    Thanks. I was also wondering now if anyone has an example of a loop. My senior designer is telling me I need a 4 wire Delta V input card and I don't know why. This is a micromotion 1700 coriolis flow transmitter with MVD technology.

    All of the other field powered loops I've done have only involved two-wire input or output cards.

    Am I confused or is he?

    I used quick reply in the original thread. Don't know why it didn't show up there.
