I have a question using markvie pdio card
How to pdio recognize digital input
For example limit switch , pressure switch
Our digital input voltage is 125vdc wetting system
When i check the voltage the pdio terminals, but i always check the + 62.5vdc, -62.5vdc even if the switches are off
Then how can pdio recognize the digital input "true"
