For the measuring ranges that can be configured, please refer to the sections Measuring
Ranges
Ä Chapter 1.7.1.2.10 “Measuring Ranges” on page 731 and Parameterization
Ä Chapter 1.7.1.2.7 “Parameterization” on page 721.
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.
