Version 1.4
10.1.2 I/O card type 2
10.1.2.1 Analogue inputs
The I/O card is equipped with two completely independent analogue universal inputs:
One input is equipped with two channels.
10.1.2.2 Universal input
Channel 1 is used to process signals from RTD sensors, thermocouples, resistors, voltage sources
up to 1000 mV and current sources up to 20 mA.
The input type is selected via a parameter.
