Features: Support various versions of MACH3 software and support the latest version. Wide external voltage input, 12-24V, and anti-reverse function. All input signals are isolated by optical diaphragm, which can be connected to emergency stop, tool setting, limit position, 0 return, etc. to ensure computer security. The input can be connected to a mechanical switch or a proximity switch (to be normally opened with NPN). One-way optocoupler-isolated 0-10V analog voltage output can control the inverter input from 0-10V analog voltage to control the spindle speed. PWM output (5V level) is provided, which can be connected to the spindle governor controlled by PWM. Provide 4 output port (5V level), which can be connected with photocoupler relay module to control water cooling, spray and so on. Maximum 100KHZ output per axle, can be connected to common anode or common cathode, input level is 5V, stepper with optocoupler input or servo motor driver (pulse + direction). Provide 5-axle interface cable socket (XH2.54) for easy connection. Provide an electronic handwheel interface,the board prints all port names, at a glance. Drive output type, strong anti-interference ability, long-distance transmission. Applications: CNC machine tools, printing machinery and other 0 correction and signal segmentation.
