Connection of active-type analog sensors (voltage) with electrically \ isolated power supply

Standard ranges

Connection example

The measuring ranges can be configured AI531 - Analog Input Module AI531 - Analog Input Module:

Voltage	-50 … +50 mV	1 channel used
Voltage	-500 … +500 mV	1 channel used
Voltage	-1 … +1 V	1 channel used
Voltage	-5 … +5 V	1 channel used
Voltage	-10 … +10 V	1 channel used
Voltage	0 … +5 V	1 channel used
Voltage	0 … +10 V	1 channel used

Common mode range (+/-20 V)

Connection example

The measuring range can be configured AI531 - Analog Input Module AI531 - Analog Input Module:

Voltage

Common mode voltage

1 channel used

The function of the LEDs is described under Diagnosis and displays / displays AI531 - Analog Input Module.

In order to avoid error messages or long processing times, it is useful to configure unused analog input channels as “unused”.
