MS-IOU4710-0U
Part No. 24-10144-254, Rev. A
Software Release 8.1
Issued March 2018
Application
The IOU47 field controller is part of the Metasys®system
Field Equipment Controller family. This controller expands
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.
The IOU controller operates on an RS-485 BACnet®
MS/TP Bus as BACnet Application Specific Controllers
(B-ASCs) and integrate into Johnson Controls®and
third-party BACnet systems.
Note: With 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 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.

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 4 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 2 for more
information about I/O terminal functions, requirements,
and ratings.
SA/FC Bus Terminal Block
An IOU 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 IOU 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 5. See Table
4for more information.
Figure 5: FC Bus Terminal Block Wiring
When connecting the IOU 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 6. See Table
3for more information.
Figure 6: 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 6) or the cable
shields on the FC bus (Figure 5).
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.
The SA/FC bus port is connected internally to the SA/FC
bus terminal block. See Table 4 for more information.
The SA/FC bus port pin assignment is shown in Figure
7.

Bus and FC Bus Ports on Controllers
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 8. The middle terminal on the supply
power terminal block is not used. See Table 4 for more
information about the supply terminal block.
Figure 8: 24 VAC Supply Power Terminal Block Wiring
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
Important: Wireless operation is not approved for
smoke control applications. Refer to the
Metasys®System UL 864 10th Edition
UUKL/ORD-C100-13 UUKLC Smoke
Control System Technical Bulletin
(LIT-12012487) for detailed requirements
and procedures for installing,
commissioning, and operating UL 864
