There are many kinds of relays, and different kinds of relays will have different functions, but the relevant operating principles of these relays are the same, so there is no need to worry about this basic problem when using them. Finder time relay is also a common relay, which is mainl……

1、地理位置和氣候作用因素 主要指海拔高度、環(huán)境溫度、濕度、電磁干擾等因素。考慮到控制系統(tǒng)的普遍適用性，并考慮到一年四季可靠運(yùn)行的特殊性，安裝的關(guān)鍵部位需要采用具有絕緣高、抗電性能強(qiáng)的全密封型金屬罩密封或塑封型，金屬罩密封的產(chǎn)品優(yōu)于塑封產(chǎn)品的finder中間繼電器產(chǎn)品。因?yàn)橹挥腥芊饫^電器才具有優(yōu)異的耐受惡劣環(huán)境……

With the development of the times, the rapid development of microelectronic technology, electronic computer technology, modern communication technology, optoelectronic technology and space technology has put forward new requirements for finder relay technology. The development of new pro……

Finder has made important production modifications to the marks on PCB 34 series relays. The relay is also widely used in industrial automation, usually as a PLC interface - sold as 38 and 39 Series modular interface relays. Reason for change: the welding process accuracy of the cover is……

In modern production, the application of power system has been very popular. Many enterprises apply it to the power system when the machine is running. In this system, the use of relay is essential, because the position of relay is very important. As a key control equipment, we should kn……

Among various finder relay products used to control automation, power supply, time, temperature, liquid level and lighting every day around the world, we have also found equipment for special equipment. Drug administration and general hospital

Finder intermediate relay is used in relay protection and automatic control system to increase the number and capacity of contacts and transmit intermediate signals in the control circuit. There are mainly two kinds of delay methods for finder intermediate relay, namely, power on delay a……

finder安全繼電器也是一種普通的finder安全繼電器，這種finder安全繼電器和普通的finder安全繼電器是有很多的相似之處，雖然這種finder安全繼電器的使用性能還是可以的。但是，這種finder安全繼電器在使用一段時(shí)間后，也難免會(huì)遇到一些故障。 其實(shí)，建議大家在finder安全繼電器出現(xiàn)故……

In today's industrial control, we have to mention a product, that is, time relay. Time relay is a very important component in electrical control system. In many control systems, time relay is needed to realize time delay control. Finder time relay is an automatic control appliance that u……

As one of our commonly used switching devices, relays belong to the category of controllable switches. Relays are widely used, especially in electrical control. Since there are more than one or two types of relays, they are sometimes confused. Next, let's look at the various relays. 查看詳情+

Finder power relay is a device that can make one or more electrical output circuits jump when the input (or excitation) meets certain specified conditions. It can be used as a directional element of zero sequence current protection in neutral point direct grounding system. It is widely u……

finder功率繼電器觸點(diǎn)的動(dòng)作過(guò)程可以分為觸點(diǎn)閉合和觸點(diǎn)斷開(kāi)兩部分，即繼電器的吸合和釋放過(guò)程。它們以一定的頻率循環(huán)切換，形成觸點(diǎn)開(kāi)關(guān)現(xiàn)象。在觸點(diǎn)閉合和觸點(diǎn)斷開(kāi)的過(guò)程中，會(huì)出現(xiàn)許多特殊的物理現(xiàn)象和化學(xué)現(xiàn)象，比如觸點(diǎn)電阻、觸點(diǎn)抖動(dòng)和電弧等。 觸點(diǎn)閉合時(shí)的動(dòng)作原理 當(dāng)繼電器的動(dòng)觸點(diǎn)和靜觸點(diǎn)相互接……
