Multiplexed I/O Modules
(T7491)
Issue 1, March, 06
Multiplexed I/O modules provide two RS-422 serial port
interfaces between the Regent system and ICS’s remote
multiplexed I/O Unit (MIU) equipment, providing an
economical interface to digital inputs and outputs. MIU
equipment is often used for matrix and mimic displays in
safety and fire and gas systems or low cost, remote simplex
input and outputs.
Features
• Occupies one slot in the I/O chassis.
• Two isolated RS-422 serial ports for remote multiplexed I/O.
• Supports up to 512 digital inputs and 256 digital outputs of
remote MIU equipment.
· Individual front panel indicators on each module show module
active and fault status; and transmit, receive and fault status
for each port.
• Serial ports can be used in simplex or duplex modes (with
2oo2 testing in dual mode).
· 1000 volt minimum electrical isolation between serial ports
and between serial and logic circuits.
· TÜV certified, Risk Class 5, non-interfering.
Multiplexed I/O modules support multi-drop connection to
remote MIU equipment up to 4000 feet (1220 meters) away at
19200 baud. The two serial ports of the Mux I/O module can
be configured for simplex or duplex mode. In duplex mode,
2oo2 voting is performed on the I/O data.
