As a kind of electromagnetic switch, the contact (normally open and normally closed) of the intermediate relay and the rated voltage of the working coil of the intermediate relay should be paid attention to.

中間繼電器的使用注意事項

Precautions for use of intermediate relay

一、中間繼電器

1、 Intermediate relay

中間繼電器是一種電磁動作開關。

The intermediate relay is an electromagnetic switch.

中間繼電器由膠木外殼、銜鐵和線圈以及動靜觸點組成。

The intermediate relay is composed of bakelite shell, armature, coil and dynamic and static contacts.

當線圈接通電源時，銜鐵動作，帶動觸點閉合或斷開電路，從而達到多組開關同時動作的目的。

When the coil is connected to the power supply, the armature acts to drive the contact to close or open the circuit, so as to achieve the purpose of simultaneous action of multiple groups of switches.

一般中間繼電器在電路中起著小功率信號變換作用，也可控制大容嗽的觸頭動作，并能擴大受控電器的觸頭數量。

In general, the intermediate relay plays the role of small power signal conversion in the circuit, can also control the contact action of large capacity, and can expand the number of controlled electrical contacts.

二、中間繼電器的使用注意事項

2、 Precautions for use of intermediate relay

使用中間繼電器時，要注意二個問題：

When using the intermediate relay, we should pay attention to two problems

1、中間繼電器的觸頭較多，一鮮有8對、6對等，并分常開觸點和常閉觸點。

1. There are many contacts in the intermediate relay, including 8 pairs of contacts and 6 pairs of contacts.

但觸頭的容量較小，沒有主、輔觸頭之分，也沒有滅弧裝置，因此在應用中間繼電器控制電動機啟停時，只能用額定電流小于5A的小型電動機，并選用一種大型號的JZ7型中間繼電器控制。

But the capacity of the contact is small, there is no main contact and auxiliary contact, and there is no arc extinguishing device. Therefore, when using the intermediate relay to control the start and stop of the motor, only the small motor with the rated current less than 5A can be used, and a large JZ7 type intermediate relay can be used.

2、中間繼電器的工作線圈的額定電壓有多種，在應用中一定要使接人中間繼電器線圈的工作電壓符合中間繼電器線圈的額定電壓的要求。

2. There are many kinds of rated voltage of the working coil of the intermediate relay. In the application, the working voltage of the connecting intermediate relay coil must meet the requirements of the rated voltage of the intermediate relay coil.
