Description  
The SIRIUS 3RK3121-1AC00 is a central unit from the ASIsafe Basic series, designed for modular safety systems. This unit serves as the core component for monitoring AS-Interface (AS-i) slaves and controlling safe outputs within a safety-related application. It features 1/2F-DI (one or two fault-detecting digital inputs), 6 standard digital inputs (DI), 1F-RO (one fault-detecting relay output), and 1F-DO (one fault-detecting digital output). The device operates on a 24V DC power supply. It is specifically engineered to monitor AS-i slaves and manage up to 8 safe outputs connected to the AS-i bus. Configuration and parameterization are facilitated through the MSS ES software. The unit has a compact width of 45mm and utilizes screw terminals for secure and reliable connections. Meeting stringent safety standards, it is certified up to SIL3 according to IEC 61508 and Performance Level E according to ISO 13849-1. Notably, this particular model does not support the connection of expansion modules, focusing on a streamlined, self-contained safety solution.
