開關是最常見的電子元件，功能就是電路的接通和斷開。接通則電流可以通過，反之電流無法通過。在各種電子設備、家用電器中都可以見到開關。 PLC可以方便地實現邏輯控制取代傳統的繼電器。
繼電器是我們生活中常用的一種控制設備，通俗的意義上來說就是開關，在條件滿足的情況下關閉或者開啟。繼電器的開關特性在很多的控制系統尤其是離散的控制系統中得到廣泛的應用。從另一個角度來說，由于為某一個用途設計使用的電子電路，最終或多或少都需要和某一些機械設備相交互，所以繼電器也起到電子設備和機械設備的接口作用。
電路，實現邏輯控制、順序控制，既可用于單臺設備的控制，也可用于多機群控。如水泵的啟停、閥門的開關、制水系統順控、干除灰系統等。
