I have existing equipment that uses both Sinking and Sourcing Sensors. The new control hardware I'm putting in is Sinking only. Is there a circuit that I can use to allow me to use both input devices? I know I can use a pull up resister, but 1. I have to only install it on the devices that need it and 2. It inverts the signal which is not good for photo eye logic.
I know that at one time AB had a circuit inside their I/O that would accept either type of input automatically.
Does anyone either have a schematic of that circuit or a similar one?
Thanks!!!!!
