Hi all,
Well, this is either going to be easy or impossible. I have a signal from a current transducer that produces a 0 to 5 VDC signal - 0 V when no AC current is detected, up to 5 V when it detects full scale AC amps. I want to use that voltage signal as an input to a motor controller, but I would like it changed from 5 to 0 VDC. That is, I want the full 5 V signal present when the transducer measures zero current, and zero volts present when the transducer has the maximum current through it.
Is there a simple circuit to do this? The controller has a +5 V pin, a signal pin, and ground for its voltage command input.
Thanks in advance.
