Are there any specific standard requirements for the relays configured in the SIS system? Is a regular relay sufficient, or is a safety-rated relay needed, or one with a SIL rating certified by TUV?

Theoretically, there should be an SIL level assessment

It is recommended to take a look at Document No. 116 on work safety supervision.

Does the so-called SIS truly meet the SIL level for the entire circuit? If that’s satisfied, what about routine maintenance?
