Hi all. I'd like to replace the mechanical home switches on my 6' X 20' Mechmate with inductive proximity sensors, using Mach3 scheme of all switches into one input. I know I can drive mechanical relays with the prox switches but I'd prefer to not use the mech relays.
Anyhow, I'm searching for a scheme that will allow me to tie the prox sensors into a single opto isolated input on my control card. The sensors are PNP N.O., 10-30VDC. The opto input, with my limited understanding, seems to be looking for a simple switch, not an external voltage or current signal. Voltage between the input pins is approx 3.5 volts.
Sure would appreciate some direction on this.
Thanks, Chuck
