The analog signal to be measured is connected to the terminals AI 1+/- and AI 2+/-. AI stands for "Analog
Input". The CO "Current Output" and CI "Current Input" terminals supply the constant current for the 4-wire
measurement of PT100 elements.
Analog inputs
The module has two analog inputs. These can optionally be assigned parameters as voltage,
current or PT100 input.
Note
The analog inputs are only enabled following the parameter assignment.
Cycle time of the analog value accumulation: 20 ms per channel
