I need to replace an obsolete thermocouple and RTD mux system. There are four of these with 32pt each. Three of them are T/C and one is RTD. The mux's are installed outside in a fairly harsh environment. Conformally coated would be preferable. I would like to go with some type of modbus TCPIP setup where I can pull the data back to a server and then push it to my DCS. Anybody used something like this before that worked well.
