The PLEIGER CM 4 is a compact, DIN-rail mounted control module designed for precise operation of electro-hydraulic actuators in industrial and marine applications. It supports dual power supply inputs (24VDC and 230VAC) and provides dedicated control logic for valve opening/closing, with integrated safety features such as overcurrent protection and position feedback. The module ensures reliable actuation control in harsh environments, making it ideal for shipboard systems, oil and gas processing, and water treatment facilities where stable and safe valve operation is critical.
