5.7.2 PCD2.W11x, analogue inputs, 4 channels, 12 bit resolutionPCD2.W11x, analogue inputs, 4 channels, 12 bit resolution

for resistive temperature sensors Pt/Ni 100, 1000

High-speed, convenient module for recording absolute temperatures in the range

-50 ... +150 °C or +350 °C (W114) using a resistive temperature sensor. (2-wire

connection with zero adjustment) The temperature curves are linearized in the

module itself. The resolution is 12 bits.
