常用小型继电器原理及底座接线图

 

常用小型继电器有直流式和交流式,

其外形一样,

小型继电器其触点一般为两组常开两组常闭或四

小型继电器组常开四组常闭,

小型继电器对应的插座也比较统一,

小型继电器但有时印刷的号码不是很清楚,

小型继电器为了使大家清晰

的掌握对应接线关系,防止错接,现将其电器原理图和实物接线图提供给大家参考。

 

 

注意事项:对于直流电源工作方式的继电器应将

14

号端子接正极,

13

号端子接负极,

这样发光二极管才能亮,

接反则不亮,

当然接反了也比影响动作效果。

对于交流电源工作方

式的继电器则没有极性之分,二极管一定亮。
