MTL MTL5516C Switch/Proximity Detector Interface

Overview

The MTL5516C serves as a switch/proximity detector interface for hazardous-area installations. It provides galvanic isolation and line fault detection (LFD) to ensure safe, reliable signal transmission. Moreover, the dual-channel design supports independent operation, improving flexibility in critical automation systems. With SIL2/SIL3 safety compliance, this device performs well in demanding industrial applications.
