Description
Pleiger EHS-CM 2 Control Module
Electro-Hydraulic System (EHS) Marine Valve Controller
This genuine Pleiger EHS-CM 2 control module was carefully salvaged from a working shipboard marine automation cabinet during a system retrofit. The unit is in excellent physical condition, featuring undamaged screw terminal blocks, crisp front-panel markings, and intact indicator lights. It has been bench-tested for signal translation and local/remote toggle operations.
Product Overview
The Pleiger EHS-CM 2 (Part Number: 9341100070) is an industrial-grade, marine-specialized control module designed for the precise management of Electro-Hydraulic Systems (EHS). This module functions as the vital logic hub between shipboard central control architectures and localized hydraulic valve actuators.
Engineered specifically to handle the extreme demands of marine engine rooms, ballast systems, and deck machinery, the EHS-CM 2 translates electrical inputs into precise valve actuator drive commands. It features dedicated dials for delay times, visual status LEDs, and a local/remote toggle switch that ensures safe operations during diagnostics or emergency overrides.

Key Features & Applications
- Robust Marine Resilience: Built from the ground up to resist intense structural vibrations, salty damp environments, and broad temperature ranges typical of maritime and offshore operations.
- Flexible Manual Override: Local/Remote physical toggle switch provides instant manual intervention capability directly at the cabinet front.
- Adjustable Delay Configuration: Features an accessible rotational potentiometer dial for fine-tuning actuation timing (10-110s) to limit hydraulic water-hammer shock.
- Standardized Fitting: Standard DIN-rail layout with easily accessible screw termination bars on the top and bottom faces for simple installation and wiring maintenance.
