MACH3 CNC 5 Axis Interface Breakout Board For Stepper Motor Driver CNC Mill ST

product description This is a cost-effective, more powerful MACH3 interface board with the following features: 1, full support MACH3 and other support parallel port control of the computer software. 2, USB power and peripheral phase separation, to protect the computer security. 3, external wide voltage input, 12-24V, with anti-reverse function. 4, all the input signal through the optocoupler isolation, through emergency stop, knife, spacing and other ways to enter, to protect the computer security. 5, a relay output, you can control the spindle switch. P17 port output port. 6, all the way through the optocoupler isolated 0-10V analog voltage output, it can control the inverter through the appropriate analog interface to control the spindle speed. Output port to port P1. 7, all open 17 ports, can be connected with the drive optocoupler, 5-axis stepper motor control. 8, through the optocoupler input spindle governor control P1 PWM output. Full support for MACH3 and other computer software that supports parallel port control. USB power and peripherals are separated to protect your computer. External wide voltage input, 12-24V, with anti-reverse function. All the input signals are isolated by optical coupling, and can be accessed through emergency stop, knife, space, etc. to protect the computer. A relay output port that controls the spindle switch. P17 port output port.
