ai 801 module generating mA.
I have 5 AI cards attached with ac 851 controller. The problem is every channel of each ai 801 module generating mA signal of around 100 mA instead of accepting any signal, even if the signal from field is 7 mA. I disconnected all the wire from channel even then its generating around 98 to 100 mA. As soon as i am closing the TB it doesnt show the corresponding scaled value in software, it only shows the maximum value 100 as i have set the range 0 to 100. Channel type selected is 4-20 mA. What can be the problem?
