1.6 Expansion Modules

Introduction
For public disclosure
There are two basic types of VersaMax I/O expansion systems, Multi-Rack and
Single-ended:
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.
