SIRIUS 3RK3 Modular Safety System

Flexibility and functionality in a new dimension

Whether you are looking for a simple solution or a complex safety application:

With our SIRIUS 3RK3 Modular Safety System (MSS), you can rely on a universal modular system that enables you to adapt machines and plants in the most flexible and economic way – both for new designs and for retrofits. Because safety functions can be parameterized quickly and easily using the MSS ES software.

Thanks to the consistent modularity, you are also extremely flexible within your applications and save costs since you do not have to utilize more modules than necessary. The SIRIUS 3RK3 Modular Safety System can be applied for safety applications up to SIL 3 according to IEC 62061 and PL e according to ISO 13849-1 respectively.


The SIRIUS 3RK3 modular safety system's new central unit makes it easy to supplement expansion modules. An AS-i interface has also been integrated into the new central unit, significantly simplifying cabling. In addition, the DP interface module allows the MSS system to connect to higher-level plant controllers via PROFIBUS.


Modular system for customized solutions

The Basic, Advanced and ASIsafe versions of the central modules represent the core of our SIRIUS 3RK3 modular safety system, whose number of inputs and outputs can be flexibly adjusted via expansion modules or AS-Interface. This allows for the quantity structure's flexible adjustment to the respective application. In addition, an interface module facilitates the transmission of diagnostics and state data to a superior PROFIBUS network. The MSS ES parameterization software forms a central system component and supports the rapid and easy parameterization of safety functions as well as comprehensive diagnostics options.
