MAX31855 with multiple thermocouples

[slepax]

Hello all,

First time poster here!

I am using MAX31855 to read and digitize temperature readings from a K type thermocouple.

Eventually my project will require several thermocouples (about 4-5) and I was wondering if I must use separate MAX31855 for each thermocouple?

Or maybe it is possible to use a common ground between all thermocouple and switch between them (using a solid-state relay) just before the reading?

Thanks
Ron
