MTL5516C - Switch/Proximity detector interface Two channel, with line-fault detection
The MTL5516C contains two changeover relays, which enable two safe-area loads to be controlled by switches or proximity detectors located in a hazardous-area. When selected, the line-fault detect (LFD) facility detects open or short circuit conditions in the field wiring and also indicates this on the top of the module. Line-Fault Detect and Phase Reversal for the channel are selected by DIL switches on the side of the module and output is provided by the changeover relay contacts
