The Industrial Raspberry Pi Forum

Hello!
I am using my MIO extension for my RevPi Connect S
I have one analog input which i have put 5 volts on. The value in the computer is around 5000 then.
However, when i put a high 24v dc on digital input 1 in the X2 connector, the analog value becomes 10744. Eventhough only 5 volt is on the analog input pin. When i remove the 24 v signal from the digital input, the analog value goes back to around 5000.

What is happeing?

Thanks in advance!
Jonathan

Hi Jonathan

How is the digital ground wired?

Hello, the MIO module is grounded to yellow/green earth through the wall outlet. What do you mean with the digital ground?
