FAQ
How do I configure the time delay on the 3SK1213-1AB40?
The time delay is not configurable on this specific model. The 3SK1213 series are basic units with fixed functionalities. For adjustable time delays, you would need to look at other models in the SIRIUS 3SK1 Advanced or 3SK2 series, or use an additional timing relay.
Can this safety relay be used for a SIL 3 / PL e application?
Yes, the Siemens SIRIUS 3SK1 relays are certified for use in safety applications up to SIL 3 according to IEC 61508/IEC 62061 and PL e according to ISO 13849-1. Always consult the official safety manual and perform a proper risk assessment for your specific application.
What is the difference between the instantaneous and delayed outputs?
The instantaneous enabling circuits switch immediately when the safety conditions are met. The delayed enabling circuits switch off after a set time delay when the input signal is removed, which is useful for applications like allowing a motor to come to a controlled stop before the power is completely cut.
