Assignment of the possible sensor types to the inputs
In the case of voltage measurements (max. 3.3V), note that the internal resistance of the voltage
source must not exceed 100 ohms otherwise the accuracy will be less than that specified in the tech -
nical data.
Resistance measurement: If the process variable is set to "Dimensionless", measurement is only
possible up to 30 kΩ. If the process variable is set to "Resistance" and the resistances being meas -
ured are >15 kΩ, the averaging time should be increased as the values will fluctuate slightly.
Resistance table for various sensor types
The standard type used by Technische Alternative is PT1000.
KTY (2 kΩ) was the factory-fitted standard type until 2010/2011.
PT100, PT500: As these sensors are more susceptible to external interference, their sensor leads
must be screened and the Average time should be increased. Nevertheless the accuracy specified
in the technical data for PT1000 sensors cannot be guaranteed.
