Applications with safety brakes and holding brakes require reliable brake monitoring. This eliminates all potential hazards for the user – even when the drive is in a de-energised state. With the stand-alone safety relay PNOZ s50, Pilz is offering an economical solution for controlling two safety brakes up to category PL e of EN ISO 13849-1.

On the safety relay PNOZ s50, temporary overexcitation is followed by voltage reduction, for which parameters can be set. The resulting short ventilation times help to make your application more energy-efficient. On the one hand, safe brake control enables rapid switching in emergency situations. On the other hand, it ensures slow, low-wearing switching in normal operation, thereby reducing maintenance requirements.
