Hi. I have already bought 6 units of KC868-A4 model on Ali Express Order ID: 8154057463938467. There are 2 ports for 4-20mA. I have a TDS sensor output 4-20mA range 0-4400 us/ms.
Got 2 question.
1) Can you give a source code how to read from the 4-20mA port?
2) If my sensor signal 4-20mA to 0-5v is using 250ohm right? Can you show the diagram how to connect. Thanks.
My TDS sensor have a 3 wire (+, - & Signal (S1)).
