Procon Electronic's(https://www.proconel.com/product/pt8...dule-isolated/)We use this, I did not set it up so I don't know what all you can do but we pull over ethernet 8 TC values to our scada system. Also Check out (https://www.mccdaq.com/temperature-measurement.aspx)CBCOM CB-7018 we use to use it, it is RS-485, they have units with more than 8 channels, and other devices that do similar function, again I did not setup so I don't know what all you can do. Also pyromation has devices, we called puck transmitters for temp sensor thermocouples and RTD's etc.
