Fuse-Style Interposing I/O Terminals 
Main Base – IC200CHS121 
This interposing base has a connector (J1) for attaching a cable from the 
Connector-Style I/O Carrier and 36 box-style terminals for field I/O wiring and 
power connections.   
 
This base provides connection for the terminals on the “A” side of the VersaMax 
connector (A1-A18).  Two groups of common terminals (W1-W8 and X1-X8) 
can be used for connecting two-wire devices without additional auxiliary terminal 
blocks. 
Individual fuses (0.5 A) exist between each terminal A1-A16 and its 
corresponding pin on the VersaMax cable connector.  This base also provides 
an expansion connector (J2) to attach to the Interposing Fuse Expansion Base 
(IC200CHS122).
