Sirius 3RK3 modular safety system users can connect to seven expansion modules, allowing the system to keep up with the safety needs of changing applications.
Siemens Automation and Drives has released the Sirius 3RK3 modular safety system.
Developed to sit alongside existing Siemens safety integrated solutions, ASi Safe or ProfiSafe, the Sirius 3RK3 system offers increased choice for what can be complex safety application decisions.
Sitting between a simple safety relay and a fail-safe controller, Sirius 3RK3 is suitable for use across all sectors and applications.
It is suitable for circumstances where several safety functions have to be evaluated, but expensive connection of several switching devices could prove cost prohibitive and time consuming.
The Sirius modular design offers application flexibility as users only have to replace the devices applicable to that application.
However, if the application does change over time, more functions can be added to the modular unit.
The system is based on a central unit with eight safety-related inputs, one safety-related relay output and one safety-related solid-state output.
Users can connect to seven expansion modules that can deal with further safety functions and an interface module enables communication to additional higher-level controllers via Siemens Profibus.
