MTL MTL4016 Switch/Proximity Detector Interface Unit

Description

The MTL4016 enables safe signal transmission from hazardous areas to control and shutdown systems. It features independent phase-reversal switches, allowing alarm signals to be configured for either state of the sensors. The module also includes line fault detection (LFD) for broken or shorted lines, ensuring reliable operation.
