Description
Main Base – IC200CHS111
The Relay-Style Interposing I/O Terminals (IC200CHS111 and IC200CHS112) each provide dry contacts capable of switching high current outputs (up to 8A). The relays on these interposing terminals are intended to be controlled with standard 24VDC 0.5A VersaMax output modules (IC200MDL740 and IC200MDL750). Each relay is replaceable, individually fused, and includes status indication.
The Interposing Relay Base has a connector (J1) for attaching a cable from the Connector-Style I/O Carrier (IC200CHS003) and 50 box-style terminals for field I/O wiring and power connections. The Interposing Relay Base also has an expansion connector (J2) that can be used to attach to an Interposing Relay Expansion Base (IC200CHS112).

Carefully inspect all shipping containers for damage. If any equipment is damaged, notify the delivery service immediately. Save the damaged shipping container for inspection by the delivery service. After unpacking the equipment, record all serial numbers. Save the shipping containers and packing material in case it is necessary to transport or ship any part of the system.

Main and Expansion Base Two different versions of the Relay-Style Interposing I/O Terminals are available, the main and expansion bases. The Main Base, IC200CHS111, is for use with the 16 point VersaMax module (IC200MDL740) or points 1-16 of the 32 point VersaMax module (IC200MDL750). The Expansion Base, IC200CHS112, is for use with points 17-32 of the 32 point VersaMax module (IC200MDL750).

Expansion Base – IC200CHS112 The Interposing Relay Expansion Base has a connector (J2) for attaching a ribbon cable to the expansion connector of the Main Base (IC200CHS111) and 50 box-style terminals for field I/O wiring and power connections. The Expansion base includes a ribbon cable for connecting the expansion base to the main base.

Field Wiring
Relay Specifications
Power for operation of the relay coils must be provided by an external 24VDC power supply. This power must be provided to both the main base and the expansion base. Connection of this external power supply is made at the terminals A17 & A18 (B17 & B18 for the expansion base). This power connection is for the relay coils only. User loads must be powered by an external source.
The field-replaceable, form-C relay used in IC200CHS111 and IC200CHS112 is manufactured by Omron Electronics (part number G2R-14). The relay has the following specifications: Number of Poles
1 Pole
Each relay, status LED and fuse is labeled to indicate the specific point on the VersaMax output module they are associated with. Components labeled A1-A16 correspond to points Q1-Q16. Components labeled B1-B16 correspond to points Q17-Q32. Each point is associated with 3 terminal connections, labeled NO (Normally Open), C (Common), and NC (Normally Closed). User loads may be connected between C and NO, C and NC, or both.
