What's up everybody! Today we're talking about relay wiring basics! Now, I know some of y'all might be scratching your heads and wondering "what the heck is a relay?". Don't worry, I got you covered.
What is a Relay?
A relay is basically an electrically operated switch. It allows a low voltage circuit to control a high voltage circuit. For example, you might use a relay to turn on your car's headlights. The low voltage circuit would be the switch in your car, and the high voltage circuit would be the actual headlights. The relay acts as a middleman, allowing the switch to control the headlights without the switch having to handle the high voltage directly.
How Does a Relay Work?
Relays have a few basic parts:
- Coil
- Contacts
- Spring
When you apply power to the coil, it creates a magnetic field which pulls the contacts towards it. When the contacts make contact, it completes the circuit and allows current to flow through it. When you remove power from the coil, the spring pulls the contacts back to their original position, breaking the circuit.
Why Use a Relay?
There are a few reasons why you might use a relay:
- Switching high voltages: as mentioned earlier, relays allow you to switch high voltages using a low voltage switch.
- Switching high currents: relays can handle high currents that might burn out a regular switch.
- Isolating circuits: relays can isolate one circuit from another, which can be useful in certain situations.
Now that you know a bit about relays, let's talk about wiring them up!
Wiring a Relay
Here's a diagram of a typical relay:
The numbers on the diagram correspond to the pins on the relay. Here's what they do:
- Pins 85 and 86: these pins are for the coil. You connect one pin to ground and the other to a switch (like a button or the ignition switch).
- Pins 30 and 87: these pins are for the contacts. You connect one pin to the voltage source (like the battery) and the other to the load (like the headlights).
That's pretty much it! Of course, there are more complex relay circuits out there, but this should give you a good starting point. Remember, always be careful when working with electricity!
