The safety relays PNOZ s1 and PNOZ s2 are suitable for monitoring E-STOP and safety gates. The devices PNOZ s3, PNOZ s4 and PNOZ s4.1 can also be used to monitor E-STOP and safety gates, their area of application also includes monitoring of light guards. In the application at plants and machines, one PNOZsimga safety relay is used per safety function. Below you find an overview of the application options of the individual devices.
