SIL 2 VSD

Rob Eagle
Anyone know who else does Variable Speed Drives (VSD), other than the Siemens (G120), that can contribute to a SIL 2 safety function?  Even better if they have EMPHASIS certification as well.  Looking for a 7kW drive.


By the way BS EN 61800-5-2 refers to them as PDS(SR)s.


Thank you.

    Hello Rob,


    Could you give some more details about the application please? You could use almost any VSD as part of a SIL2 safety function depending on how it was implemented. The Siemens G120 has some additional intelligence in the control unit I think, I don't know the model well though.
