Features:Support all versions of Mach3, including the latest version. Fit for all Windows versions. USB does not require drivers, all are plug and play, and hot plugging is supported.USB bus uses high-end chip magnetic coupling isolation, truly valuable isolation, different from the optocoupler isolation of the general control card.Input and output, to achieve ultra-reliability, absolutely guarantee the safety of computer USB. At the same time, it guarantees superior electro magnetic compatibilityimmunity.Single-chip, the system is more streamlined, and the stability of the multi-chip processing is much higher than the average.Dual-core ultra-high-speed CPU (single core with a maximum frequency of 204MHz), the processing power is extremely redundant. And to ensure the 3K axle linkage 1000KHz pulse output frequency, 4 axle linkage 750KHz pulse output frequency, 6-axle linkage pulse output frequency up to 500KHz, can be connected to servo / step.The size of the motion control buffer can be set to ensure stable operation during the fastest interpolation cycle, and it can run smoothly when the computer is overloaded.With 16 isolated input port, the input interface is simpler, the port are wet and dry contacts, and the wiring is simpler. The dry contact method only needs to connect a physical switch to the ground line externally. All 16 input port have signal indication. When the indicator is low, the indicator is on and the debugging is simple and clear.Has a maximum of 24 output port (8 channels, RS485 can be expanded), 32 input port(with 16 input, RS485 can expand 16). PWM speed control output port (isolated), PWM frequency can be set, duty cycle 0~1000 is continuously adjustable.With the speed measurement function, the actual spindle speed is displayed in real time on the Mach3 interface, and the measurement is accurate and stable.The board is crafted by engineers and the design level is clear at a glance.With 256 bytes of NVRAM space, you can save the coordinate values and processing line numbers of 6 axes. No need to change the next time you power on.All motion axle outputs are differential signals that can be connected to servo high speed signal input.Can be set from the axle, support double X, double Y, double Z. Soft limit bottom layer processing, system is safer. RS485 isolated bus, can expand the input and output or connect to the servo read position, connect the grating scale, etc. (requires custom development).Fully isolated, all inputs and outputs are isolated from the motion control core, and pulse isolation is isolated using high speed 10M optocouplers. Support single and double pulse mode.Easy to upgrade, this product upgrade hardware layer firmware is only connected to the brush through USB, fast, not afraid of brushing, firmware is open, you can try for 1 hour, more than 1 hour will stop.Voltage, single-ended, differential three output options, 100PPR pulse output.Drive output type, strong anti-interference ability, long-distance transmission.Specification:Handwheel Working Voltage:5VHandwheel Three Output:Voltage, Single-Ended, DifferentialHandwheel Pulse Output:100PPRPackage List:1 x Control Board1 x USB Cord1 x Fixing Bracket1 x Handwheel1 x Hook.
