EATON PL9-C4-2-DC Industrial Control Module

This compact 24V DC control module serves as a critical interface for managing discrete I/O signals in industrial automation systems. Commonly deployed in manufacturing cells and process control environments, it handles tasks like valve actuation sequencing and motor starter coordination with millisecond-level response times. Its modular design allows direct integration with PLC backplanes while maintaining electrical isolation between control and power circuits.

Common Applications

We frequently see this module deployed in packaging machinery control panels and conveyor system interlocks. One customer in the automotive sector successfully used it to replace legacy contactor arrays in robotic welding cells, achieving 30% faster cycle times. For those maintaining legacy systems, we also stock compatible components like the 3BHB013088R0001 (ABB AC1027) and IC698CPE010 (GE RX3i CPU). Its screw-terminal design simplifies field wiring during retrofits.

The module’s 4 relay outputs handle inductive loads up to 5A each, making it suitable for controlling solenoids, small motors, and indicator towers. We’ve also seen it used in HVAC control applications for managing chiller pump sequences and damper actuators.
