Description
The FoxAlien PWM Smart Relay Module is designed for controlling the CNC add-on such as FoxAlien VFD Spindle and vacuum cleaner when using the CNC machine. It can also work with the laser engraving module and air assist pump. It can allow the controller to turn on/off those add-ons automatically.
I find having this item to be very handy. I mainly use it when I have my 40W Laser on my CnC. I love the fact that it turns on the Air Assist automatically
