Expansion Modules
There are two basic types of VersaMax I/O expansion systems, Multi-Rack and
Two-Rack Local:
 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.
