Applicable to the stepper motor: 42,57,86-type phase current is less than 3A of the 2-phase 4-phase (4-wire line and 8 lines)

1. Maximum phase current output of 3.5A, the average output of 2.5A.
2. with spindle control relay, mach3, etc. easy to use software to control the start and stop of the spindle.
3. high speed optocoupler DC / DC fully isolated from the true sense of protecting your computer.
4. with 4-axis expansion, and convenience you require 4-axis machining, 4-axis extension.
5. Standard parallel port interface, support for MACH3, KCAM4 series software.
6. Supports four sub select - 1,1 / 2,1 / 4,1 / 16.
7. four input control, you can set the limit, stop, reset, which is divided into the knife.
8. support four operating modes - mixed-mode, fast mode, slow mode, the ordinary mode.
9. the semi-flow control functions, effective to stop the motor when the current drops to a minimum.
10. Have fan interface, you can add a fan to the board.

11. PWM chopper type sinusoidal micro-order control technology

12. pleasing in appearance, the cooling effect is good.

Dimensions: 154mm long * 132mm wide (pcb board size)   Size of the positioning hole: 143mmX122mm   Weight: 0.65kg (including parallel cable):

High-speed optocouplers and DC / DC circuit isolation, electrical isolation, rather than only the optocoupler false isolation. External current fleeing, it will not burn your computer, high-speed optocoupler 6N137 maximum transfer rate of up to 10MBit / S (ordinary optocoupler only a few KB transfer rate, it is easy to lose steps) to protect your computer while also ensure that the motor is not lost step, which is our drive and the market a lot of difference between one here to remind buyers at the time of purchase must be careful to do and burn your own computer is not worth the cheap little money.
