Digital Analog I/O peripheral
2.4.1 Board Power supply
The card reads as feedback only the voltage of the PT1000 side galvanically insulated.
It does not detect the lack of power supply circuits for input / output, so you need to power through
terminals M1 or M2, galvanically insulated side from the micro.
