1 analog input requires 1 channel

The following measuring ranges can be configured Analog Input Module AI523 Analog Input Module AI523

Current 0…20 mA 1 channel used
Current 4…20 mA 1 channel used

The function of the LEDs is described under Displays Analog Input Module AI523.

Unused input channels can be left open-circuited, because they are of low resistance.
