You can stack or AND opto outputs, but why do you need opto's?
Al.
I am replacing my MultiCam 22Plus CNC controller and some of the other parts with a Planet CNC controller.
My proximity switches for the three axis will require an "optocoupler" between the limit switch connection on the controller board and the proximity switch.
I have five proximity switches, 2 for "X axis", 2 for "Y axis", and 1 for "Z axis", My question is, can I wire the proximity switches for the two "X" switches in a series and the two "Y" switches in a series or does each switch require it's own optocoupler?
Thanks in advance

Thank you. My limit switches are PNP 3-wire units, not the mechanical type. The optocoupler adapter are not built in the controller.
There you go..

I just wired my 3 wire PNP's to small relays I got from Radio Shack and that has worked great.
can someone help to find me schematic diagram of this pcb?

Well the continuity test will tell you!
It looks like both 2.2k are fed off of the supply, pin 8, and each 2.2k are the load resistors on each output pin, 7 & 6.
It is a very simple circuit to R.E.

Thanks Al_the_man,, unfortunally I am not very prepared for theoretical electronics.
Can you put here a sample draw diagram of wires so I can understand ?
I have posted a two picture diagram the first is a IC 2530 optocoupler and the second as it will work with controller cnc and proximity swith limit..
thanks again

if this can help I have posted a schematic of 2530 IC
hello. someone can help me for solve this question ??
Here is a simple opto circuit using 4n35 etc.
The 330 ohm resistor would need to be changed for higher input supply voltage.
