The way I understand this is that I should be able to wire all the limit switches in parallel to one input on the computer. I would use indicator lights to let me know which limit has tripped the machine. Then I will use three inputs for the X/Y (dual X, one Y) home location. Since these are digital inputs and not anylog I should be able to use relays that the prox sensors will close and the common/NO pins on the relays for the input to the computer. Am I correct in my thinking?
