MACH3 Control board (V2.1)  Only support LPT win xp computer,not support win7/8/10

Features:

1. There are 3 replays, P2, P3 and P4, which can support MACH3 control software programming. The relay's on or off can be controlled through the control of MACH3 software. Each relay has attracted indicating lamp, which is more intuitive and convenient. The 3 relays can be used to control the opening and closing of the liquid coolant, mist coolant, liquid state coolant and so on. They can also be used to control  the electromagnetic valve device power switch. P2 port is for the spindle, P3 port is for the cooling liquid, P4 port can be defined.

2. The high speed optical coupling isolation is used to control the rotational speed of spindle. The output port is parallel port P1, which can output the PWM signal within 2.5KHZ. On the interface board ,there is a D/A circuit, with PWM to a 0-10V. The circuit can output 0-10V level to control the inverter which only has analog speed control in the market. Thus it can control the rotational speed of the spindle. It is important that the PWM output and 0-10V output can only choose one in two. They can't be used at the same time.

3. Interface board can be connected with the cathode or total output to the stepper drive, or servo drive (servo driver must support the digital signal).The output is the 5Vlevel.

4. Wide input voltage power supply: 15-32VDC. The function of preventing reverse connection protection. 2 groups of output voltage: 5V and 12V voltage, 100MA output capacity.

5. Power supply voltage has a wider range: 15-50VD

Increase isolated power module. Do not insert the USB line to the computer's USB port. Just insert a LPT line. It is more convenient and reliable.

The current output ability of 5V and 12V voltage output can upgrade to 200MA.
