Do you want to implement more complicated safety functions with typical SIRIUS simplicity?
If so, the new 3SK2 basic units are exactly what you’re looking for. Unlike the proven 3SK1 safety relays which fail-safe shutdown is always triggered simultaneously for all outputs the 3SK2 relays, the fail-safe outputs can be disconnected independently.
The 3SK2 units can be easily parameterized using software. Because the fail-safe outputs can be used freely, during parameterization it is possible to specify the sensor/s that will act on each individual output/s when they are actuated.
More Highlights of the 3SK2:
Efficient semiconductor outputs adaptable to different loads by setting parameters
Simple implementation of muting and protective door monitoring with interlock
Simple commissioning and diagnostics, which simplifies the software if more critical safety functions are required
Do you need multiple safety functions for your plant concept that selectively shut down parts of your plant?
With 3SK2, there are two unit variants available for this purpose:
