The device consists of a power section, the electronics and two redundant relays with interlocked opposing contacts for the enabling and signaling paths.

The range includes relays for Emergency-Stop circuits, monitoring of safety mats, bumpers, protective guards and monitoring of two-hand controls, complying with safety category 3 or 4, as per the EC machinery directive standards EN 954-1 and IEC/EN 60 204-1.

Safety relays for Emergency-Stop and monitoring protective guards are available for single or dual channel applications, thus increasing the range of possible application
