Expansion Base – IC200CHS122
This interposing base has a connector (J2) for attaching to the expansion
connector of the Main Base (IC200CHS121) and provides 36 box-style
terminals for field I/O wiring and power connections.
The Expansion Base provides connection for terminals on the “B” side of the
VersaMax connector (B1-B18). In addition, it has two groups of common
terminals (Y1-Y8 and Z1-Z8) for connecting two-wire devices without additional
auxiliary terminal blocks. Individual fuses (0.5 A) exist between each terminal
B1-B16 and its corresponding pin on the VersaMax cable connector. The
Expansion base includes the cable required to connect to the main base.
