what is a relay and how does it work? before discussing more about how does relay work then you should know first what is a relay

what ia a relay? Relay is an electronic component that helps to disconnect or connect the electrical flow indirectly. The relay is also called a magnetic shift

The way the relay works is when the electric flow is connected, then there will be contact between the plate so that the electric current can flow. In other words the relay function is as a switch indirectly

The relay symbols in the electronics circuit are as follows

with a little description above you already know what is a relay. after you know about what is a relay then the next you also need to know about how does relay work

how does relay work?

On the relay there is an iron-core coil that when the coil is electrified then the coil will turn a magnet and pull the plate so that there is contact

When the contact is connected, then the flow of electricity along the load will flow. The payload on the relay can be a lamp, water pump and other electrical equipment

Relay function in electrical circuit

The relay function on the electrical circuit among others is

  • connect and disconnect the electricity indirectly
  • connect and disconnect the power line simultaneously

Here’s some more details

connect and disconnect the electricity indirectly

Relays can be used to join and disconnect electric current without being connected to a controlled circuit

The circuit can we take on the electrical controller as in the automatic lights

Here’s a sample circuit

how does relay work

connect and disconnect the power line simultaneously

Relays can also be used to join and disconnect power simultaneously, which means that we can control many electrical appliances with just a switch

Cases of such sequences are as follows

the definition and function of relay

In the above circuit using only a switch we can turn on and off electrical equipment but with a main switch

Apiece of the electrical circuits in the image above are separated from each other

Input 1 is connected to a power source in equipment 1 whereas output 1 is connected to the load to be connected as well as input 2 and output 2 and so on

In the circuit of electronics near the relay is usually mounted diode as a series of snubber circuit that serves to release the flow of electricity when there is a power outage on the relay coil

so am article about what is a relay and how does relay work. Also read about the definition of multiplexer and demultiplexer
