Siemens safety control relay
WebThe safety relay switches the release circuit if both sensors’ high-signals are available within a time period of 500ms and a closed feedback circuit. If one of two sensor buttons are released, the machine will be safely be switched off by the safety relay. After that, a reactivation of the safety relay is necessary by actuation of both ... WebSafety functions, such as EMERGENCY STOP and protective door monitoring up to SIL 3 and PL e, are quickly implemented without programming. The modular design of 3SK safety relays simplifies the planning, commissioning and expansion of plants. IEC 62061 and ISO 13849-1 certified and internationally applicable.
