5.4.1 PCD3.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 modules are not suitable for low resistance
measurements like Pt 100, nor for thermocouples.
Module overview
PCD3.W200
8 channels for signals 0...10V

8 channels for signals 0...20 mA
PCD3.W220
8 channels for resistive temperature sensors Pt/Ni 1000,
other types of temperature sensors with resistances up to 2.5 kΩ
can be connected
