    I'm no engineer, but I'll take a look.

    Then ground loop hunting I will go.

    David_2, My shield is only grounded on the drive's PE terminal. This drains to the equipment ground. The drive is a ten horse ABB ACS800. The analog out that is "driving" the circuit is rated at equal to 700 or less ohms. I've connected a process calibration tool to the display I'm having...

    David_2, Thanks for the reply. I know I have the polarity of the loop wired correctly. So, I'm thinking the problem is with how the drive is grounded in comparison to how the loop is grounded. The only problem there is the only "grounding" of the loop is the cable (shield/drain) wire is...

    Greetings Smart Masses, Thank you for adding me to the community. I've become part of an unusual phenomenon involving an ABB drive and a IA1-D-VI analog input unit. Typically in a series circuit current stays the same and voltage drop across resistors changes based on E=I*R. I know this and as...
