Hi eevblog,
I've lurked for a long time, but I finally got around to making an account to ask a question. I have a basic understanding of A to D and D to A converters, sample rate, bit depth, Nyquist frequency, etc.
I'm using an Allen Bradly compact logix plc, and my plc has what's described as four "Universal Analog Input Points", each point having a terminals labeled "V in" "I in" and "V/I in".
Can someone explain to me the function of each terminal? I've tried my best to hunt through the pdf's provided by Allen Bradly but I simply can't find what I'm looking for.
Thanks in Advance.
