New safety relay PNOZ s50 from Pilz Automation Safety, L.P.
The new safety relay PNOZ s50 can control two powerful brakes simultaneously without the use of contacts. As such, it provides the required level of safety, particularly in the field of vertical axes: on loading and unloading gantries, machine tools, lifting devices and in stage technology, for example, a suspended load's own weight may be enough to allow the axis to fall unintentionally. Thanks to the reduced cycle times, the safety relay also increases the plants' energy efficiency significantly.
The safety relay PNOZ s50 with emergency stop function 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 special feature about this new development on the market is that two brakes, even brakes from different manufacturers, can be controlled simultaneously using one safety relay. Due to the high output current of 3.5 ampere, PNOZ s50 can control powerful brakes for heavy loads; if necessary up to peak currents of 6.5 ampere.
