        If your current sensor already has an external power supply, the jumper cap is connected as shown on the bottom
        If your current sensor does not have an external power supply, connect the jumper cap as shown on the top, and connect the interface of AIN4-20mA

          @robski Yes or not. This is a publicly available manual. It is unreadable to me. This circuit that I drew does not work correctly.

            @Kris if your sensor needs power supply like you drew it then it has to be connected to 24/gnd pins of module , sensor to IN and then you need to use 3 jumper setup not the one marked red on your picture

              Hi @Kris

              From my point of view it should work. Some time ago, I connected the AIN module with a pressure sensor according to this scheme:

              Works well in my case.

                @fkarner Tak mam podłączone i odczyt wynosi ciągle zero

                  @Kris what you see on multimeter (mA) in place of AIN module? Any values in range of 4-20mA?
