Description:It is used to run the signal processing ofthe host computer ( LPT port ), with MACH3 CNC system software, and theperipheral machine dynamic electrical. It is suitable for CNC engravingmachine, CNC lathe, CNC plasmacutting machine, laser engraving machine, CNCmilling machines, machining centers and other machine tools. With the hostcomputer and the MACH3 series software, it can be the most cost-effective CNCsystem.Features:A special high speed chip is used toprocess the input and output (I/O) signals. It is capable of making the machinework stably, with the features of correcting and enlarging the signals thatremoving the unnecessary disturb signals.The computer LPT port supplies the powerindividually, separating from the power supply of other parts. Therefore, thecomputer and machine tool isolate effectively. It makes the data more secure,with further insurance of security and stability.There are 5 input signals, communicatingwith the host computer, which are isolated by the optical coupling. Among theoptical coupling isolation, the P11 and P12 are high-speed, which can be usedfor connecting main shaft encoder, or the same demanding signal as hand wheelA, B. 12V-OUT and 5V-OUT power output interface can be used to pick somenecessary power, such as the hall sensor switch and the proximity switch. Thereare 5 input ports, set to limit, origin, knife, start, stop, spindle speedinput, MPG input and any other one of the 5 functions.There are 12 output signal, which isallowed to controlling output, supporting as many as 6axlslinkage. Some ofthe output port is reusable functionality. Meanwhile, one port only can be usedas one function.There are 3 replays, P2, P3 and P4,which can support MACH3 control software programming. The relay's on or off canbe controlled through the control of MACH3 software. Each relay has attractedindicating lamp, which is more intuitive and convenient. The 3 relays can beused 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 theelectromagnetic valve device power switch. P2 port is for the spindle, P3 portis for the cooling liquid, P4 port can be defined.The high speed optical coupling isolationis used to control the rotational speed of spindle. The output port is parallelport 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 0-10Vlevel to control the inverter which only has analog speed control in themarket. Thus it can control the rotational speed of the spindle. It is importantthat the PWM output and 0-10V output can only choose one in two. They cannot beused at the same time.Interface board can be connected withthe cathode or total output to the stepper drive, or servo drive (servo drivermust support the digital signal). The output is the 5V level.Wide input voltage power supply:15-32VDC. The function of preventing reverse connection protection. 2 groups ofoutput voltage: 5V and 12V voltage, 100MA output capacity.Specifications:Model: MACH3V2.1-LUSB: Type BSize: 11*7.5*2.4cm/4.3*2.95*0.9in5 input portsportfunctionP10emergencystopP11reservedP12reservedP133axls limitP15reserved11 output portsportfunctionP4X pulseP5X directionP6Y pulseP7Y directionP8Z pulseP9Z directionP164pulseP174directionP2relay portP3relayportP14chargepumpPackage Includes:1 x Breakout BoardNote:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering..
