Hi,
I am planning to use proximity sensors for my home and limit switches for Mach3. NPN NO sensors. They will be supplied by 24v going to a generic 5 axis board ( 5v)
Am I correct in thinking that means the black wire to the BOB from the sensor will also be receiving 24v, which will potentially damage what is a 5v board?
If thats the case should I not add a resistor somewhere to lower the voltage from 24v to near 5v to the BOB?
Any info or links most welcome.
Thanks.
