PCD2.W2x0, analogue inputs, 8 channels, 10 bit resolution
Application
With its short conversion time of <50 µs, this module is universally suitable for
recording analogue signals. The only limitations are with weak signals, as with
Pt 100 resistive temperature sensors, or with thermocouples.

the other channels are significantly falsified.
