automation relay（自动化继电器）是一种在自动化控制系统中常用的电气设备，通常用于控制电路的开关操作。它通过电信号（通常是低电压信号）控制机械或电气开关的开闭，从而实现对设备或电路的控制。
常见类型： 电磁继电器（Electromagnetic Relay）：这是最传统的一种继电器，利用电磁感应原理工作。当继电器线圈通电时，产生的磁场会吸引铁芯，从而切换继电器的开关状态。 固态继电器（Solid State Relay，SSR）：与电磁继电器不同，固态继电器采用电子元件如晶体管或二极管来实现开关操作，没有机械部件，因此没有磨损，使用寿命更长。 时间继电器（Timer Relay）：这种继电器可以在一定时间后自动切换开关状态，广泛用于需要延时启动或停止的场合。 热继电器（Thermal Relay）：主要用于电动机保护，依据电流产生的热量来操作，防止过载损坏设备。 应用领域： 自动化控制系统：在工业自动化、生产线控制中，通过继电器实现对电动机、阀门、灯光、传感器等设备的控制。 保护系统：用于设备过载、短路保护，常见于电气配电系统中。 信号控制：在需要开关控制或信号转换的场合，继电器常被用于信号的传输与转换。 远程控制：通过远程开关继电器，实现设备远程控制。 主要功能： 开关控制：继电器能够对电气系统中的电流进行通断控制，具有远程控制能力。 隔离作用：继电器可以有效地将控制电路与负载电路进行电气隔离，确保设备安全。 自动化：继电器可以在自动化控制系统中，根据输入信号自动切换状态，实现智能化控制。 常见特点：
