  • Click C0-02DR-D 4-20mA input

    Just to make sure. I have a 2-Wire 4-20mA instrument. Is this correct for the wiring:

    Supply Ground to Click's ACOM (Analog common)

    Supply +24 DC to instruments "+"

    Instruments "-" to Click's AD1I or AD2I

    I want to say that is exactly what the manual shows. It isn't "exactly."
    Why I quote "exactly" is:
    The CPU manual doesn't indicate transmitter polarity.
    The Card manual marking show CH1... Not AD1I or AD2I

    So pete, it looks correct.

      The analog input module is pretty clear, it was the illustration for the CD-02DR-D in c002drd.pdf that didn't show a 2 wire 4-20mA.
