How to connect two-wire current converters?

FAQ #100623

The analogue input modules for current inputs can be used together with four-wire current converters and also with two-wire current converters.


How to connect a two-wire current converter?
Usually 2-wire current converters (0..20 mA or 4..20 mA) are to be supplied with 24V. The converter itself will then limit the current according to the unit to be converted.
For this system to work the wiring scheme below needs to be applied. Note that the converter is serially connected to the input module.


Never connect the 24V directly to the input of the analogue input module because this could damage the input module!
