IOM3711 Input/Output Module Installation Instructions
MS-IOM3711-0U
Part No. 24-10144-238, Rev. A
Software Release 8.1
Issued March 2018
Application
The IOM37 input/output expansion module is a part of
the Metasys®system Field Equipment Controller family.
Input/Output Module (IOM) expansion modules expand
the number of points connected to a Network Automation
Engine (NAE), Network Control Engine (NCE), Field
Equipment Controller (FEC), VAV Modular Assembly
(VMA), or Advanced Application Field Equipment
Controller (FAC) to monitor and control a wide variety of
HVAC equipment.
IOM expansion modules operate on an RS-485 BACnet®
MS/TP Bus and integrate into Johnson Controls®and
third-party BACnet systems.
Note: At CCT Release 10.3 and Release Module (RM)
10.2, a new capability allows VMAs, FECs, and
FACs to communicate by using either the BACnet
or the N2 field bus networking protocol. The
operation of the Input/Output Module (IOM) is not
affected by the selection of the BACnet or the N2
protocol in the host controller, when the (IOM) is
connected to the host controller using the SA bus.
Only the BACnet protocol is supported when the
(IOM) is connected directly to the trunk using the
FC bus.

Wiring
Risk of Electric Shock: Disconnect or isolate all power
supplies before making electrical connections. More than
one disconnection or isolation may be required to
completely de-energize equipment. Contact with
components carrying hazardous voltage can cause
electric shock and may result in severe personal injury
or death.
Avertissement: Risque de décharge électrique:
Débrancher ou isoler toute alimentation avant de réaliser
un branchement électrique. Plusieurs isolations et
débranchements sont peut-être nécessaires pour
-couper entièrement l'alimentation de l'équipement. Tout
contact avec des composants conducteurs de tensions
dangereuses risque d'entraîner une décharge électrique
et de provoquer des blessures graves, voire mortelles.
Risk of Property Damage: Do not apply power to the
system before checking all wiring connections. Short
circuited or improperly connected wires may result in
permanent damage to the equipment.
Mise En Garde: Risque de dégâts matériels: Ne pas
mettre le système sous tension avant d'avoir vérifié tous
les raccords de câblage. Des fils formant un court-circuit
ou connectés de façon incorrecte risquent
d'endommager irrémédiablement l'équipement.
Important: Do not exceed the expansion module
electrical ratings. Exceeding expansion
module electrical ratings can result in
permanent damage to the expansion
module and void any warranty.
Important: Use copper conductors only. Make all wiring
in accordance with local, national, and
regional regulations.
Important: Electrostatic discharge can damage
expansion module components. Use proper
electrostatic discharge precautions during
installation, setup, and servicing to avoid
damaging the expansion module.
For detailed information on configuring and wiring an
MS/TP Bus, FC bus, and SA bus, refer to the MS/TP
Communications Bus Technical Bulletin (LIT-12011034).
Terminal Blocks and Bus Ports
See Figure 3 for terminal block and bus port locations on
the expansion module. Observe the following guidelines
when wiring an expansion module.
Input and Output Terminal Blocks
Most of the input terminal blocks are mounted on the
bottom of the expansion module and the output terminal
blocks are mounted on the top of the expansion module.
See Table 3 for more information about I/O terminal
functions, requirements, and ratings.
SA/FC Bus Terminal Block
An IOM can be connected to a Sensor/Actuator (SA) bus
or a Field Controller (FC) bus, but not to both buses
simultaneously. The SA/FC bus terminal block is a
removable, 4-terminal plug that fits into a board-mounted
jack.
When connecting the IOM to an FC bus, wire the bus
terminal block plugs on the expansion module, and the
other expansion modules in a daisy-chain configuration
using 3-wire twisted, shielded cable as shown in Figure
4. See Table 5 for more information.
4IOM3711 Input/Output Module Installation Instructions

Figure 4: FC Bus Terminal Block Wiring
When connecting the IOM to an SA bus, wire the bus
terminal block plugs on the expansion module, and other
SA bus devices in a daisy-chain configuration using 4-wire
twisted, shielded cable as shown in Figure 5. See Table
3for more information.
Figure 5: SA Bus Terminal Block Wiring
Note: The SA PWR/SHLD terminal does not supply 15
VDC. The SA PWR/SHLD terminal is isolated and
can be used to connect (daisy chain) the 15 VDC
power leads on the SA bus (Figure 5) or the cable
shields on the FC bus (Figure 4). The SA bus
supervisor supplies 15 VDC to devices on the SA
bus requiring power.
SA/FC Bus Port
The SA/FC bus port on the front of the expansion module
is an RJ-12, 6-position modular jack that provides a
connection for devices on the SA bus.
The SA/FC bus port is connected internally to the SA/FC
bus terminal block. See Table 5 for more information.
The SA/FC bus port pin assignment is shown in Figure
6.
Figure 6: Pin Number Assignments for Sensor, SA
Bus and FC Bus Ports on Expansion Modules
Supply Power Terminal Block
The 24 VAC supply power terminal block is a gray,
removable, 3-terminal plug that fits into a board-mounted
jack on the top right of the expansion module.
Wire the 24 VAC supply power wires from the transformer
to the HOT and COM terminals on the terminal plug as
shown in Figure 7. The middle terminal on the supply
power terminal block is not used. See Table 5 for more
information about the Supply Terminal Block.
5IOM3711 Input/Output Module Installation Instructions

Figure 7: 24 VAC Supply Power Terminal Block Wiring Important: Connect 24 VAC supply power to the
expansion module and all other network
devices so that transformer phasing is
uniform across the network devices.
Powering network devices with uniform 24
VAC supply power phasing reduces noise,
interference, and ground loop problems.
The expansion module does not require an
earth ground connection.
Wireless Network Applications
Important: Wireless operation is not approved for
smoke control applications. Refer to the
Metasys®System UL 864 10th Edition

Input and Output Wiring Guidelines
Table 3 provides information and guidelines about the
functions, ratings, and requirements for the expansion
module input and output terminals; and references
guidelines for determining proper wire sizes and cable
lengths.
In addition to the wiring guidelines in Table 3, observe
these guidelines when wiring expansion module inputs
and outputs:
• Run all low-voltage wiring and cables separate from
high-voltage wiring.
• All input and output cables, regardless of wire size or
number of wires, should consist of stranded, insulated,
and twisted copper wires.
• Shielded cable is not required for input or output
cables.
• Shielded cable is recommended for input and output
cables that are exposed to high electromagnetic or
radio frequency noise.
• Inputs/outputs with cables less than 30 m (100 ft)
typically do not require an offset in the software setup.
Cable runs over 30 m (100 ft) may require an offset
in the input/output software setup.
