A wiring diagram for a 5 pin relay can be a complex and intimidating task. Without a thorough understanding of the diagram, it can be difficult to visualize and understand the wiring system and its components. In this article, we will discuss the basic components of a 5 pin relay, how to read a wiring diagram and how to properly connect the various components.
Components of a 5 Pin Relay
A 5 pin relay is comprised of five terminals. These five terminals are divided into two categories—the power terminals and the control terminals. The power terminals are labeled 85, 86, 87 and 30. The control terminals are labeled 87a, 87 and 85a. 85 corresponds to the power input, 86 is the normally open contact, 87 is the normally closed contact, 87a is the common terminal and 85a is the ground terminal.
Reading a Wiring Diagram for 5 Pin Relay
When reading a wiring diagram for a 5 pin relay, it is important to understand the symbols used to represent the components. For example, a circle with a line through it is used to represent a normally open contact and a circle with a dot in the middle is used to represent a normally closed contact. This is important to understand as it will help you visualize how the components are connected to each other.
Connecting the Components
Once you have properly identified the components and understood the wiring diagram, you are ready to start connecting the components. It is important to ensure that the terminals are correctly connected. This means that the power terminals 85, 86, 87 and 30 must be connected in the correct order and the control terminals 87a, 87 and 85a must be connected in the correct order as well.
Conclusion
Understanding a wiring diagram for a 5 pin relay can be daunting, but with a thorough understanding of the diagram, it becomes much easier. The components must be correctly identified and connected in the correct order for the system to work properly. With the help of this guide, you should be well on your way to properly connecting the components and understanding a wiring diagram for a 5 pin relay.
