The area is a Zone 2 and requires an ATEX rated instrument. We requiredigital switchfor low level blanket, high level blanket and instrument health. There is 24VDC and 230V power supplies available. I am not a process engineer, I am a M & E Commissioning Engineer. I would appreciate help and advice on product selection. Many thanks for reading this thread.

I think it is n longer promoted but still available. Bus companies used to delete the last bus from timetables and then no one waited for the bus the lack of use was used as an excuse to withdraw the service.
