ABB UFC760BE42 3BHE004573R1042 接口板

ABB UFC760BE42接口板，传输作用：设置数据的寄存、缓冲逻辑，以适应CPU与外设之间的速度差异，接口通常由一些寄存器或RAM芯片组成，如果芯片足够大还可以实现批量数据的传输。

协调作用：能够协调CPU和外设两者在信息的类型和电平的差异，如电平转换驱动器、数／模或模／数转换器等。接口电路板是负责输入输出（I/O）的功能板，接口板由I/O专用器件、控制软件、接插件等组成，接口电路把主机（板）上的信号转换成外设可以识别的信号，有的还有功率输出功能。

如计算机的USB、1394、VGA、DVI-D、HDMI接口是数字信号接口，VGA、A/D、D/A、声卡是模拟、数字转换接口。接口电路板简单的只有机械的接插件，复杂的本身就是一个单片机系统。

ABB UFC760BE42 interface board, transmission role: set the data storage, buffer logic, to adapt to the speed difference between the CPU and peripherals, the interface is usually composed of some registers or RAM chips, if the chip is large enough to achieve batch data transmission.

Coordination function: The ability to coordinate the type and level differences between the CPU and peripherals, such as level conversion drivers, digital/analog or analog/digital converters. The interface circuit board is responsible for input and output (I/O) function board, the interface board is composed of I/O special devices, control software, connectors, etc., the interface circuit converts the signal on the host (board) into a signal that can be recognized by the peripheral, and some power output function.

For example, the computer's USB, 1394, VGA, DVI-D, HDMI interface is A digital signal interface, VGA, A/D, D/A, sound card is an analog, digital conversion interface. The interface circuit board is simple only mechanical connectors, and the complex itself is a single-chip microcomputer system.
