IC200ERM002
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 m.

 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.
