The Siemens 3RK3611-3AA00 is a SIRIUS diagnostics display for the modular safety system 3RK3 (MSS). It provides a local HMI for reading system diagnostics and acknowledging faults on the safety bus, with 4 keys for navigation and input, a single display screen, and 3 status LEDs for quick visual indication of system health.
The module measures 96 mm wide by 60 mm tall by 33 mm deep, and mounts via screw fixing in a vertical position. The front face carries an IP54 rating, meaning it is protected against dust ingress and splashing water from any direction — suitable for panel doors in industrial environments where occasional washdown or condensation is expected. Installation altitude is limited to 2,000 m above sea level without derating.
