Expansion Modules
Expansion modules can be used to extend the I/O Station and add more modules.
There are two basic types of VersaMax I/O expansion systems, Multi-Rack and
Two-Rack Local:
S Multi-Rack: A VersaMax PLC or NIU I/O Station with an Expansion
Transmitter Module (IC200ETM001) and one to seven expansion “racks”, each
with an Expansion Receiver Module (IC200ERM001 or IC200ERM002). If all
the Expansion Receivers are the Isolated type (IC200ERM001), the maximum
overall cable length is 750 meters. If the expansion bus includes any non-
isolated Expansion Receivers (IC200ERM002), the maximum overall cable
length is 15 meters.
