SIRIUS 3RK3 Modular Safety System - Basic Central Unit

The SIRIUS 3RK3 modular safety system (MSS) is a freely parameterizable modular safety relay. Safety oriented applications up to Category 4 according to EN 954-1, Performance Level e according to ISO 13849-1 or SIL3 according to IEC 62061 can be reached depending on the external circuit version. The modular safety relay enables the interconnection of several safety applications. The comprehensive error and status diagnostics provides the possibility of finding errors in the system and localizing signals from sensors. Plant downtimes can be reduced as the result.

3RK3 Basic Central Unit

The SIRIUS 3RK3 basic central unit is used wherever more than three safety functions have to be analyzed and where parameterizing the wiring of safety relays would be time consuming and expensive to implement. This safety relay reads inputs and controls outputs and communicates with higher level controllers via an interface module. The entire safety program of an application is processed in the central unit. At the smallest configuration level, the 3RK3 Basic central unit is already functional without the expansion modules that can be connected as options.

8 safety-related sensor inputs
1 safety-related relay output
1 safety-related solid-state output
Up to 7 expansion modules can be connected
Cyclic data exchange via PROFIBUS: up to 32 bit
High flexibility and reliability of planning thanks to a modular design
More space in the control cabinet and lower costs thanks to a highly modular quantity structure
More functionality and time saving through a parameterizable software system
Extensive diagnostics on site and project documentation using the MSS ES software
Improved plant diagnostics and higher plant availability through data exchange via PROFIBUS

Siemens Safety Controller

The comprehensive error and status diagnostics provide the possibility of finding errors in the system and localizing signals from sensors resulting in the reduction of plant downtimes. Its basic central unit is used wherever more than 3 safety functions have to be analysed and parameterizing the wiring of safety relays would be time-consuming and expensive to implement. This safety relay reads inputs along with controls outputs and communicates with higher-level controllers via an interface module. The entire safety program of an application is processed in the central unit. At the smallest configuration level, the 3RK3 basic central unit is already functional without the expansion modules that can be connected as options.
