MTL4517 2channel DI relay output + LFD alarm safety barrier
MTL4517 product specification as below for your reference.
MTL4517 isolated barrier 2channel DI relay output + LFD alarm safety barrier
MTL4517 – MTL5517 SWITCH/ PROXIMITY DETECTOR
INTERFACE 2-channel, line fault detection, phase reversal The MTLx517 enables
two safe-area loads to be controlled, through a relay, by proximity detectors
or switches located in a hazardous area. Line faults are signalled through a
separate relay and indicated on the top of the module. Switches are provided to
select phase reversal and to enable the line fault detection.
