Application

The IOM47 field controller is part of the Metasys®system
Field Equipment Controller family. Input/Output Module (IOM) controller expand the number of points connected to a Network Automation Engine (NAE), Network Control Engine (NCE), Field Equipment Controller (FEC), or Advanced Application Field Equipment Controller (FAC) to monitor and control a wide variety of HVAC equipment.
IOM controllers operate on an RS-485 BACnet®
Master-Slave/Token-Passing (MS/TP) Bus as BACnet Application Specific Controllers (B-ASCs) and integrate
into Johnson Controls®and third-party BACnet systems.
Note: At CCT Release 10.1 and later, a new capability
was introduced allowing VMAs, FECs, and FACs to communicate by using either the BACnet or the N2 field bus networking protocol. The I/O can be connected through the SA bus to a host controller that is using either the BACnet or the N2 protocol. Only the BACnet protocol is supported when the I/O is connected directly to the trunk using the FC bus.
Important: In Metasys system smoke control
applications, use only the MS-IOM4711-0U and MS-IOU4710-0U at Metasys Release
8.1 that are UL 864 UUKL/UUKLC 10th Edition Smoke Control Listed. For Metasys system smoke control applications, you must refer to the Metasys System UL 864
UUKL Tenth Edition Smoke Control System Technical Bulletin (LIT-12012487) for
detailed requirements and procedures for installing, commissioning, and operating UL 864 UUKL/UUKLC Listed Metasys system devices. The UL 864 UUKL/UUKLC listing for Smoke Control Equipment is voided if (1) you do not use the required software tools at the required versions; or (2) you do not meet the requirements or do not follow the procedures as documented in the
Metasys System UL 864 UUKL Tenth Edition Smoke Control System Technical Bulletin (LIT-12012487).

Wiring

Observe the following guidelines when wiring a controller:
Risk of Electric Shock: Disconnect the power supply before making electrical connections to avoid electric shock.
Mise En Garde: Risque de décharge électrique:
Débrancher l'alimentation avant de réaliser tout raccordement électrique afin d'éviter tout risque de décharge électrique.
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 controller electrical
ratings. Exceeding controller electrical ratings can result in permanent damage to the controller 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
controller components. Use proper electrostatic discharge precautions during installation, setup, and servicing to avoid damaging the controller.
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 controller. Observe the following guidelines when wiring a controller.

Input and Output Terminal Blocks

All of the input terminal blocks are mounted on the bottom of the controller and the output terminal blocks are mounted on the top of the controller. 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 controller, and the other controllers in a daisy-chain configuration using 3-wire twisted, shielded cable as shown in Figure 4. See Table
5 for more information.
4IOM47 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 controller and other SA bus devices in a daisy-chain configuration using 4-wire twisted, shielded cable as shown in Figure 5. See Table
3 for more information.
Figure 5: SA Bus Terminal Block Wiring

SA/FC Bus Port

The SA/FC bus port on the front of the controller is an RJ-12, 6-position modular jack that provides a connection
for devices on the SA bus, a Bluetooth® Wireless
Commissioning Converter, or a ZFR/ZFR Pro Wireless Router (depending on which bus the IOM is operating on).
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 Controllers
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.

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 controller.
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.
5IOM47 Input/Output Module Installation Instructions
Figure 7: 24 VAC Supply Power Terminal Block Wiring
Note: The supply power wire colors may be different on
transformers from other manufacturers. Refer to the transformer manufacturer’s instructions and the project installation drawings for wiring details.
Important: Connect 24 VAC supply power to the
controller 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 controller does not require an earth ground connection.

Wireless Network Applications

The controller can also be installed in a wireless application using a ZFR/ZFR Pro Wireless Field Bus Router.
Important: Wireless operation is not approved for
smoke control applications. Refer to the
Metasys System UL 864 UUKL Tenth Edition Smoke Control System Technical Bulletin (LIT-12012487) for detailed
requirements and procedures for installing, commissioning, and operating UL 864 UUKL/UUKLC Listed Metasys system devices.
To configure a controller for use with the ZFR/ZFR Pro Series Wireless Field Bus system:
Note: IOMs can communicate wirelessly on the FC bus
only.
1. Connect the ZFR/ZFR Pro Wireless Field Bus Router to the FC bus port (RJ-12 modular jack) on the front of the controller.
2. Ensure that the controller's device address DIP switches are set to the correct device address. See
Setting the Device Addresses.
3. Set DIP switch 128 to ON, which enables wireless operation on the controller.
