    Default Proximity switches with optocoupler adapter

    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

    You can stack or AND opto outputs, but why do you need opto's?

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

    Hi,,, can someone people's by this forum, help to find me scheme wires of board optocoupler ? I have a picture only and the copper wires it's partially visible..
    I need use this optocoupler pcb for use with proximity sensors..

    I just wired my 3 wire PNP's to small relays I got from Radio Shack and that has worked great.

    I have already schematic 2530 IC. I need of pcb schematic copper wires for rebuild this board same to picture. I need know wires hidden under IC 2530. The two resistors value 33,000 ohms, it have a copper wires .Which are the linked pins IC ?

    It should be Very easy to reverse engineer?
    Use a meter to find common traces.

    Hello Al_the_man, I haven't the pcb physically, I need of build homemade and I have only pictures of this pcb. I need know of schematic wires . Can you find the non visible wires from picture? I need know as the two red resistors it's linked with whitch pins IC .

    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

    Here is a simple opto circuit using 4n35 etc.
    The 330 ohm resistor would need to be changed for higher input supply voltage.

    Hi my friend. After this time, do you have the complete schematic? I'm with the same problem.

    Thanks.
