Specification Features: The frequency converter interface (AVI+, AVI-) is isolated from the computer and the main control circuit, Strong anti-interference ability Support various versions of MACH3 software, support for the latest version. Support for Windows XP, WIN7, WIN8, WIN10, support for 64-bit systems, support for laptops, support for tablets. The external wide voltage input, 12-24V, and anti-reverse function. All the input signal isolation by the light lotus, can be accessed by emergency stop, the knife, limit, back to zero, etc., to ensure computer security. All the way through the optocoupler isolated 0-10V analog voltage output, you can control the input voltage from 0-10V analog voltage converter to control the spindle speed To provide PWM output (5V level), can be controlled by the PWM spindle control. Provide 4 output port (5V level), can be connected with the relay module optocoupler, water control, spray and so on. Can be accessed by a total of yang or common cathode, the input level of 5V, with optocoupler input stepper motor driver. To provide electronic hand wheel interface.
