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.
