Flexible implementation of simple safety requirements with 3SK

Are you looking for a quick and easy way to realize safe systems? We have the solution: SIRIUS 3SK safety relays The new safety relays offer outstanding simplicity, flexibility and efficiency. Their modular design simplifies planning, commissioning and the expansion of systems. They enable safety functions such as EMERGENCY-STOP and protective door monitoring up to SIL 3 and PL e to be implemented, really easily without programming and in minimum time. The safety relays are approved for applications up to SIL 3 (IEC 61508/IEC 62061) or PL e (EN ISO 13849-1) and are used internationally. To meet different requirements, the 3SK1 safety relay is available as a Standard and Advanced basic unit range, as well as the 3SK2 safety relay. The devices can be used for stand-alone solutions and for integrated solutions.

Full safety in all applications with 3TK28
