Description

Safety is a SIRIUS business - 3SK safety relays 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. The safety relays are certified in accordance with IEC 62061 and ISO 13849-1 and are internationally applicable. The 3SK1 and 3SK2 versions of the device are available to meet differing requirements. The devices can be used for both stand-alone and integrated solutions. There are many facets to machine safety - but there is always a case for SIRIUS 3SK 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. 3SK1 standard and advanced basic units With SIRIUS 3SK1 safety relays, safety functions can be simply parameterized with DIP switches. Operation of a sensor is always followed by fail-safe disabling of all outputs of these basic units. •Seamless integration: reduces wiring effort for fail-safe SIRIUS 3RM1 motor starters •More free space: fewer basic units and main circuit component
