Brake control devices - PNOZ s50

Safe control of motor brakes and safety brakes

Both motor brakes and safety brakes can be safely controlled with the safety relay PNOZ s50. The stand-alone device PNOZ s50 controls and monitors two safety brakes up to the highest category PL e of EN ISO 13849-1 / SIL CL 3 of EN/IEC 62061 or one brake up to PL d of EN ISO 13849-1 / SIL CL 3 of EN/IEC 62061. The safety relay has two dual-pole, safe electronic digital outputs for 24 VDC with 4,5 A each. On the safety relay PNOZ s50, temporary overexcitation is followed by voltage reduction, for which parameters can be set.
