Introduction
A 12 volt relay is an electrical switch that is activated by a small electrical signal. It is used to control various electrical devices, such as motors, lights, and other appliances. A 5 pole double relay is a type of relay that has two sets of five pins. It is used to control two separate circuits at the same time. In this article, we will discuss the wiring diagram for a 5 pole double relay and how to connect it to various electrical devices.
What is a 12 Volt Relay?
A 12 volt relay is an electromechanical switch that is activated by an electrical signal. The signal can come from a variety of sources, such as a switch, a sensor, or a control unit. When the signal is applied, the relay switches from its resting position to its active position. This allows current to flow through the relay and control various electrical devices.
How Does a Relay Work?
A relay consists of four main components: a coil, a set of contacts, a spring, and an armature. When a signal is applied to the coil, it generates a magnetic field that pulls the armature towards the contacts. This causes the contacts to close, allowing current to flow through the circuit. When the signal is removed, the spring returns the armature to its resting position, opening the contacts and stopping the flow of current.
Types of Relays
There are several types of relays, including:
- Electromechanical relays
- Solid-state relays
- Magnetic latching relays
- Mercury-wetted relays
What is a 5 Pole Double Relay?
A 5 pole double relay is a type of relay that has two sets of five pins. It is used to control two separate circuits at the same time. The poles refer to the number of switches that the relay has, while the throws refer to the number of contacts that each switch can make. A double-pole relay has two switches, and a double-throw relay has two sets of contacts for each switch.
How to Identify a 5 Pole Double Relay
A 5 pole double relay can be identified by the number of pins on its base. It will have ten pins in total, with five on each side. The pins are numbered, with odd numbers on one side and even numbers on the other side. Each pin will be labeled with a letter, such as B, C, and NO (Normally Open).
Wiring Diagram for 5 Pole Double Relay
The wiring diagram for a 5 pole double relay is as follows:
| PIN NO. | DESCRIPTION | CONNECTED TO |
|---|---|---|
| 30 | Battery (12V) | Battery or power source |
| 87 | Output 1 (Normally Open) | Device or circuit 1 |
| 85 | Ground (or Negative) | Ground or negative side of the circuit |
| 86 | Switching Circuit | Switch or control unit |
| 87a | Output 2 (Normally Closed) | Device or circuit 2 |
Explanation of Pins
- PIN 30: This pin is connected to the battery or power source.
- PIN 87: This pin is the output for device or circuit 1. It is normally open and only closes when the relay is activated.
- PIN 85: This pin is connected to the ground or negative side of the circuit.
- PIN 86: This pin is connected to the switching circuit, such as a switch or control unit. When the switching circuit is activated, it sends a signal to this pin, causing the relay to activate.
- PIN 87a: This pin is the output for device or circuit 2. It is normally closed and only opens when the relay is activated.
Applications of 5 Pole Double Relay
A 5 pole double relay can be used for various applications, such as:
- Controlling two separate circuits
- Switching between two different modes of operation
- Preventing two circuits from interfering with each other
- Isolating two circuits from each other
FAQ
1. What is the purpose of a relay?
The purpose of a relay is to control various electrical devices, such as motors, lights, and appliances. It is used to switch high voltage or high current circuits using a low voltage or low current signal.
2. What is a double-pole relay?
A double-pole relay is a type of relay that has two switches. It can control two separate circuits at the same time.
3. How do you wire a 5 pole double relay?
You can wire a 5 pole double relay by following the wiring diagram provided by the manufacturer. You will need to connect the relay to the power source, switching circuit, and two separate devices or circuits.
4. What is the difference between a single-pole and a double-pole relay?
A single-pole relay has only one switch, while a double-pole relay has two switches. A double-pole relay can control two separate circuits at the same time, while a single-pole relay can only control one circuit.
5. What is a normally open contact?
A normally open contact is a type of contact that is open when the relay is at rest. It only closes when the relay is activated by a signal.
Conclusion
A 5 pole double relay is a useful tool for controlling two separate circuits at the same time. By understanding how it works and how to wire it, you can use it in a variety of applications. The wiring diagram and information provided in this article should give you a better understanding of how to use a 5 pole double relay in your projects.
