Pilz Automation PNOZ s50 provides contactless control of two brakes.

14-sept-pilz-safety-relay-360Pilz Automation released its safety relay PNOZ s50 that can control two powerful brakes simultaneously without the use of contacts. The relay is designed to control holding brakes or safety brakes in the 24/48 Volt DC range on vertical axes up to PL e of EN ISO 13849-1 or SIL CL 3 of EN/IEC 62061. The relay has an output current of 3.5 amps, with peak currents of 6.5 ampere. The PNOZ s50 also offers fast shutdown of the power circuits or a slow shutdown for low-noise switching of the brakes. Four safety-related and two standard inputs are available to activate the functions.
