853-049542-173多年来可编程控制器(以下简称PLC)从其产生到现在，实现了接线逻辑到存储逻辑的飞跃；其功能从弱到强，实现了逻辑控制到数字控制的进步；其应用领域从小到大，实现了单体设备简单控制到胜任运动控制、过程控制及集散控制等各种任务的跨越。

今天的PLC在处理模拟量、数字运算、人机接口和网络的各方面能力都已大幅提高，成为工业控制领域的主流控制设备，在各行各业发挥着越来越大的作用。 

853-049542-173继电器是我们生活中常用的一种控制设备，通俗的意义上来说就是开关，在条件满足的情况下关闭或者开启。

继电器的开关特性在很多的控制系统尤其是离散的控制系统中得到广泛的应用。从另一个角度来说，由于为某一个用途设计使用的电子电路，最终或多或少都需要和某一些机械设备相交互，所以继电器也起到电子设备和机械设备的接口作用。

Over the years, the programmable controller (hereinafter referred to as PLC) has realized the leap from wiring logic to storage logic from its generation to the present; Its function from weak to strong, to achieve the progress of logic control to digital control; Its application field has grown from small to large, realizing simple control of single equipment to competent motion control, process control and distributed control and other tasks.

Today's PLC in the processing of analog, digital computing, man-machine interface and network capabilities have been greatly improved, become the mainstream control equipment in the field of industrial control, in all walks of life is playing an increasing role.

853-049542-173 relay is a control device commonly used in our lives, which is a switch in the popular sense, closed or opened when the conditions are met.

The switching characteristics of relays are widely used in many control systems, especially in discrete control systems. From another point of view, because the electronic circuit designed for a certain purpose needs to interact with some mechanical equipment more or less in the end, the relay also plays an interface role between electronic equipment and mechanical equipment.
