Siemens 3RK1205-0BG00-0AA2 Safety Interface Module

Siemens 3RK1205-0BG00-0AA2 is a SlimLine AS-Interface Safety at Work safety interface module that provides two digital inputs (2F-DI) for mechanical sensors on an AS-i network. The S22.5F design uses spring-type terminals and a 22.5 mm-wide footprint, with IP20 protection suitable for industrial enclosures. As part of the ASiSafe family, this module functions as an input interface that translates safety sensor signals—such as emergency stops, safety interlocks, and two-hand control devices—into the AS-i safety bus, enabling safe-stop logic and monitored fault signaling. Key specifications include two fail-safe digital inputs, spring-terminal connection, and compatibility with Siemens’ ecosystem of AS-i Safety at Work safety modules. Typical applications encompass machine guarding and safety networks where a compact 2-channel input module is required, interfacing with AS-i masters and other 3RK1xxx safety components within a SlimLine installation. The module adheres to AS-i Safety at Work protocols for safe communication and is designed for seamless integration within Siemens’ portfolio of safety modules for easy maintenance and replacement.
