ABB AC500 PLC - Connection of Active-type Analog Sensors (voltage) with Electrically Isolated Power Supply to the Analog Inputs; Connection of Active-type Analog Sensors (Current) with Electrically Isolated Power Supply to the Analog Inputs

Connection of Active-type Analog Sensors (voltage) with Electrically Isolated Power Supply to the Analog
Inputs
The following figure shows the connection of active-type analog sensors (voltage) with electri-
cally isolated power supply to the analog input AI0. Proceed with the analog inputs AI1 to AI3 in
the same way.
Fig. 178: Connection of active-type analog sensors (voltage) with electrically isolated power
supply to the analog inputs
The following measuring ranges can be configured Ä Chapter 1.7.4.1.7 “Parameterization”
on page 897 and Ä Chapter 1.7.4.1.9 “Measuring Ranges” on page 909:
Voltage 0...10 V 1 channel used
Voltage -10 V...+10 V 1 channel used
The function of the LEDs is described under Diagnosis and displays / Displays Ä Chapter
1.7.4.1.8 “Diagnosis and State LEDs” on page 903.
To avoid error messages from unused analog input channels, configure them as "unused".
