    hi all,
    At my project i try to drive a stepper motor via plc. I built a driver card and can generate pulses approximately 200 pps but the out put of plc is 24V and i need 5v to put in my driver card. How can i regulate it? does anyone have scheme?
    Thanks in advance

    You could put a Buck converter chip to regulate the voltage for the driver card... How much amps the card uses?

    You need to post schematics of your circuits so that we know for certain what you are talking about. This eliminates most confusion, and helps you to get a speedy and accurate reply.

    Please post your schematics in .PNG format, as that format is compact and not "lossy" like .jpg is. Use the "Go Advanced" and "Manage Attachments" buttons to upload the images from your computer to the board.

    you could do a clamp using a zener diode rated for somewhere near 5V - i would suggest under - 4.7V is a common value if i remember right - and will be interpreted properly.

    but schematics would be a great first step.
