Allen-Bradley, now known as Rockwell Automation, has a rich history that spans over a century. The company was founded in 1903 by Lynde Bradley and Dr. Stanton Allen in Milwaukee, Wisconsin, United States.

Initially, Allen-Bradley focused on manufacturing compression rheostats, a type of resistor used for controlling electrical current. The company quickly gained recognition for its high-quality products and innovative engineering solutions.

In the early 20th century, Allen-Bradley expanded its product offerings to include motor controllers, switches, and relays. These products played a critical role in the burgeoning industrial automation industry, supporting the growth of manufacturing processes.

One of the significant milestones in Allen-Bradley’s history came in the 1960s when the company introduced the Programmable Logic Controller (PLC). The PLC revolutionized industrial automation by providing a flexible and efficient means of controlling machinery and processes. Allen-Bradley’s PLCs quickly gained popularity and became a standard in the industry.

In 1985, Allen-Bradley was acquired by Rockwell International, and the company became a part of the Rockwell Automation division. This merger allowed for greater integration of automation solutions, expanding the company’s capabilities and market reach.

Throughout the following decades, Allen-Bradley, operating under the Rockwell Automation brand, continued to innovate and develop advanced automation technologies. The company introduced new generations of PLCs, Human-Machine Interfaces (HMIs), industrial control systems, and software solutions.
