Plc5 sil?

Hi everyone

Does anyone know what SIL are the PLC5 I/O cards? If I have a pressure instrument which is SIL2 (guarantees the safe fail) connected to PLC5 1771-IFE card, is it still SIL2? Is the 1771-IFE safe fail also?

Thank you!

Remember, its friday!

I don't think 1771 modules have passed any SIL qualifications.

The whole system will not be SIL certifiable if one component isn't.

I fail to see how you can look at an analogue input card to a plc and consider the PLC can be used for a safety application.
this is not safety rated
