Arbeitsweise Funktionsprinzip eines Relais („Arbeitsstromrelais“) Ein mechanisches Relais arbeitet meist nach dem Prinzip des Elektromagneten.Ein Strom in der Erregerspule erzeugt einen magnetischen Fluss durch den ferromagnetischen Kern und einen daran befindlichen, beweglich gelagerten, ebenfalls ferromagnetischen Anker.An einem Luftspalt kommt es zur Krafteinwirkung auf den Anker ...
11 de mar. de 2021 · Relays are widely used in various applications, such as switching, protection, and control of electrical systems. The center of a relay is an electromagnet which is a coil of wire. In older relays when electricity is applied to the electromagnet the coil becomes a magnet which electricity flows through. Newer relays tend to use newer electronic ...
继电器（英文名称：relay）是一种电控制器件，是当输入量（激励量）的变化达到规定要求时，在电气输出电路中使被控量发生预定的阶跃变化的一种电器。它具有控制系统（又称输入回路）和被控制系统（又称输出回路）之间的互动关系。通常应用于自动化的控制电路中，它实际上是用小电流去 ...
Safety Relays. Safety relays are a type of relay that is designed to interrupt the current when a certain level is reached. One advantage of using safety relays is that they are very efficient in terms of power consumption. Supervision relays. The relay supervisor is a relay that is designed to supervise the other relays in a circuit.
17 de oct. de 2019 · Relays are normally used in the control panels, manufacturing, and building automation to control the power along with switching the smaller current values in a control circuit. However, the supply of amplifying effect can help control the large amperes and voltages because if low voltage is applied to the relay coil, a large voltage can be switched by the contacts.
21 de oct. de 2021 · Relays work like some electrical products since they receive an electrical signal and send the signal to other equipment by turning the switch on and off. Even if the relay contact is normally closed or normally open, they are not energized. Its state will change only if you apply an electrical current to the contacts.
2 de dic. de 2021 · How relays work. Here are two simple animations illustrating how relays use one circuit to switch on a second circuit. When power flows through the first circuit (1), it activates the electromagnet (brown), generating a magnetic field (blue) that attracts a contact (red) and activates the second circuit (2).
