Installing Disconnect-Style Interposing I/O Terminals: IC200CHS101 and 102
and Fuse-Style Interposing I/O Terminals: IC200CHS121 and 122
Disconnect-Style Interposing I/O Terminals (IC200CHS101 and IC200CHS102)
or Fuse-Style Interposing I/O Terminals (IC200CHS121 and IC200CHS122)
interface a VersaMax Connector-Style I/O Carrier to field wiring and provide an
integrated disconnect or fusing option for field devices connected to VersaMax
I/O modules. The Main Base, IC200CHS101 or IC200CHS121, provides
terminals that correspond to the "A" terminals on a VersaMax I/O module. If the
I/O module also has "B" terminals, an Expansion Base, IC200CHS102 or
CHS122) is also needed.
Field wiring to these interposing bases follows the standard wiring diagram for
each module. Terminals A1-A18 and B1-B18 on the interposing terminal bases
are connected in the same fashion as all other bases. The built-in auxiliary
terminals (W1-W8, X1-X8, Y1-Y8, Z1-Z8) are positioned directly below the A or
B terminals to provide for simple two-wire connection of field devices.

Each group of auxiliary terminals has a dedicated terminal to jumper the group
to the appropriate VersaMax terminal (“W” terminal is connection point for
W1-W8 and so forth.). The installation of these jumpers depends on the
grouping present on the I/O module, as illustrated on the following pages.
