Industrial Applications

1. Solenoid valve bank control

Drives multiple 24 VDC solenoids in a compact machine manifold from a single PLC output card, using the 32 sinking channels and 0.5 A point capability.

Problem Solved

Simplifies high-density valve control without external relay packs for many low-power DC loads.

2. Stack light and alarm load switching

Controls grouped 12–24 VDC tower lights, buzzers, and annunciators in industrial panels where many discrete outputs are needed and the current per device stays within the unit limits.

Problem Solved

Provides dense discrete output capacity for machine status indication with direct DC switching.

3. Compact machine actuator interfacing

Interfaces a CS1 PLC to numerous small DC actuators such as relays, contactors, and pilot devices when the machine requires many output channels in a control cabinet environment.

Problem Solved

Reduces wiring complexity and enables centralized control of many low-current actuators from one output module.
