Description
Core Product Summary
The SAM Electronics / Lyngsø Marine REM401 is a relay and input module associated with marine automation and shipboard control systems. It is identified by the model designation REM401 and the part number 962.003.400, with 271.123 854.E also appearing in product identification records.
The module is intended for use within a compatible marine automation installation. Its relay-and-input classification indicates its general functional category, but the available identification information does not establish individual channel assignments, electrical ratings, or terminal-level wiring details. When assessing the REM401 for maintenance or replacement, compare the complete part number, PCB markings, connector arrangement, and installed control-system documentation. Similar-looking modules or matching family names alone do not establish interchangeability.

Detailed Product Overview
Product identification and function
The SAM Electronics / Lyngsø Marine REM401 is identified as a relay and input module for marine automation equipment. The part number 962.003.400 is a key identifier, while 271.123 854.E provides an additional reference for matching the board.
Relay and input modules generally form part of the electrical interface between an automation controller and external equipment. However, the exact circuitry and channel-level functions of the REM401 must be determined from the applicable system documentation.
Integration into marine control equipment
The module should be evaluated as part of its host automation system rather than as an independent general-purpose I/O device. The control-system architecture determines the required electrical interfaces, signal assignments, and module installation arrangement.
When investigating a fault or planning a component replacement, first establish the module’s installed position and identify the circuits connected to it. Do not infer contact ratings, input voltage ranges, or terminal assignments from the REM401 model name alone.
Selection and maintenance considerations
For procurement and maintenance, record the complete REM401 designation and all visible part numbers. Compare the board markings, connector configuration, and physical arrangement with the installed module and equipment documentation.
Before installation, establish the required supply conditions, signal characteristics, relay contact requirements, and wiring details from the relevant technical documentation. Confirm that the proposed module is intended for the same host-system configuration. A matching model family or similar PCB layout is not sufficient evidence of electrical interchangeability.
REM401
Applications & System Role
The REM401 is a relay and input module associated with SAM Electronics / Lyngsø Marine marine automation systems. Within a control architecture, relay and input modules provide electrical interfaces between control equipment and connected signals or circuits.
The exact role of this particular REM401 depends on the host system and its documented configuration. Its model designation does not, by itself, establish the number of inputs, relay contact arrangement, supported signal types, or electrical load limits.
For maintenance teams, the module is most relevant when identifying a component installed in an existing marine control system. Accurate identification requires the complete model and part numbers, board markings, connector layout, and host equipment information. These details help establish whether a candidate module corresponds to the installed hardware.
