日本OMRON继电器，欧姆龙继电器

3、固态继电器（SSR）的工作原理和特性
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，以光电隔离型为最多。
OMRON继电器线圈在电路中用一个长方框符号表示，如果继电器有两个线圈，就画两个并列的长方框。同时在长方框内或长方框旁标上继电器的文字符号“J”。继电器的触点有两种表示方法：一种是把它们直接画在长方框一侧，这种表示法较为直观。另一种是按照电路连接的需要，把各个触点分别画到各自的控制电路中，通常在同一继电器的触点与线圈旁分别标注上相同的文字符号，并将触点组编上号码，以示区别。继电器的触点有三种基本形式：
1.动合型（H型）线圈不通电时两触点是断开的，通电后，两个触点就闭合。以合字的拼音字头“H”表示。
2.动断型（D型）线圈不通电时两触点是闭合的，通电后两个触点就断开。用断字的拼音字头“D”表示。
3.转换型（Z型）这是触点组型。这种触点组共有三个触点，即中间是动触点，上下各一个静触点。线圈不通电时，动触点和其中一个静触点断开和另一个闭合，线圈通电后，动触点就移动，使原来断开的成闭合，原来闭合的成断开状态，达到转换的目的。这样的触点组称为转换触点。用“转”字的拼音字头“z”表示。
