Specification Brand : Hilitand BulletPoint1 : A special high speed chip is used to process the input and output (I/O) . It is capable of making the machine work stably, with the features of correcting and enlarging the that removing the unnecessary disturb . The computer LPT po BulletPoint2 : 5 input , communicating with the host computer, which are isolated by the optical coupling. Among the optical coupling isolation, the P11 and P12 are high-speed, which can be used for connecting main shaft encoder, or the same demanding BulletPoint3 : 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 within 2.5KHZ. On the interface board ,there is a D/A circuit, with PWM to a 0-10V. BulletPoint4 : 12 output , which is allowed to controlling output, supporting as many as 6 axls linkage. Some of the output port is reusable functionality. Meanwhile, one port only can be used as one function BulletPoint5 : 3 replays, P2, P3 and P4, which can support control software programming. The relay's on or off can be controlled through the control of software. Each relay has attracted indicating lamp, which is more intuitive and convenient.
