What is the Purpose of a Relay?

In a nutshell, the purpose of a relay is to control an electrical circuit. Relays are components utilised for controlling power and switching smaller current values within control circuits. They are commonly used in control panels, manufacturing, and building automation.

What are the benefits of Relays?

The benefits of using a relay are that you can switch a high current circuit using a lower current circuit and you can activate more than one circuit from a single input.

What are the 5 main Types of Relays

1) General Purpose Relays

General-purpose relays are applied mainly in industrial and power automation systems as well as signalling and protection systems. General-purpose relays are quick and easy to install and are very secure.

2) Automotive Flashers

Automotive flasher is OEM replacements for most applications. Available in two types: thermal type or electromechanical type. Used as a flashing light, especially by the Automotive industry.

3) Automotive Relays

Relays used by the automotive industry therefore can be found in cars and are also frequently used by the boat building/marine industry . This type of relay has either normally closed or normally open contacts and can handle up to 30 or 40 amps.

4) Heavy Duty Relays

Heavy-duty relays offer long electrical life and low life cycle costs with rated voltage of 12V and 24V DC. Often used within demanding applications due to its ability to stop heavy loads. Commonly used in the automation industry and used in industrial controls, and commercial and domestic electrical appliances.

5) Communication Relays

Communication relays are designed to transmit data signals to another device/destination. Communication relays can be commonly used (but not limited to) the automotive industry, broadcast industry, weather, and medical equipment.

What is the difference between a switch and a relay?

A switch is an electrical component employed to control the flow of electricity either on or off in a circuit. On the other hand, a relay has the same function as a switch but provides control over the flow of electricity.

How do I choose a Relay?

Each relay will possess an AC and DC rating. It is essential to calculate the AC watts and DC watts required and strictly abide by these limits. Overloading the relay beyond these ratings must be avoided.
