Siemens SIRIUS safety relay Basic unit 3SK2 seri

The SIRIUS safety switch device from Siemens' basic device series 3SK2 is a highly advanced solution for demanding safety applications. With a compact design of only 22.5 mm in width, this device offers a variety of inputs and outputs designed for the implementation of multiple independent safety functions. It can be parameterized using the SIRIUS Safety Engineering software, which allows for easy commissioning and comprehensive diagnostic capabilities. The device supports an input voltage of 24 V DC and is certified up to SIL 3 (IEC 62061) and Performance Level e (ISO 13849-1). Integration into existing systems is facilitated by the option to expand with 3SK1 output expansions and connection to fail-safe motor starters 3RM1. The pre-configured logic blocks enable simple realization of functions such as muting and safety door monitoring, enhancing flexibility and efficiency in application.
