Relay is an electronic component that enables a circuit to control a larger load with a smaller signal. Relay is typically used in circuits where a low power signal is used to control a high power load. The 8 pin relay is one of the most common types of relays used in industrial and automotive applications. This journal article will discuss the wiring diagram for an 8 pin relay base, its components, and how to wire it.
Components of an 8 Pin Relay Base
An 8 pin relay base consists of the following components:
- Socket
- Contacts
- Coil
- Switching mechanism
The socket is the most visible component of the 8 pin relay base. It is used to hold the relay in place and to provide electrical connections to the relay. The socket is typically made of plastic, and it has eight holes where the relay pins are inserted.
The contacts are the switches that are activated by the relay. The contacts can be normally open (NO) or normally closed (NC). When the relay is activated, the contacts change state from NO to NC or from NC to NO, depending on the type of contact configuration.
The coil is the component that generates the magnetic field that activates the switching mechanism. The coil is typically made of copper wire, and it is wound around a magnetic core. When a voltage is applied to the coil, it generates a magnetic field that attracts the switching mechanism.
The switching mechanism is the component that is activated by the magnetic field generated by the coil. It can be a mechanical switch or a solid-state switch. When the switching mechanism is activated, it either connects or disconnects the contacts.
Wiring an 8 Pin Relay Base
The wiring of an 8 pin relay base is relatively simple. However, it is important to follow the wiring diagram to ensure that the relay functions properly. The following is the wiring diagram for an 8 pin relay base:
| Pin | Name | Description | Color | Connection | Function |
| 1 | Coil+ | Positive terminal of the coil | Red | Connect to the positive terminal of the power source | Activates the relay coil |
| 2 | Coil- | Negative terminal of the coil | Black | Connect to the negative terminal of the power source | Completes the circuit for the relay coil |
| 3 | NO1 | Normally open contact 1 | Green | Connect to the load that needs to be controlled by the relay | Connects the load to the power source when the relay is activated |
| 4 | COM1 | Common contact 1 | Yellow | Connect to the power source | Provides power to the load that needs to be controlled by the relay |
| 5 | NC1 | Normally closed contact 1 | Brown | Not connected | Disconnects the load from the power source when the relay is activated |
| 6 | NO2 | Normally open contact 2 | Blue | Connect to the load that needs to be controlled by the relay | Connects the load to the power source when the relay is activated |
| 7 | COM2 | Common contact 2 | White | Connect to the power source | Provides power to the load that needs to be controlled by the relay |
| 8 | NC2 | Normally closed contact 2 | Orange | Not connected | Disconnects the load from the power source when the relay is activated |
The wiring diagram shows the pin number, name, description, color, connection, and function of each pin. Pins 1 and 2 are the coil pins, and they are used to provide power to the coil. Pins 3, 4, and 5 are the contacts for the first circuit, while pins 6, 7, and 8 are the contacts for the second circuit.
