ABB AC500 V3 - Use of analog inputs as digital inputs; Connection of analog output loads (Voltage)

To avoid error messages from unused analog input channels, configure them as "unused".
Use of analog inputs as digital inputs
Several (or all) analog inputs can be configured as digital inputs. The inputs are not galvanically
isolated against the other analog channels.
The following figure shows the connection of digital sensors to the analog input AI0. Proceed
with the analog inputs AI1 to AI3 in the same way.

The following measuring ranges can be configured Ä Chapter 1.7.5.2.7 “Parameterization”
on page 815 Ä Chapter 1.7.5.2.9.1 “Input ranges voltage, current and digital input”
on page 828 :
Digital input 24 V 1 channel used
Effect of incorrect input ter-
minal connection
Wrong or no signal detected,
no damage up to 35 V
The function of the LEDs is described under Diagnosis and displays / Displays Ä Chapter
1.7.5.2.8 “Diagnosis and state LEDs” on page 821.
Connection of analog output loads (Voltage)
The following figure shows the connection of output loads to the analog output AO0. Proceed
with the analog output AO1 in the same way.
