功率方向继电器

当输入量（如电压、电流、温度等）达到规定值时，使被控制的输出电路导通或断开的电器。可分为电气量（如电流、电压、频率、功率等）继电器及非电气量（如温度、压力、速度等）继电器两大类。具有动作快、工作稳定、使用寿命长、体积小等优点。广泛应用于电力保护、自动化、运动、遥控、测量和通信等装置中。[1]

电磁继电器

电磁继电器一般由铁芯、线圈、衔铁、触点簧片等组成的。只要在线圈两端加上一定的电压，线圈中就会流过一定的电流，从而产生电磁效应，衔铁就会在电磁力吸引的作用下克服返回弹簧的拉力吸向铁芯，从而带动衔铁的动触点与静触点（常开触点）吸合。当线圈断电后，电磁的吸力也随之消失，衔铁就会在弹簧的反作用力返回原来的位置，使动触点与原来的静触点（常闭触点）释放。这样吸合、释放，从而达到了在电路中的导通、切断的目的。对于继电器的“常开、常闭”触点，可以这样来区分：继电器线圈未通电时处于断开状态的静触点，称为“常开触点”；处于接通状态的静触点称为“常闭触点”。继电器一般有两股电路，为低压控制电路和高压工作电路。

固态继电器（SSR）

固态继电器是一种两个接线端为输入端，另两个接线端为输出端的四端器件，中间采用隔离器件实现输入输出的电隔离。

固态继电器按负载电源类型可分为交流型和直流型。按开关型式可分为常开型和常闭型。按隔离型式可分为混合型、变压器隔离型和光电隔离型，以光电隔离型为较多。
