I have a signal coming from a peice of equipment that when ON sends 12V to a computer and when off 'sends' 0V.
I replaced the equipment with a newer version that works the oposite way around. So that when ON is have a 0V signal and when OFF the signal is 12V
I can not modify either system. Only add somthing in between that will convert it to what I need.
What is the easiest way to take that 12V signal and make it 0V and when its at 0V make it 12V?
I know I can do this with a signal throw relay, but they are large and might not be the best way. Or maybe it is ?
