Connection of a resistance measuring bridge with external supply. 1 analog sensor requires 2 channels.

All voltage measuring ranges can be configured AI531 Analog Input Module AI531 Analog Input Module .

The calculation of the resistor deviation must be performed via the bridge voltage by the PLC user program.
