Features of CNC adapter:
1) A parallel management port for software support that fully supports Mach3.
2) For the safety and protection of the computer, phase separation power is also used, as is USB power with other peripheral devices.
3) Has a peripheral wide input voltage range of 12-24 V with anti reverse function.
4) All the cords are insulated; when an alarm signal is input, you can stop it using the switch. This is part of protecting your computer.
5) The entire path passes through an optocoupler. The isolated analog output has a 10 V voltage that can be controlled using an analog interface converter to control the spindle speed.
6) You can open all 17 ports that can be accessed with an optocoupler. 5 axis stepper motor can be adjusted using ports.
7) P1 PWM outputs can be controlled with opto-isolated spindle input.
8) Can be accessed with a common cathode or common anode. With an input level of 5 V drive.
