Temperature monitoring using Pt1000 sensors
1…3 Pt1000 sensors can be connected in series to an analog input and an analog
output.
The analog output feeds a constant excitation current of 0.1 mA through the sensor.
The sensor resistance increases as the motor temperature rises, as does the voltage
over the sensor. The temperature measurement function reads the voltage through
the analog input and converts it into degrees Celsius.

Temperature monitoring using Ni1000 sensors
One Ni1000 sensor can be connected to an analog input and an analog output on the
control unit.
The analog output feeds a constant excitation current of 9.1 mA through the sensor.
The sensor resistance increases as the motor temperature rises, as does the voltage
over the sensor. The temperature measurement function reads the voltage through
the analog input and converts it into degrees Celsius.

Temperature monitoring using KTY84 sensors
One KTY84 sensor can be connected to an analog input and an analog output on the
control unit.
The analog output feeds a constant excitation current of 2.0 mA through the sensor.
The sensor resistance increases as the motor temperature rises, as does the voltage
over the sensor. The temperature measurement function reads the voltage through
the analog input and converts it into degrees Celsius.
