Application
The IOM47 field controller is part of the Metasys® system
Field Equipment Controller family. Input/Output Module
(IOM) controllers 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 field 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, 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 operation
of the IOM Input/Output Module is not affected by
the selection of the BACnet or the N2 protocol in
the host controller.
Important: In Metasys system smoke control
applications, use only the MS-IOM4710-0U
and MS-IOU4710-0U models that are UL
Listed, UUKL/UUKLC 864 Listed, Smoke
Control Equipment. For Metasys system
smoke control applications, you must refer
to the Metasys System UL 864 Ninth Edition
UUKL/UUKL7 Smoke Control System
Technical Bulletin (LIT-12011252) for
detailed requirements and procedures for
installing and operating UUKL/UUKLC 864
Listed Metasys system devices. Failure to
meet the requirements or follow the
procedures in the Metasys System UL 864
Ninth Edition UUKL/UUKL7 Smoke Control
System Technical Bulletin (LIT-12011252)

Wiring
Observe the following guidelines when wiring a controller:
Input and Output Terminal Blocks
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.
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.
Figure 4: FC Bus Terminal Block Wiring
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).
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.
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.
IOM47 Input/Output Module Installation Instructions

Figure 5: SA Bus Terminal Block Wiring
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.
Figure 7: 24 VAC Supply Power 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 controller is an
RJ-12, 6-position modular jack that provides a connection
for devices on the SA bus, a Bluetooth® Wireless
Commissioning Converter, ZigBee® wireless dongle, or
a ZFR1811 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 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 ZFR1811 Wireless Field Bus Router.
To configure a controller for use with the ZFR1800 Series
Wireless Field Bus system:
Note: IOMs can talk wirelessly on the FC bus only.

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.

Setup and Adjustments
Setting the Device Addresses
Metasys field controllers are master devices on MS/TP
(SA or FC) buses. Before operating controllers on a bus,
you must set a valid and unique device address for each
controller on the bus. You set a controller's device
address by setting the positions of the switches on the
DIP switch block at the top of the controller (Figure 3).
Device addresses 4 through 127 are the valid addresses
for these controllers.
The DIP switch block has eight switches numbered 128,
64, 32, 16, 8, 4, 2, and 1 (Figure 9). Switches 64 through
1 are device address switches. Switch 128 is a mode
switch that enables a controller to operate on a ZFR1800
Series Wireless Field Bus. Switch 128 must be set to off
for all hard-wired SA and FC bus applications. Set switch
128 to ON for wireless FC bus applications only.
Figure 9: Device Address DIP Switch Block Set to
Address 21
Note: Controllers ship with switch 128 ON and the
remaining address switches off rendering the
controllers wired slave devices, which do not
operate on MS/TP buses, but will not interfere
with bus operation. Set a valid and unique device
address on the controller before applying power
to the controller on the bus.
To set the device addresses on Metasys field controllers:
1. Set all of the switches on the address DIP switch
block (128 through 1) to Off.
2. Set one or more of the seven address switches (64
though 1) to ON, so that the sum of the switch
numbers set to ON equals the intended device
address. See Table 6 for valid device addresses.
Set the highest number switch that is less than or
equal to the intended device address to ON. Then
continue setting lower numbered switches until the
total equals the intended address. For example, if the
intended device address is 21, set switch 16 to ON
first, then set switch 4 ON, followed by switch 1
(16+4+1= 21). See Figure 9.
IOM47 Input/Output Module Installation Instructions
3. Set switch 128 to ON only for controllers on a
ZFR1800 Series Wireless Field Bus application. For
all hard-wired SA and FC bus applications, ensure
that switch 128 is set to Off.
Note: Do not connect a controller with switch 128
set to ON to an active (hard-wired) SA or FC
bus. When a controller with switch 128 set to
ON and a device address from 4 to 127 is
connected to a wired field bus, the entire field
bus is rendered inoperable until the controller
is disconnected or switch 128 is set to Off.
Refer to the ZFR1800 Series Wireless Field Bus
System Technical Bulletin (LIT-12011295) for more
information on device addresses in wireless
applications.
4. Set a unique and sequential device address for each
of the controllers connected on the SA or FC bus
starting with device address 4.
To ensure the best bus performance, set sequential
device addresses with no gaps in the device address
range (4, 5, 6, 7, 8, 9, and so on). The controllers do
not need to be physically connected on the bus in
their numerical device address order.
5. Write each controller's device address on the white
label below the DIP switch block on the controller's
cover.
Table 6 describes the FC bus and SA bus devices
addresses for Johnson Controls MS/TP
communications bus applications.
Refer to the MS/TP Communications Bus Technical
Bulletin (LIT-12011034) for more information on
controller device addresses and how to set them on
MS/TP buses.

