for channel 2).
Intrinsically Safe conductors must be identified and segregated from non I.S. and wired in accordance to the relevant national/international installation standards (e.g. EN/IEC60079-14
Electrical apparatus for explosive gas atmospheres - Part 14: Electrical installations in hazardous areas (other than mines)), make sure that conductors are well isolated from each other
and do not produce any unintentional connection.
The enclosure provides, according to EN60529, an IP20 minimum degree of protection (or similar to NEMA Standard 250 type 1). The equipment shall only be used in an area of at least
pollution degree 2, as defined in IEC 60664-1. When installed in EU Zone 2, the unit shall be installed in an enclosure that provides a minimum ingress protection of IP54 in accordance
with IEC 60079-0. When installed in a Class I, Zone 2 Hazardous Location, the unit shall be mounted in a supplemental AEx or Ex enclosure that provides a degree of protection not less
than IP54 in accordance with UL/CSA 60079-0. When installed in a Class I, Division 2 Hazardous Location, the unit shall be mounted in a supplemental enclosure that provides a degree
of protection not less than IP54. The enclosure must have a door or cover accessible only by the use of a tool. The end user is responsible to ensure that the operating temperature of
the module is not exceeded in the end use application.
Units must be protected against dirt, dust, extreme mechanical (e.g. vibration, impact and shock) and thermal stress, and casual contacts. If enclosure needs to be cleaned use only a
cloth lightly moistened by a mixture of detergent in water.
Electrostatic Hazard: to avoid electrostatic hazard, the enclosure of D5040 series must be cleaned only with a damp or antistatic cloth.
Any penetration of cleaning liquid must be avoided to prevent damage to the unit. Any unauthorized modification must be avoided.
All circuits connected to D5040 series must comply with the overvoltage category II (or better) according to EN/IEC60664-1.
Start-up
Before powering the unit, check that all wires are properly connected and verify their polarity, also check that Intrinsically Safe conductors and cable trays are segregated (no direct
contacts with other non I.S. conductors) and identified either by color coding, preferably blue, or by marking. Check conductors for exposed wires that could touch each other causing
dangerous unwanted shorts. The status yellow LED must be in accordance with the condition of the corresponding input line.
