Application
The MS-IOM3723 input/output expansion module
is a part of the Metasys system Field Equipment
Controller family. Input/Output expansion modules
(IOMs) expand the number of input/output points
connected to a General Purpose Application
Controller (CGM), VAV Box Controller (CVM), SNC,
SNE, Network Automation Engine (NAE), Network
Control Engine (NCE), Advanced Application Field
Equipment Controller (FAC), Field Equipment
Controller (FEC), or Variable Air Volume Modular
Assembly (VMA) to monitor and control a wide
variety of HVAC equipment.
Note: The IOM3723 model is only available
in certain regions. Contact your local Johnson
Controls representative for more information.
IOM expansion modules operate on an RS-485
BACnet
MS/TP Bus and integrate into Johnson
®
Controls
and third-party BACnet systems. IOMs
®
Note: With Release 10.1 of the Controller
Configuration Tool (CCT), VMAs, FECs, and
FACs can be configured to communicate using
either the BACnet MS/TP or the N2 field bus
networking protocol. The operation of the
IOM is not affected by the selection of the
BACnet MS/TP or the N2 protocol in the host
controller, when the IOM is connected to the
host controller using the SA bus.

Installation
Observe the following guidelines when installing an
expansion module:
• To minimize vibration and shock damage,
transport the expansion module in the original
container.
• Verify that all parts shipped with the expansion
module.
• Do not drop the expansion module or subject it
to physical shock.
Parts included
• One expansion module with removable
terminal blocks (Power and SA/FC bus are
removable)
• One installation instructions sheet
Materials and special tools needed
• Three fasteners appropriate for the mounting
surface (M4 screws or #8 screws)
• One 20 cm (8 in.) or longer piece of 35 mm
DIN rail and appropriate hardware for DIN rail
mount
• Small straight-blade screwdriver for securing
wires in the terminal blocks
