Description
Pt100 sensor connected to a standard analog input selected
by parameter 35.24 Temperature 2 AI source
output.
The following settings are required:
• Set the hardware jumper or switch related to the analog
input to U (voltage). Any change must be validated by a
control unit reboot.
• Set the appropriate analog input unit selection parameter
in group 12 Standard AI
• In parameter group 13 Standard
selection parameter of the analog output to
excitation.
The analog output feeds a constant current through the
sensor. As the resistance of the sensor increases along with
its temperature, the voltage over the sensor increases. The
voltage is read by the analog input and converted into
degrees.
As selection 1 × Pt100 analog
connected in series. Using multiple sensors improves
measurement accuracy significantly.
