A relay is a type of switch that is used to control the electrical circuit of a device. It is essentially an electromagnetic switch that uses an electromagnet to open or close a set of contacts. Relays are commonly used in various electronic devices and automotive systems to control the flow of current. In this article, we will discuss the 13 pin relay wiring diagram and its components in detail.
What is a 13 Pin Relay?
A 13 pin relay is a type of relay that has 13 pins for connecting to the operating circuit. It is commonly used in automotive systems, such as cars and trucks, for controlling various electrical components. The 13 pin relay is also known as ISO 1724 or DIN 72585.
13 Pin Relay Wiring Diagram
The 13 pin relay wiring diagram consists of 13 pins that are numbered from 1 to 13. Each pin is connected to a different component of the relay, such as the coil, contacts, and diodes. The following table shows the pin layout and their corresponding functions:
| Pin No. | Function |
|---|---|
| 1 | Ground |
| 2 | Contact NO1 |
| 3 | Contact NO2 |
| 4 | Contact NO3 |
| 5 | Contact NO4 |
| 6 | Contact NO5 |
| 7 | Contact NO6 |
| 8 | Diode 1 |
| 9 | Power Supply |
| 10 | Diode 2 |
| 11 | Contact NC1 |
| 12 | Contact NC2 |
| 13 | Contact NC3 |

Components of a 13 Pin Relay
Coil
The coil is the main component of a relay that generates an electromagnetic field when a voltage is applied to it. The coil is connected to pins 1 and 9 of the 13 pin relay. When the coil is energized, it pulls the contacts towards it and closes the circuit. When the coil is de-energized, the contacts return to their normal position and the circuit is opened.
Contacts
The contacts are the switching elements of a relay and are used to make or break the circuit. The contacts are connected to pins 2 to 7 and 11 to 13 of the 13 pin relay. There are two types of contacts: normally open (NO) and normally closed (NC). When the coil is energized, the NO contacts close and the NC contacts open. When the coil is de-energized, the NO contacts open and the NC contacts close.
Diodes
The diodes are used to protect the circuit from voltage spikes that are generated when the relay is de-energized. The diodes are connected to pins 8 and 10 of the 13 pin relay. The diodes allow the current to flow in one direction only and prevent the backward flow of current.
