I2C 1-Channel 4-20mA

Software
1

I have tried multiple python scripts to get the output of this to come across to a Raspberry Pi 4. I am using the i2c shield from NCD with the PR33-7. If I disconnect power from the signal generator, the output goes from ~1.5 to ~-4.75. Adjusting the output of the signal generator does not change the signal generated.

If someone could point the way to how to read this from python, I would appreciate it.

Hi,
this product provides the loop supply so there is no need of external supply to power up the sensor.

make sure you are using the ADC in single ended mode
