ABB AC500 V3 - Connection of active-type analog sensors (Voltage) with no galvanically isolated power supply to the analog inputs

Fig. 78: Connection of active-type analog sensors (current) with galvanically isolated power
supply to the analog inputs
The following measuring ranges can be configured Ä Chapter 1.6.3.1.1.6 “Parameterization”
on page 565:
Current 0 mA...20 mA 1 channel used
Current 4 mA...20 mA 1 channel used
The function of the LEDs is described under Diagnosis and displays / Displays Ä Chapter
1.6.3.1.1.8 “State LEDs” on page 572.
Unused input channels can be left open-circuited, because they are of low resistance.
Connection of active-type analog sensors (Voltage) with no galvanically isolated power supply to the
analog inputs
The following figure shows the connection of active-type analog sensors (voltage) with no
galvanically isolated power supply to the analog input AI0. Proceed with the analog inputs AI1 to
AI3 in the same way.
