Description
Product Overview
The SAM Electronics / Lyngsø Marine AEM402 is an analog input module used in marine automation equipment. Its purpose is to acquire analog signals from connected instrumentation and make those measurements available to the wider vessel monitoring and control system. Such signals may represent equipment or process conditions, but the exact sensor types and measurement ranges supported by this particular revision must be established from the original system documentation.
The reference 271.138 714 is associated with the AEM402, and marine equipment listings also connect the module to Lyngsø Marine part number 962.004.200. Other listings show suffix variants such as 271.138 714/E, 271.138 714/G, and 271.138 714/H. These variations should not be treated as interchangeable without checking the module label, circuit-board revision, and applicable wiring diagram.
For maintenance teams, the practical priority is confirming the replacement against the installed marine control system. Check the connector arrangement, field termination, signal types, and any associated multiplexer or controller hardware. A replacement that fits mechanically may still differ electrically or in its supported signal configuration. If the module is used in a vessel’s operational monitoring or alarm system, request evidence of functional testing and establish the required post-installation checks before returning the system to service.
Product Introduction
The AEM402 271.138 714 is a marine automation analog input module associated with SAM Electronics and Lyngsø Marine systems. It is intended for compatible shipboard control and monitoring installations that require analog signal acquisition.
Before purchasing, verify the complete part number, including its suffix, and compare it with the original module. Confirm the installed system model, input signal requirements, wiring arrangement, and related reference number. Do not infer channel count, measurement accuracy, or electrical compatibility from the AEM402 designation alone.
