About Allen-Bradley 

Allen-Bradley is recognized for excellence and innovation in the automation industrial and integrated control systems sector. It is now a Rockwell Automation flagship brand, one of the most recognized and reliable brands in the industry. 

Allen-Bradley was founded initially by Lynde Bradley in 1903 with the financial backing of investor Dr. Stanton Allen. The organization was eventually named the Allen-Bradley Company. Allen-Bradley began producing programmable logic controllers when inventor Odo Josef Struger came to work for them. Struger is often referred to as the father of the PLC, an acronym he helped introduce.

What Is a Programmable Logic Controller?

A programmable logic controller (PLC) is a miniature industrial computer (CPU) that contains the hardware and software for automating industrial electromechanical processes running the machinery in factory assembly lines, amusement rides, and food processing.

You can program multiple digital and analog inputs and outputs (I/O interface system) with…

• Extended temperature ranges
• Immunity to electrical noise
• Resistance to vibration and impact

PLCs Run a Four-Step Operational Process in a Repeating Loop

1. Input scan: looks for all connected input devices
2. Program scan: executes user-created program logic
3. Output scan: runs or shuts off all connected output devices
4. Housekeeping: communicates with programming devices and performs internal diagnostics

What Can You Attach to a PLC?

All types of sensors and output devices. For example:

• Proximity or photoelectric sensors
• Limit switches
• Pushbuttons

Choosing a Controller

Select the right controller for the job by determining ahead of time what you need your system to do and the specifics about the system itself.

Here are just a few of the questions to ask when deciding on a controller for your next system.

• Is it a new system or an existing one? How old is it?
• What is the environment like where the system will be installed? Is it hot, dusty, or full of vibration?
• How many discrete devices does your system have? Are the AC or DC components?
• How many analog devices are there?
• Will your system require any special features such as a real-time clock or high-end positioning?
• How much memory does the CPU need to run the system efficiently?
• Where will the I/O be located? Will it be local only or local and remote?
• Will the controller be communicating with other systems or networks? Will it need to communicate with field devices?
• Does your system require traditional programming instructions, or are special instructions needed?

Each of these questions examines a distinct set of requirements to guide you to the right controller for the job.
