The PLEIGER CM3 is a control module belonging to the PLEIGER C-Line series, designed for use within their sophisticated valve remote control (VRC) systems. Primarily utilized in marine and offshore applications, this module acts as an intelligent interface for controlling and monitoring electro-hydraulic actuators. It facilitates communication within the VRC system, often employing the CANopen protocol for robust data exchange between control units, I/O modules, and actuators. The CM3 typically handles signal processing, diagnostics, and status indication, contributing to the overall reliability and efficiency of complex valve automation tasks.
