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。 [全文]

电路，实现逻辑控制、顺序控制，既可用于单台设备的控制，也可用于多机群控。如水泵的启停、阀门的开关、制水系统顺控、干除灰系统等。

1．2 工业过程控制

在工业生产过程当中，存在一些如温度、压力、流量、液位和速度等连续变化的量(即模拟量)，PLC采用相应的A／D和D／A转换模块及各种各样的控制算法程序来处理模拟量，完成闭环控制。PID调节是一般闭环控制系统中用得较多的一种调节方法。过程控制在冶金、化工等场合有非常广泛的应用，运城电厂主要应用在中央空调、采暖加热系统

Relay is a control device commonly used in our lives, which is a switch in the popular sense, which is turned off or on 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.

Circuit to achieve logic control, sequence control, can be used for single equipment control, can also be used for multi-machine group control. Such as the start and stop of the pump, the switch of the valve, the sequential control of the water system, the dry ash removal system, etc.

1.2 Industrial process control

In the industrial production process, there are some continuous changes such as temperature, pressure, flow, liquid level and speed (that is, the analog amount), PLC uses the corresponding A/D and D/A conversion modules and a variety of control algorithms to deal with the analog amount, complete closed-loop control. PID regulation is a kind of regulation method used in general closed-loop control system. Process control is widely used in metallurgy, chemical industry, etc. Yuncheng Power Plant is mainly used in central air conditioning, heating and heating system
