Question #: 13976

Question: What is the relay coil on the USB motion card for?

Current Solution

A 24V connection to the USB motion card is only needed if you are using limit switches (inputs), powering the spindle/VFD speed and direction, and for the outputs, for powering other devices (mist, coolant, etc.).

If you are using a VFD (Variable Frequency Drive, also called Inverter) for a spindle, they typically have a 24V out terminal that can be used with our USB motion card. If you are not using a spindle/VFD (we highly recommend one), then you will need to purchase a 24v power supply to power that side of the board.

The outputs mentioned above are to connect to external devices and will require a relay (a mechanical switch that is controlled by a digital signal). This mechanical switch can turn on a device like coolant and mist, or even a router, if you are using one. A relay is required to turn on these devices because the devices are typically higher voltage, like mains (110v or 220v). So, a relay can turn on or off a high voltage device with a lower voltage (24v) signal.

  • Breakout Board with Relay. What is the USB connection on this board for? Does this board Still require a 5v power supply?

    We generally use the USB to power the interface (breakout board). The current from the computer is sufficient to supply the breakout board.

  • The relay doesn't have a A+ B - it has signal in god. 5v. / 0 S P. This has to go to my USB motion card wiring shows v+ goes to top of coil no number and comes out the bottom to #2 the relay I got from you is not that simple

    The relay is only used for devices like routers, spindles, coolant, mist, etc. The relay works like an automatic switch and will allow current to pass when the relay is engaged.

  • What relay should be used with your USB BOB for controlling mist/flood/spindle on/off?

    The relay that should be used with your USB BOB for controlling mist/flood/spindle on/off is one of the following options.

    You could get and use the Planet-CNC.com Output Board found here, http://www.planet-cnc.com/index.php?page=shop

    Or you could create your own setup using a resistor, solid state relay, transistor, and diode. You can watch this video, https://www.youtube.com/watch?feature=player_embedded&v=PJO_XoLL6lQ, to find out the correct way to accomplish this.

  • What functionality is lost if 24V power supply not provided to "Mach3 USB Motion Card"?

    If the Mach3 USB does not have a 24V power on the limit switch/output/DAC side of the board, then those functions (limit switches, outputs and the DAC) will not work. If you have a spindle, you can use the 24V output from the VFD (Variable Frequency Drive) to serve as the 24V supply.
