Introduction

Relays, otherwise called switches, close and opened the circuits electronically and electromechanically. They have wide applications and are used in control panels, manufacturing, and building automation. In electronic devices, relays detect overcurrent, overload, undercurrent, and reverse current and eventually ensure the protection of the electronic equipment. Let's understand its function and components more through the relay circuit diagram.

1. Understanding Relay Circuit Diagram

The relay circuit diagram focuses on the internal section of the relay. It consists of an iron core delimited with the control coin.

Power sources connect with the electromagnet through load contacts and a control switch in the circuit. When the energy is supplied to the circuit, magnetic fields intensify energizing.
Once the current in the coil goes off, a movable armature is forced back to the initial position, which is equal to half of the magnetic force and electric strength.
When power is applied to the coil due to the switching action of the transistor, maximum current flows as a result of the DC resistance of the coil.
They control larger voltages and amperes by having an amplifying effect. A small voltage applied to a relay coil can result in a large voltage being switched by the contacts.

3. Important Tips to Consider While Creating Relay Circuit Diagram

Now, as you have understood the different functions of every component in the relay circuit diagram, let's look into the tips to be followed while creating the circuit diagram.

Connect the input-output nodes accurately in the circuit diagram.
Use different colors to differentiate earth and other connections in the circuit diagram.
Mark the name of the components and their specifications to avoid confusion in the design.
Mark the positive and negative connection of the battery accurately.
Check if the wires are connected. In other cases, show they have a cross-connection.

Conclusion

The relay circuit diagram is simple, and its function can be easily understood. Make sure to connect all major components and keep the diagram simple. You may do it as a DIY project and learn more about its works. It is recommended to use EdrawMax Online to create similar-looking circuit diagrams for your projects.
