Understanding Electrical Wiring Diagram Symbols Relay
Electrical wiring diagrams are essential for electricians and other professionals who install, maintain and troubleshoot electrical systems. Without a clear understanding of the symbols used in wiring diagrams, it can be difficult to correctly interpret a diagram and correctly install electrical components and wires. An understanding of the different symbols used in wiring diagrams will ensure that installation and repair is less time consuming and more accurate.
Relays are often included on wiring diagrams, as they control the flow of current from one component to another. The symbols used to represent relays on wiring diagrams can vary, depending on the type of relay being used. To understand the wiring diagrams accurately, it is important to know what each symbol stands for and how to interpret them.
How to Read Wiring Diagrams
When reading wiring diagrams, it is important to know what each symbol represents. Each component has its own symbol, and the symbol may vary slightly depending on the manufacturer. It is also important to note the key symbols used to designate the type of connection, such as a parallel connection, or a series connection. Once you understand the symbols used in the diagram, it is much easier to interpret the diagram and make the necessary connections.
Symbols for Electrical Wiring Diagrams
The most important symbols to understand when reading electrical wiring diagrams are the symbols for components, including switches, resistors, transistors and relays. Each component is represented by an icon that depicts its basic structure. For example, a switch symbol may have two vertical lines with a double circle in the center, while a resistor symbol may be a single vertical line with a zigzag pattern. Understanding these symbols is essential to interpret the wiring diagram correctly.
Symbols for Relays
Relays are electrical switches that can be used to control the flow of current. As with other symbols, the icons used to represent relays on wiring diagrams vary by manufacturer. Common symbols include two squares side-by-side, two circles side-by-side, or an oval-shaped symbol. Some diagrams may contain a table to explain the meanings of each symbol. The table may include the following information:
- A description of the symbol
- The type of relay
- The number of contacts on the relay
- The type of contact (normally open or normally closed)
By understanding the symbols used to represent relays on wiring diagrams, it will be easier to correctly interpret the diagrams and correctly install the electrical components. This will ensure that the installation and repair process is accurate and efficient.
