Re: Connecting PNP inductive proximity sensors to BOB
If the inputs are opto isolators with a internal series resistor set for 5v operation, you could simple measure the current the opto is set for by inputing 5vdc and measure the current, then wire a suitably calculated resistor in series from the collector to input based on the difference ~7v or just under.
Assuming open collector prox.
