Relay Communication

The relay communication is a method of transmitting information from one point to another using an intermediary device called a relay.

A relay acts as a switch that can be controlled by a small electrical signal. When the signal is applied, the relay closes its contacts, allowing a larger current to flow through it. This larger current can then be used to operate a variety of devices, such as motors, lights, or other electronic circuits.

• Relays are commonly used in applications where a small signal needs to control a large power load.
• They are also used to isolate electrical circuits from each other, preventing damage from voltage surges or short circuits.
• Relays can be found in a wide range of devices, including automobiles, industrial equipment, and home appliances.
