The SRB range safety monitoring modules serve for the secure evaluation of switching signals. The signals can emanate from mechanical position switches, safety switches, solenoid interlocks or magnetic safety sensors on sliding, hinged or removable guard doors. Depending on the external circuit arrangements, the protection system can be secured up to Control Category 4 to EN 954-1. Further examples of applications and circuit diagrams are shown in the Schmersal Application and Wiring Handbooks.
