@fkarner Tak mam podłączone i odczyt wynosi ciągle zero

this works for me:

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.

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

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
