These are ideal for monitoring the 8k2 resistor in safety edges and pressure sensitive contact mats applications, such as machine safety applications.
In addition to the automatic reset function, the ESD3-03 unit has an additional status relay (not for safety shutdown) that can be used for information on the system operation. The safety relays are positively driven and can carry a load of 2 A.
This switching unit is rated performance level e, cat. 3 according to EN ISO 13849-1
