开关是最常见的电子元件,功能就是电路的接通和断开。接通则电流可以通过,反之电流无法通过。在各种电子设备、家用电器中都可以见到开关。 PLC可以方便地实现逻辑控制取代传统的继电器。
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。
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。
