Connection of a resistance measuring bridge with external supplyΒΆ
With the connection of a resistance measuring bridge with external supply, the supply voltage is provided separately.
The following figure shows the connection of a resistance measuring bridge with external supply.
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.
