Allen-Bradley 700 relay is widely used in various industrial applications to control electrical circuits. As such, understanding its wiring diagram is critical for electricians and technicians who work in industries that rely on this type of relay. This guide will provide you with a complete overview of the Allen-Bradley 700 relay wiring diagram, including how to read it, frequently asked questions, and more.
What is Allen-Bradley 700 Relay?
The Allen-Bradley 700 relay is a general-purpose relay that is typically used in industrial control applications to control electrical circuits. It is ideal for use in applications that require high-speed switching or high reliability. It is a versatile relay that can be used in a wide range of applications, including conveyor systems, pumps, and motor control circuits.
Understanding the Wiring Diagram
The Allen-Bradley 700 relay wiring diagram is a graphical representation of the connections between the different components of the relay. It is a vital tool for electricians and technicians who are involved in wiring the relay for use in industrial applications. The wiring diagram typically includes the following components:
| Component | Description |
|---|---|
| Coil | The coil is the main component that creates the magnetic field when energized. |
| Contacts | The contacts are the switches that open and close the electrical circuit when the relay is energized or de-energized. |
| Terminals | The terminals are the connection points of the relay to the external circuit. |
| Operating Voltage | The operating voltage is the voltage that is required to energize the coil and activate the contacts. |
The wiring diagram typically shows the connections between the coil, contacts, terminals, and operating voltage. It also shows the physical location of each component and the direction of current flow in the circuit.
Reading the Wiring Diagram
Reading the Allen-Bradley 700 relay wiring diagram requires an understanding of the symbols and notations used in the diagram. The following are some of the symbols that are commonly used in the wiring diagram:
| Symbol | Meaning |
|---|---|
| COIL | Represents the relay coil. |
| NO | Represents the normally open contact. |
| NC | Represents the normally closed contact. |
| L1, L2 | Represents the line voltage terminals. |
The wiring diagram may also include special notations that indicate specific wiring instructions or requirements. For example, a dashed line may indicate that the wires need to be twisted together or that a jumper wire is required to complete the circuit.
Frequently Asked Questions (FAQ)
How do I wire an Allen-Bradley 700 relay?
The wiring instructions for the Allen-Bradley 700 relay vary depending on the application. However, the wiring diagram typically provides a clear guide on how to wire the relay. It is essential to follow the manufacturer’s instructions and ensure that the wiring is done correctly to prevent electrical accidents or damage to equipment.
What is the operating voltage of the Allen-Bradley 700 relay?
The operating voltage of the Allen-Bradley 700 relay varies depending on the specific model or application. Typically, the operating voltage ranges from 12 to 240 volts AC or DC.
Can the Allen-Bradley 700 relay be used for motor control circuits?
Yes, the Allen-Bradley 700 relay is ideal for use in motor control circuits. It is designed to handle high current and voltage loads, making it suitable for use in industrial applications where control over motors is required.
What is the difference between a normally open and normally closed contact?
A normally open contact is an electrical switch that is open when the relay coil is not energized. When the coil is energized, the normally open contact closes, completing the electrical circuit. A normally closed contact, on the other hand, is an electrical switch that is closed when the relay coil is not energized. When the coil is energized, the normally closed contact opens, breaking the electrical circuit.
What precautions should I take when wiring the Allen-Bradley 700 relay?
When wiring the Allen-Bradley 700 relay, it is essential to follow the manufacturer’s instructions and wiring diagram. Ensure that the wiring connections are secure and that the correct wire size is used. It is also crucial to follow standard safety procedures such as wearing protective gear and turning off the power source before working on the electrical circuit.
In Conclusion
Understanding the Allen-Bradley 700 relay wiring diagram is critical for electricians and technicians who work in industrial applications. This guide has provided a comprehensive overview of the wiring diagram, including how to read it, frequently asked questions, and more. By following the manufacturer’s instructions and safety procedures, you can wire the Allen-Bradley 700 relay correctly and ensure smooth operation of your electrical circuits.
