    If anyone could help, I would GREATLY appreciate it!

    I am trying to get 0-10vDC from an AC drive's analog output of 4-20mA signal.

    I thought that all I would need to do is put a 500 ohm resistor in series with the output and be able to get this, but it is not working.

    I have also tried putting the resistor in parallel and am having no luck.

    Can anyone help with this?

    Hi cavery

    Your statement: I am trying to get 0-10vDC from an AC drive's analog output of 4-20mA signal.

    The circuits I have seen use operational amplifiers for this purpose.

    Here is a site which contains a schematic of a current to voltage converter.

    I hope it gives you some ideas about how to design your converter.
