MTL5011B Switch/Proximity Detector Interface Safety Barrier 5018/5011B/5042/5046/5021
The MTL5011B enables a safe-area load to be controlled by a switch
or proximity detector located in a hazardous area. A relay output
is provided. Phase reversal control allows an alarm condition to be
signalled for either state of the sensor. A selectable line fault detect
(LFD) facility detects an open or short circuit in the field circuit.
