※ABB PFSK164 信号调节器 核算机与电话线信号转化设备

   调制解调器（(RModem)，是核算机与电话线之间进行信号转化的设备，由调制器和解调器两部分组成，调制器是把核算机的数字信号(如文件等)调制成可在电话钱上传输的声响信号的设备，在接纳端，解调器再把声响信号转化成核算机能接纳的数字信号。经过调制解调器和电话线就可以完成核算机之间的数据通信。

现在调制解调器主要有两种:内置式和外置式。

内置式调制解调镪其实就是一块核算机的扩展卡，刺进核算机内的一个扩展槽即可使用，它无需占用核算机的串行端口。它的连线适当简单，把电话线接头刺进卡上的“Line”插口，卡上另一个接口“Phone”则与电话机相连，平常不必调制解调器时，电话机使用—点也不受影响。

   外置式调制解调器则是一个放在核算机外部的盒式设备，它需占用电脑的一个审行端口，还需要衔接单独的电源才干作业，外置式调制解调器面板上有几盏状况指示灯，可方便您监督Modem的通讯状况，而且外置式调制解调器装置和拆卸简单，设置和修理也很方便，还便于带着。外置式调制解调器的衔接也很方便，phonei和line的接法同内置式调制解调器。但是外置式调制解调器得用一根串行电缆把核算机的一个串行口和调制解调器串行口连起来，这根串行线一般随外置式调制解调器配送。

调制解调器的一个重要性能参数是传输速率，现在市面上28.8、3356K和56的调制解调器都有，而且56K的调制解调器已经成为市场的主流产品。但由于国内通信线路的限制，以及用户太多世界出口太少的缘故，平常使用很难到达上述速率，因而，如果您使用时传输速率显现只要每秒几K甚至更低，您也不必怀疑电脑或调制解调器有什么问题.

Technical description: ABB PPC902CE101 power control board module

In the T industry no equipment through the palm called the power wave split board, the power grab board can often be divided into the power control board and high-frequency power control rice. The medium power supply control board is usually connected to the controlled medium power supply and other medium frequency industry is not ready for use, such as medium pre-furnace, medium frequency fire machine tool, medium frequency forging, etc., and the high pre-fabricated board used in the high pre-power supply can be divided into (GB5T and EKGFPS.GIT power supply high frequency board is widely used in high frequency machines due to its energy saving type. Common industrial equipment control plate is the control plate of tablet comfort mill, plastic molding machine control board, liquid filling machine control board, self-adhesive die cutting machine control board, automatic drilling machine control board, automatic tapping machine control board, positioning labeling machine control board, ultrasonic cleaning machine control board
