Installing Relay-Style Interposing I/O Terminals IC200CHS111 and IC200CHS112
The Relay-Style Interposing I/O Terminals (IC200CHS111 and IC200CHS112)
each provide dry contacts capable of switching high current outputs (up to 8A).
For the Relay Style Interposing I/O Terminals, power for operation of the relay
coils must be provided by an external 24 V DC power supply. This power must
be provided to both the main base (IC200CHS111) and the expansion base
(IC200CHS112). Connection of this external power supply is made at the
terminals A17 and A18 (B17 and B18 for the expansion base). This power
connection is for the relay coils only.
User loads must be powered by an
external source.
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: NO (Normally Open), C (Common), and NC (Normally
Closed). Loads may be connected between C and NO, C and NC, or both.

Relay-Style Interposing I/O Terminals, Terminal Wiring
Each terminal accommodates:
One solid (0.2 to 4.0mm
2
cross section) or stranded (0.2 to 2.5mm
2
cross
section), AWG #12 to AWG #24.
When inserting two wires in the same position, the wires must be the same size
and type (solid or stranded), as specified below:
Rigid or flexible wires: 0.2 to 1.5mm
2
cross section.
Stranded wires with ferrules, no plastic sleeve: 0.25 to 0.75mm
2
cross
section
Stranded wires with twin ferrule, with plastic sleeve
Recommended torque for the terminal screws is 0.5 to 0.6 Nm.
