Industrial Applications

1. High-density machine actuator switching

Ideal for compact PLC panels that must switch many 24 VDC solenoids, pilot lamps, or relays from a single CJ-series rack slot.

Problem Solved

Reduces rack space and wiring complexity while providing 64 discrete outputs for dense machine sequencing.

2. Packaging line zone control

Suitable for packaging machines with many coordinated output devices such as valves, indicators, and stack lights operating within 12–24 VDC control circuits.

Problem Solved

Supports many low-voltage DC loads with fast response times for synchronized machine motion and interlocks.
