I went through my old PIC messages and can't find a reference to one, but I know I have seen one. I need to sense if a motor is still running (current through my relays on my PC board.) Someone must make a PC board mountable on/off sensor for AC current(1-10amps). I have seen hall effect switches mentioned, but can't find a source. This should be electrical isolated and will interface to my PIC. Thanks in advance. Steve ------------------------------------- E-mail: sdavidson@its.bldrdoc.gov Steven Davidson Dept. of Comm.
