As the base, it has no coil, and the base like the time relay also has no coil. It is just a few connecting pieces, just like the daily terminal strip.

中間繼電器底座

Intermediate relay base

中間繼電器底座中每個角內部是有連接片引到端子上，在端子上會標注出各個連接片腳的序號，把中間繼電器各個腳插入底座中，就可以根據序號來進行接線。

Inside each corner of the intermediate relay base, a connecting piece is led to the terminal, and the serial number of each connecting piece pin will be marked on the terminal. Insert each pin of the intermediate relay into the base, and wiring can be carried out according to the serial number.

就算沒有底座使用導線直接連接中間繼電器引出的各個腳也是可以使用的，這也就間接證明了底座中并沒有線圈存在，那么中間繼電器的線圈在哪呢？

Even if there is no base, it can be used to directly connect the pins led out by the intermediate relay with wires, which indirectly proves that there is no coil in the base. Where is the coil of the intermediate relay?

中間繼電器

Intermediate relay

介紹中間繼電器的線圈，就不得不介紹中間繼電器，中間繼電器交流接觸器的原理是相同的，都是屬于電磁繼電器，使用線圈上電產生磁力吸合銜鐵進行動作，從而對被控對象進行通斷控制。

To introduce the coil of the intermediate relay, we have to introduce the intermediate relay. The principle of the AC contactor of the intermediate relay is the same. They all belong to the electromagnetic relay. The magnetic force generated by energizing the coil is used to pull in the armature for action, so as to control the on-off of the controlled object.

所以中間繼電器確實有線圈存在，它的線圈我們肉眼是可以看得到的，因為中間繼電器大部分設計的都是透明，非常便于觀察，如果在商店以后沒有聽到中間繼電器有吸合的聲音，也沒有觀察到觸點動作，很可能中間繼電器線圈失效。

Therefore, the intermediate relay does have a coil, and its coil can be seen by our naked eyes, because most of the intermediate relays are designed to be transparent and very easy to observe. If the intermediate relay does not hear the sound of pulling in and the contact action is not observed in the store, it is likely that the intermediate relay coil will fail.

但使用中間繼電器底座的時候一定要注意適配不同的中間繼電器引腳的含義也許不一樣，如果不是適配的底座很有可能出現接線錯誤。

However, when using the intermediate relay base, it must be noted that the meaning of adapting different intermediate relay pins may be different. If the base is not adapted, there is likely to be wiring error.
