External wide voltage input, 12-24V, with anti-reverse function. Supports software versions including the latest release. Compatible with XP, Windows 7, Windows 8, Windows 10, 64-bit systems, laptops, and tablet computers. All input signals are optically isolated; emergency stop, tool setting, limit, and zero return functions can be securely connected to the computer. Inputs can be connected to a mechanical switch or a proximity switch (normally open with NPN). Optocoupler-isolated 0-10V analog voltage output allows control of 0-10V input inverters for spindle speed regulation. Provides PWM output (5V level) for connection to PWM-controlled spindle speed controllers. Includes 4 output ports (5V level) for use with optocoupler relay modules to control functions such as water cooling. Maximum output frequency of 100kHz; compatible with common anode or common cathode configurations. Input level is 5V, suitable for stepper or servo motor drivers with optocoupler input (pulse + direction). Features 5-pin interface cable socket (XH2.54) for easy connectivity. Product appearance, color, and printed markings may vary slightly between batches, but do not affect functionality.
