Fig. 90: Connection of active-type analog sensors (current) with galvanically isolated power
supply to the analog inputs
The following measuring ranges can be configured
Chapter 1.6.3.1.2.6 “Parameterization”
Chapter 1.6.3.1.2.9 “Measuring ranges” on page 606
Current
0 mA...20 mA
1 channel used
Current
4 mA...20 mA
1 channel used
For a description of the function of the LEDs, please refer to Diagnosis and displays / Displays
Chapter 1.6.3.1.2.8 “State LEDs” on page 606
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.
