The SIRIUS modular system plays an important role when it comes to implementing safety-related applications. Our portfolio encompasses many other SIRIUS safety components, with which you can quickly and easily implement innovative safety solutions.

SIRIUS contactors can be directly controlled from failsafe controllers. In the higher power ranges, generally a coupling level was required due to the higher power consumption of the contactors. These new contactors with failsafe control input mean that this coupling level can be eliminated.

The F-PLC contactors represent a consequential continuation and development of the SIRIUS modular system in the domain of safety-related switching. Their failsafe inputs make it possible to achieve SIL 2 or PL c in accordance with IEC 62061 or ISO 13849-1 with just one contactor. SIL 3 or PL e can be achieved by connecting two contactors in series.

The huge advantage of this solution is that additional positively driven coupling relays can be eliminated, and the safety assessment process is made significantly simpler.

Safety Evaluation with TIA Selection Tool (TST) for Standards IEC 62061 and ISO 13849-1 allows you to quickly and simply assess the safety functions of your machine. The result is a report in compliance with the standard, which can be integrated into the documentation as proof of safety.
