I work on fix and upgrade of old industrial equipment and I would like to replace old logic board and relay logic by controllino. I need to measure temperature up to 250°C. this high temperature avoid using of DS18B20 or DHT digital temperature sensor. I want to use PT100 or K-type thermocouple for sensing temperature.
I want to avoid coversion to 0-10V because converters are expensive and internal ADC in controllino is only 10bit. I preffer solution with dedicated 12bit or better ADC.
Is there any DIN mount expansion modules for contollino which CE certification which allow to connect thermocouple or RCD sensor to controllino? I am looking for somethnig like IC max6675, but DIN mount package and CE certification is required.
