Ensures insulation of input / output. Processing of the lock signal from the system, mushroom breaker, etc. to SPDT and SPST transducers. It has the option to select circuit monitoring type: input line monitoring (pulsating test), monitoring of low voltage or monitoring of short-circuit, using DIP switches.
Implements SIL 3 function for NE loading (normal supply)
– switching off the input shuts down the load
