Product Overview

MXM402 (271.130.442/F) is a marine‑grade multiplexer module manufactured by Lyngsoe Marine / SAM Electronics. It aggregates multiple analog field signals from vessel sensors and transmitters, time‑division multiplexes these signals and transmits data to the main marine automation controller. Robust mechanical construction tolerates vibration, humidity and temperature fluctuations onboard ships. Obsolete marine spare hardware supplied as refurbished and surplus units for ship automation cabinet maintenance and retrofit projects.

Application Notes

‑ Mount on standard DIN rail inside marine control cabinet. ‑ Use shielded twisted‑pair cables for all analog field wiring. ‑ Observe ESD precautions during module replacement. ‑ Typical deployment: vessel automation system spare‑part stocking for cargo ships, offshore platforms.
