The ALSTOM LYNGSOE MARINE DRM401 962.004.800 is a specialized digital relay module designed for the maritime industry’s rigorous automation and alarm monitoring requirements. Serving as a key output component within the Stella 2100 and UCS 2100 series, this module provides reliable switching for external circuits, such as engine room alarms, auxiliary machinery control, and safety system interlocks. Its ruggedized design, often associated with SAM Electronics or STN Atlas platforms, ensures operational stability under the constant vibration and temperature fluctuations found in vessel engine rooms and bridge control consoles.

Product Q&A

Q1: What is the primary function of the DRM401 in a marine automation system? A1: The DRM401 (Digital Relay Module) acts as the execution interface for the automation system. It receives logic commands from the central processing unit and switches physical relay contacts to activate external devices like pumps, solenoids, or audible and visual alarm indicators.

Q2: Is the DRM401 interchangeable with other modules like the REM 401? A2: While they share the same physical form factor, the REM 401 typically functions as a “Relay and Input” module, offering both inputs and outputs. The DRM401 is dedicated specifically to digital relay outputs. You must verify the specific wiring and system software configuration before attempting a replacement.

Q3: How do I identify the correct hardware revision for my system? A3: Always cross-reference both the model number (DRM401) and the specific part number (962.004.800 or 271.130.433.D). These numbers indicate the specific revision of the PCB and internal components, ensuring compatibility with the legacy system firmware on board the vessel.
