Safety relay protection module LA016

Used to protect bistable relay from incorrect opération. Ifinput pin 1 is energised for any amount of time (at least 250ms), the electronics ensure that the pull-in coil ofthe relay is connected for a defined time and the contact permanently closes (until activation ofthe drop-out coil). Ifinput pin 3 is energised for any amount oftime (at least250ms), the electronics ensure that the drop-out coil of the relay is connected for a defined time and the contact permanently closes (until activation ofthe pull-in coil). In addition the electronics monitor the voltage and prevent improper switching processes being triggered if undervoltage occurs.
