Expansion Receiver Module, Non-isolated
The non-isolated Expansion Receiver Module (IC200ERM002) interfaces an
expansion “rack” to a VersaMax PLC or VersaMax NIU I/O Station system. The
expansion rack can to 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 may
be used without an Expansion Transmitter Module (IC200ETM001) in the PLC or
I/O Station if there is only one expansion rack in the system or if the cable length is
one meter or less. An Expansion Transmitter Module is required if there are multiple
expansion racks or for a longer cable. Maximum cable length for this non-isolated
module is 15 meters.

High speed bus expansion interface
Supports Hold Last State
System fault isolation
Three LEDs indicate module power status and expansion port status
No DIP switches to set, easy software configuration into PLC system
Power supply mounts directly to module
Differential or single-ended operation
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.
