Product Details

SIRIUS 3RK3 Modular Safety System - Advanced 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 Advanced Central Unit

The SIRIUS 3RK3 advanced central unit is the logical expansion of the basic central unit, with the functionality of the AS-I safety monitor. It enables a standard AS-i network to be upgraded for safety related tasks. Typical applications of this safety relay are slave-to-slave communication in modular machine concepts or safety related communication with plant components. In addition to the features of the Basic version, the 3RK3 Advanced central unit offers numerous additional features.

1 AS-i connection
8 safety-related inputs
1 safety-related relay output
1 safety-related solid-state output
Up to 9 expansion modules can be connected
Expanded cyclic data exchange via PROFIBUS: up to 64 bit
More flexibility Signals can be read in via central inputs or AS-Interface
Reduction of wiring overhead
Simplified collection of sensor signals in extensive plants via AS-Interface
Slave-to-slave communication via AS-Interface, i.e. data exchange between several central units
Distributed shut down of drives via AS-Interface
