ABB AC500 PLC - Connection of Active-type Analog Sensors (Voltage) with no Electrically Isolated Power Supply to the Analog Inputs

Fig. 150: Connection of active-type analog sensors (current) with electrically isolated power
supply to the analog inputs
Current 0...20 mA 1 channel used
Current 4...20 mA 1 channel used
The measuring ranges are described in the section Measuring Ranges Ä Chapter 1.7.2.2.8
“Parameterization” on page 794
Ä Chapter 1.7.2.2.11 “Measuring Ranges” on page 802:
Unused input channels can be left open-circuited, because they are of low resistance.
Connection of Active-type Analog Sensors (Voltage) with no Electrically Isolated Power Supply to the
Analog Inputs
The following figure shows the connection of active-type analog sensors (voltage) with no elec-
trically isolated power supply to the analog input AI0. Proceed with the analog inputs AI1 to AI3
in the same way.
