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.
IC200ERM002 ERMs
IC200ERM001 ERMs
Two-Rack Local: A PLC or NIU I/O Station connected directly to one expansion
rack with non-isolated Expansion Receiver Module (IC200ERM002). Maximum cable
length is 1 meter.
