1 analog load requires 1 channel

The following measuring ranges can be configured Analog Input/Output Module AX521 Analog Input/Output Module AX521 :

Voltage -10 V…+10 V Load max. ±10 mA 1 channel used
Current 0…20 mA Load 0…500 Ω 1 channel used
Current 4…20 mA Load 0…500 Ω 1 channel used

Only the channels 0…3 can be configured as current output (0…20 mA or 4…20 mA).

The function of the LEDs is described under Displays Analog Input/Output Module AX521.

Unused analog outputs can be left open-circuited.
