Features:
A dedicated high-speed chip is used to process input and output (I/O) signals. It can make the machine work stably, has the function of correcting and amplifying the signal, and removes unnecessary interference signals. The computer LPT port is powered separately and is separated from other parts of the power supply. Therefore, the computer is effectively isolated from the machine tool. Makes data more secure, further ensuring security and stability. There are 5 input signals, which communicate with the host computer and are isolated by optocouplers. In optocoupler isolation, P11 and P12 are high-speed, which can be used to connect the spindle encoder, or the same demanding signals as handwheels A and B. Some necessary power supplies, such as Hall sensor switches and proximity switches, can be selected using the 12V-OUT and 5V-OUT power output connectors. There are 5 input ports, set any one of 5 functions such as limit, origin, tool, start, stop, spindle speed input, MPG input. There are 12 output signals, allowing control output, supporting up to 6 axis linkage. Some output ports are reusable functions. At the same time, a port can only be used as one function. There are 3 playbacks, P2, P3 and P4, which can support MACH3 control software programming. The on-off of the relay can be controlled by the control of MACH3 software. Each relay has an attraction indicator, which is more intuitive and convenient. 3 relays can be used to control liquid coolant, mist coolant, liquid coolant, etc. on and off. They can also be used to control the power switch of solenoid valve units. P2 is the spindle, P3 is the coolant, and P4 can be defined. High-speed optocoupler isolation controls the spindle speed. The output port is parallel port P1, which can output PWM signals within 2.5KHz. There is a D/A circuit on the interface board, PWM to 0-10V. This circuit can output 0-10V level to control inverters that only have analog speed regulation on the market. Thus, the speed of the spindle can be controlled. The important thing is that PWM output and 0-10V output can only be selected. They cannot be used simultaneously. The interface board can be connected to the cathode or the total output to the stepper driver or servo driver (the servo driver must support digital signals). The output is 5V level. Wide input voltage power supply: 15-32VDC. Anti-reverse connection protection function. 2 sets of output voltage: 5V and 12V voltage, 100MA output capacity.
