6.8.1 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.