Valid for MS/TP Master controllers on wireless
FC Buses only.
Note: Do not connect a controller with switch
128 ON to an active (hard-wired) SA or FC
Bus. When a controller with switch 128 ON
and a device address from 4 to 127 is
connected to a wired field bus, the entire field
bus is rendered inoperable until the controller
is disconnected or switch 128 is set to Off.
Removing the Controller Cover
Important: Electrostatic discharge can damage
controller components. Use proper
electrostatic discharge precautions during
installation, setup, and servicing to avoid
damaging the controller.
Important: Disconnect all power sources to the
controller before removing cover and
changing the position of any jumper or the
EOL switch on the controller. Failure to
disconnect power before changing a jumper
or EOL switch position can result in damage
to the controller and void any warranties.
The controller cover is held in place by four plastic latches
that extend from the base and snap into slots on the
inside of the housing cover.
To remove the controller cover:
1. Place your fingernails under the two cover lift tabs
(Figure 3) on the sides of the housing cover and
gently pry the top of the cover away from the base to
release the cover from the two upper latches.
2. Pivot the top of the cover further to release it from the
lower two latches.
3. Replace the cover by placing it squarely over the
base, and then gently and evenly push the cover on
to the latches until they snap into the latched position.
IOM47 Input/Output Module Installation Instructions
Setting the End-of-Line (EOL) Switch
Each controller has an EOL switch, which, when set to
ON, sets the controller as a terminating device on the
bus. See Figure 10 for the EOL switch location. The
default EOL switch position is Off.
Figure 11: End-of-Line Switch Positions
To set the EOL switch on a controller:
1. Determine the physical location of the controller on
the SA or FC bus.
2. Determine if the controller must be set as a
terminating device on the bus.
Note: The EOL termination rules for SA buses and
FC buses are different. Refer to the MS/TP
Communications Bus Technical Bulletin
(LIT-12011034) for detailed information
regarding EOL termination rules and EOL
switch settings on SA and FC buses.
3. If the controller is a terminating device on the FC bus,
set the EOL switch to ON. If the controller is not a
terminating device on the bus, set the EOL switch to
Off.
When a controller is connected to power with its EOL
switch set to ON, the amber EOL LED on the
controller cover is lit.

Input/Output Jumper Settings
Binary Output (BO) Source Power
Selection Jumpers
Risk of Electric Shock: Disconnect the supply power
to the controller before attempting to adjust the Binary
Output Source Power Selection Jumpers. Failure to
disconnect the supply power may result in electric shock.
UI Current Loop Jumpers
The current loop fail-safe jumpers are on the circuit board
under the controller cover near the UI terminals (Figure
10). When a UI is defined (in the system software) as a
4-20 mA Analog Input and the UI’s current loop jumper
is in the Disabled (default) position (Figure 13), the 4-20
mA current loop circuit opens whenever power to the
controller is interrupted or off.
Figure 13: Current Loop Jumper Positions
Mise En Garde: Risque de décharge électrique:
Débrancher l'alimentation de l'controller avant tout
réglage du Binary Output Source Power Selection
Jumpers. Le non-respect de cette précaution risque de
provoquer une décharge électrique.
Important: Do not connect an external power source
to a binary output (BO) when the BO power
source jumper is in the internal power (INT)
position. Connecting external power to a
BO that sources internal power can damage
the controller and void any warranties.
The BO source power selection jumpers determine
whether a BO provides internal power (sourced from the
controller) to the output load (INT position) or requires
an external power source (EXT position) for the output
load. Figure 12 shows an example of a controller BOs
and the associated power selection jumpers to the right
of the BOs terminal block.
Figure 12: Example Binary Outputs and the
Associated Source Power Jumper Positions
Setting the current loop jumper to the Enabled position
(Figure 13) connects an internal 100 ohm resistor across
the UI terminals, which maintains the 4-20 mA current
loop circuit even when power to the controller is
interrupted or off.
Important: Current Loop jumpers must be in the
Disabled (default) position for all UIs that
are not set up to operate as 4-20 mA analog
inputs.
Table 7 identifies the current loop jumpers associated
with each UI on the IOM47 controller.
