IoT2040 Analog Input

Hi everyone,

I'm using a IoT2040 with the example image (node red v1.2.1) with the input/output module. I want to get data from a sensor with 4-20 mA output. By default, this node red version comes with "intel-gpio" nodes.

The documentation of the module explain that for I0 port the node port is A1, but all I get are values from 0 to 3 with no sense (the variations of the sensor doesn't affect the output values). Here are some images of the documentation and my connections. What can cause this error? Are other nodes more suitable for this problem? Thanks in advance!
