Wiring a 5 pin relay is essential for many electrical projects. To successfully wire a 5 pin relay, you need to understand the purpose and function of each pin. Pin configuration plays a crucial role in determining how the relay will operate. Understanding this process can make your wiring tasks easier and more efficient. Let’s dive into the detailed steps on how to wire a 5 pin relay for your next project.
How to Wire a 5 Pin Relay: A Beginner’s Guide
Introduction to 5 Pin Relays
Have you ever wondered how to control high-power devices using a simple switch? That’s where a 5 pin relay comes into play! A 5 pin relay is a versatile electrical component that can be used in various applications, from automotive to home automation. In this beginner-friendly guide, we will walk you through the basics of wiring a 5 pin relay step by step.
Understanding the Components
Before we dive into the wiring process, let’s understand the components of a 5 pin relay:
– **Coil**: The coil is the primary input of the relay, which generates an electromagnetic field when powered.
– **NO (Normally Open) Pin**: This pin is connected to the common pin when the relay is activated.
– **NC (Normally Closed) Pin**: This pin is in connection with the common pin when the relay is not powered.
– **Common Pin**: The common pin is the central terminal that connects to either the NO or NC pin based on the relay’s state.
– **Control Pin**: This pin is used to activate the relay by providing power to the coil.
Gathering the Necessary Supplies
Before wiring the relay, make sure you have the following supplies handy:
– 5 Pin Relay
– Wire Strippers
– Electrical Wires
– Power Source
– High-Power Device (e.g., lights, fans)
Wiring Process
Step 1: Identify the Pins
Start by identifying the pins on your 5 pin relay. Typically, the pins are labeled as NC, NO, Common, and Control. Refer to the relay’s datasheet for specific pin configurations.
Step 2: Connect the Control Pin
Take one end of the wire and connect it to the control pin of the relay. This wire will be connected to the power source or a switch to activate the relay.
Step 3: Connect the Common Pin
Connect another wire to the common pin of the relay. This wire will be connected to the device you want to control (e.g., lights, fan).
Step 4: Connect the NO Pin
If you want the device to turn on when the relay is activated, connect a wire from the NO pin to the device. If you want the device to turn off when the relay is activated, skip this step.
Step 5: Power the Relay
Connect the other end of the control pin wire to a power source. When power is supplied to the control pin, the relay will switch its state, connecting the common pin either to the NO or NC pin.
Testing the Connection
Once you have wired the relay, it’s essential to test the connection to ensure everything is working correctly. Activate the relay by providing power to the control pin and observe if the device connected to the common pin functions as expected.
Congratulations! You’ve successfully learned how to wire a 5 pin relay. By following these simple steps, you can now control high-power devices with ease using a relay. Remember to adhere to safety precautions when working with electrical components. Have fun experimenting with different applications of 5 pin relays in your projects!
Remember, practice makes perfect, so feel free to experiment with different setups and applications of 5 pin relays to expand your knowledge further.

Frequently Asked Questions
What tools are needed to wire a 5 pin relay?
To wire a 5 pin relay, you will need basic tools such as wire cutters, wire strippers, a soldering iron (optional), electrical tape, and a wiring diagram specific to your relay and application.
How do you determine the wiring orientation of a 5 pin relay?
To determine the wiring orientation of a 5 pin relay, look at the relay with the pins facing up and the plastic tab on top. Pin numbering typically starts from the bottom left, going up to the top left, then from the bottom right to the top right.
What is the purpose of each pin on a 5 pin relay?
Pin 30 is the common connection, pin 87 is the normally open contact, pin 87a is the normally closed contact, pin 85 is the coil power input, and pin 86 is the coil power ground on a 5 pin relay.
How do you wire a 5 pin relay for a specific application, such as controlling lights?
To wire a 5 pin relay for controlling lights, connect the positive terminal of the power source to pin 30, the positive terminal of the lights to pin 87, the negative terminal of the lights to ground, and the negative terminal of the power source to pin 86. Pin 85 is connected to a switch or control signal.
Final Thoughts
In conclusion, wiring a 5 pin relay is a straightforward process that can significantly enhance your electrical circuit’s efficiency and safety. Understanding the relay’s pin configuration and utilizing the appropriate tools will ensure a successful installation. Follow the wiring diagram carefully, connecting the power source, load, and control signal to the designated pins. Testing the relay after wiring it will verify its functionality. Incorporating a 5 pin relay correctly can provide reliable control over various appliances and equipment in your projects.
