If you work in the automation industry, then you must be familiar with programmable logic controllers (PLCs). PLCs are digital computers that are used to automate industrial processes. Allen Bradley is a leading manufacturer of industrial automation equipment, including PLCs. In this article, we will discuss Allen Bradley PLC wiring diagrams in detail.
What is a Wiring Diagram?
A wiring diagram is a graphical representation of an electrical circuit. It shows the connection between various components of the circuit and the flow of electrical current. Wiring diagrams are used by engineers and electricians to design and troubleshoot electrical circuits.
Components of a Wiring Diagram
A typical wiring diagram consists of the following components:
- Power supply
- Control devices
- Input/output devices
- Wires and cables
The power supply provides electrical energy to the circuit. Control devices, such as timers and relays, control the operation of the circuit. Input/output devices, such as sensors and actuators, provide input to the circuit and receive output from the circuit. Wires and cables connect the components of the circuit.
Allen Bradley PLC Wiring Diagrams
Allen Bradley PLC wiring diagrams are used to show the connection between various components of Allen Bradley PLCs. The wiring diagrams are usually included in the PLC manuals and can also be found online.
Types of Wiring Diagrams
There are two types of Allen Bradley PLC wiring diagrams:
- Input/Output Wiring Diagrams
- Power Wiring Diagrams
The input/output wiring diagrams show the connection between the input/output devices and the PLC. The power wiring diagrams show the connection between the power supply and the PLC.
Reading an Allen Bradley PLC Wiring Diagram
Reading an Allen Bradley PLC wiring diagram can be intimidating for beginners. However, with a little practice, you can easily understand the connection between the various components of the circuit.
Let’s take a closer look at an Allen Bradley PLC wiring diagram:
| Component | Description |
|---|---|
| Power Supply | A power supply provides electrical energy to the circuit. |
| Input Devices | Input devices, such as sensors, provide input to the PLC. |
| Output Devices | Output devices, such as actuators, receive output from the PLC. |
| Control Devices | Control devices, such as timers and relays, control the operation of the circuit. |
| Wires and Cables | Wires and cables connect the components of the circuit. |
The wiring diagram shows the connection between the power supply, input devices, output devices, control devices, and wires and cables. Each component is labeled using a unique symbol or letter. The connection between the components is shown using lines.
