The Industrial Raspberry Pi Forum

Hi all,

I want to connect a 3-wire PT100 on the analog inputs of a RevPi Compact, in order to use it through Codesys Runtime.
Can anyone please share a wiring diagram?

Thanks in advance

Hi

The RevPi Compact does only support 2 wire PT100 RTD, which must be connected to an input and it's 0V pendant. If the sensor is only available as 3 or 4 wire variant you could use an external temperature temperature transducer (converts the rtd to 0-10 V / 4-20mA)
