SIRIUS 3SK safety relays offer outstanding simplicity, flexibility and cost-effectiveness. Their modular design simplifies the planning, commissioning and expansion of plants. Simple safety functions, such as EMERGENCY STOP and protective door monitoring up to SIL 3 and PL e, can be quickly implemented without programming. Highlights at a glance There are many facets to machine safety. Regardless of whether the application involves the fail-safe monitoring of a mechanical or an electronic sensor, there are no major differences between the safety relays that can be used. Therefore, with SIRIUS 3SK you are choosing an extremely lean portfolio. Standard safety applications can be implemented quickly and easily even with 3SK1 safety relays. 3SK2 devices that can be parameterized by software are available for applications with more complex safety requirements. They can be connected to higher-level control systems via PROFINET.
