Analogue input modules
5.8.2 PCD2.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.
