ABB AC500 V3 - Connection of a resistance measuring bridge with internal supply

Fig. 46: Connection example
The following measuring ranges can be configured Ä Chapter 1.6.2.2.3.6 “Parameterization”
on page 472 :
Resistor 50 kΩ 1 channel used
For a description of the function of the LEDs, please refer to Diagnosis and displays / displays
Ä Chapter 1.6.2.2.3.7 “Diagnosis” on page 475.
In order to avoid error messages from unused analog input channels, it is useful to configure
them as "unused".
Connection of a resistance measuring bridge with internal supply
When resistance measuring bridges are connected, the short-circuit-proof voltage output
(internal supply) at pin I0A (or I2A, I4A, I6A) must be used. This supply voltage is activated
as soon as "Voltage Measurement" is configured for the relevant channel.
