    Hi mic3, no i get a 20v + from a controller,in opperation it goes to a air
    transducer that gives me the 4 to 20 mA signal out. the controller displays
    that signal as air pressure. i am building a simulator to test the controllers
    out of opperation. therefore i nead to vary the 4 to 20 mA to get different
    pressure readings.
