1. Product Title

SMTA‑378‑ Discrete Signal Input‑Output Interface Module

2. Product Overview

SMTA‑378 is a field interface module for discrete digital signal transmission in marine‑grade automation systems. It galvanically isolates on‑site binary status signals and control commands between field devices and main control boards, preventing ground‑loop interference and protecting system electronics from field‑side surge damage. SMTA‑378 serves as maintenance spare to restore digital signal transmission capacity without modifying existing cabinet wiring.
