use of relay - EAS
Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal. Relays were first used in long-distance telegraph circuits as signal repeaters: they refresh the signal coming in from one circuit by transmitting it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations.en.wikipedia.org/wiki/Relay- Mọi người cũng hỏi
What Are Relays and Why Are They So Important For ...
https://amperite.com/blog/relaysRelays are electric switches that use electromagnetism to convert small electrical stimuli into larger currents. These conversions occur when electrical inputs activate electromagnets to either form or break existing circuits. By leveraging weak inputs to power stronger currents, relays ef…- Relays are highly versatile components that are just as effective in complex circuits as in simple ones. They can be used in the place of other forms of switches, or they can be specifically designed based on factors such as required amperage.

Relay - Wikipedia
https://en.wikipedia.org/wiki/RelayA relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof.

https://www3.panasonic.biz/ac/e/control/relay/app_circuits/index.jspRelays for PC board use have high sensitivity and high speed response characteristics, and because they respond sufficiently to chattering and bouncing, it is necessary to take care in their drive. When the frequency of use is low, with the delay in response time caused by a condenser, it is possible to absorb the chattering and bouncing.

What is the principle and function of the relay? - Quisure
https://www.quisure.com/blog/faq/what-is-the-principle-and-function-of-the-relay- A relay is an electronic control device, which has a control system (also called an input loop) and a controlled system (also called an output loop), and is usually used in automatic control circuits. It is actually an "automatic switch" that uses a smaller current to control a larger current. Relay plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
