Connection of a PT100 temperature sensor uses four analog inputs.
This configuration allows you to connect up to one PT100 temperature sensors:
-AIN1 & AIN2 (100R reference resistor)
-AIN3 & AIN4 (current )
-AIN2 & GND (measuring PT100)
And it's possible to connect one additional sensor on the analog input which has an
output up to 2,5Vdc.
-AIN5 & AIN6 (either differential or single ended)
And it's possible to connect up to two sensors on the analog input which have an
output up to 3Vdc.
-AIN7 & GND
-AIN8 & GND
Please note that AIN7 and AIN8 can be used to connect sensors which have a slightly
higher voltage output up to 3Vdc (Like our UVS sensors)
An example how to configure the software. (which will be explained in chapter 14)
