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、地理位置和气候作用因素 主要指海拔高度、环境温度、湿度、电磁干扰等因素。考虑到控制系统的普遍适用性，并考虑到一年四季可靠运行的特殊性，安装的关键部位需要采用具有绝缘高、抗电性能强的全密封型金属罩密封或塑封型，金属罩密封的产品优于塑封产品的finder中间继电器产品。因为只有全密封继电器才具有优异的耐受恶劣环境……

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安全继电器也是一种普通的finder安全继电器，这种finder安全继电器和普通的finder安全继电器是有很多的相似之处，虽然这种finder安全继电器的使用性能还是可以的。但是，这种finder安全继电器在使用一段时间后，也难免会遇到一些故障。 其实，建议大家在finder安全继电器出现故……

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. 查看详情+

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功率继电器触点的动作过程可以分为触点闭合和触点断开两部分，即继电器的吸合和释放过程。它们以一定的频率循环切换，形成触点开关现象。在触点闭合和触点断开的过程中，会出现许多特殊的物理现象和化学现象，比如触点电阻、触点抖动和电弧等。 触点闭合时的动作原理 当继电器的动触点和静触点相互接……
