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.
