Understanding the Relationship Between Allen Bradley and Rockwell
Allen-Bradley vs. Rockwell Automation: What’s the Difference?
In the world of industrial automation, few names carry as much recognition as Allen-Bradley and Rockwell Automation. Engineers, plant managers, OEMs, and maintenance teams encounter these brands daily—but many still ask the same question:
Are Allen-Bradley and Rockwell Automation the same company?
The short answer is yes — Allen-Bradley is a brand owned by Rockwell Automation. But the full story explains why both names continue to dominate the industrial automation industry today.
From PLCs and HMIs to VFDs and servo systems, Allen-Bradley products remain a standard across manufacturing facilities worldwide. Understanding the relationship between these two companies can help businesses make smarter automation decisions—and identify compatible alternatives when Rockwell products are unavailable or cost-prohibitive.
Allen-Bradley: From Small Startup to Industrial Automation Leader
The Early Years (1903–1910)
Allen-Bradley was founded in 1903 in Milwaukee, Wisconsin, originally under the name Compression Rheostat Company. The business focused on manufacturing resistors and motor control equipment for early electrical systems.
In 1910, the company was renamed Allen-Bradley, combining the names of founders Lynde Bradley and Stanton Allen.
What began as a small electrical components manufacturer would eventually become one of the most influential names in industrial automation history.
Allen-Bradley’s Rise in Industrial Automation
Throughout the 20th century, Allen-Bradley expanded aggressively into factory automation and industrial controls, becoming a global leader in:
✅ Programmable Logic Controllers (PLCs)
✅ Motor control systems
✅ Variable Frequency Drives (VFDs)
✅ Industrial relays and contactors
✅ Human Machine Interfaces (HMIs)
✅ Servo drives and motion control systems
By the 1980s, Allen-Bradley had established itself as one of the most trusted automation brands in manufacturing plants worldwide.
Why Allen-Bradley Became So Popular
Reliability
Allen-Bradley products earned a reputation for durability, long operational life, and dependable performance in demanding industrial environments.
Innovation
The company helped shape the PLC market and became a pioneer in modern industrial automation architecture.
Strong Industry Support
Manufacturers trusted Allen-Bradley because of its extensive support network, documentation, software ecosystem, and integration capabilities.
The Rockwell Acquisition: A Turning Point
In 1985, Rockwell International acquired Allen-Bradley for approximately $1.6 billion—one of the largest industrial automation acquisitions at the time.
The acquisition dramatically strengthened Rockwell’s position in the rapidly growing automation industry.
Why Did Rockwell Buy Allen-Bradley?
Rockwell recognized that industrial automation would become essential to modern manufacturing. Allen-Bradley already had:
- A dominant PLC platform
- Strong customer loyalty
- Advanced automation technology
- A massive installed base across North America
The acquisition allowed Rockwell to expand globally while building a complete industrial automation ecosystem around the Allen-Bradley product line.
So… Are Allen-Bradley and Rockwell Automation the Same Company?
Yes — Allen-Bradley Is a Rockwell Automation Brand
Today, Allen-Bradley is no longer an independent company. It operates as Rockwell Automation’s flagship hardware brand.
Rockwell Automation develops and supports:
- Allen-Bradley hardware
- FactoryTalk software
- Integrated architecture systems
- Industrial networking and motion control solutions
Even though the corporate structure changed, the Allen-Bradley name remains highly recognizable because it continues to appear on many of Rockwell’s most popular products.
