Industrial Applications

1. PLC actuator switching for mixed-voltage machine loads

Use the 16 relay outputs to switch AC or DC loads from a CJ PLC where the field devices require 5–250 V compatibility and up to 2 A per channel.

Problem Solved

Eliminates the need for separate interposing relays in moderate-load control circuits.

2. Panel-level control of solenoids, pilot lamps, and small contactors

The module fits control cabinets that need many discrete on/off points with simple screw-terminal wiring and relay contact isolation.

Problem Solved

Provides dense discrete output expansion with straightforward wiring and isolated contacts.

3. Retrofit expansion for CJ-series automation lines

A compact 16-point output unit can extend existing CJ I/O Bus systems in legacy equipment without changing the base PLC architecture.

Problem Solved

Adds output capacity to installed CJ controllers while preserving the existing system bus and wiring style.
