The Expansion Receiver Module, Isolated (IC200ERM001) interfaces an
expansion "rack" to a VersaMax PLC or NIU I/O Station system. The expansion
rack can include up to eight Versamax I/O and special-purpose modules. A
VersaMax power supply installed on the Expansion Receiver Module provides
operating power for the modules in the expansion rack. This module must be
used with an Expansion Transmitter Module (IC200ERM001) in the PLC or I/O
Station. The total overall length of the expansion cable can be up to 750 m.
This module provides up to 500 V DC isolation.
High speed bus expansion interface
Supports up to 7 expansion racks
Supports Hold Last State
System fault isolation
Three LED indicators provide module power status and expansion port
status
No DIP switches to set, easy software configuration into PLC system
Power supply mounts directly to module
500 V DC isolation
The Expansion Receiver Module supports hold last state operation of the output
modules in the event of loss of communications with the CPU/NIU. It also
permits isolation and repair of a faulty module within a rack.
