PT100 / PT1000 Inputs
Note: RTD inputs works only as pair (A0A1, B0B1, …). If A0 for example is to be used and A1
not, then A1 need to wire bridged.
Function: Reading a resistance/ temperature value (v1.0.8 and older)

Conversion at port of a resistor in Ohm
Formula: Resistance in Ohm = Value / 100
Example: Value = 100000 corresponds 1000Ohm
Conversion at port of a PT1000 temperature sensor to °Celsius
Formula: Temperature in Grad Celsius = (Value / 100 -1000) / 3,891
Example: Value = 112000 corresponds to +30,84°Celsius
Value = 100000 corresponds to 0°Celsius
Value = 90000 corresponds to -25,5°Celsius
