Allen-Bradley (abbreviated as A-B) is a globally renowned manufacturer of industrial automation and control products. It is currently under the Rockwell Automation Group. The company was founded in 1903 by Lynde Bradley and Stanton Allen in Milwaukee, Wisconsin, USA. Initially, it focused on manufacturing motor controllers. After more than a century of development, Allen-Bradley has become a benchmark brand in the field of industrial automation, renowned worldwide for its high-quality PLCs (Programmable Logic Controllers), HMIs (Human-Machine Interfaces), frequency converters, servo systems, and industrial network solutions. 

Core Products and Technologies

Allen-Bradley's product line covers key areas of industrial automation, mainly including: 

Programmable Logic Controller (PLC): Such as ControlLogix, CompactLogix and MicroLogix series, are widely used in manufacturing, energy and transportation industries. 

Human-Machine Interface (HMI): The PanelView series of touch screens offer an intuitive operation experience. 

Frequency converters and servo drives: PowerFlex frequency converters and Kinetix servo systems are used for precise motion control. 

Industrial networks and communications: This includes industrial protocols such as EtherNet/IP, DeviceNet and ControlNet, which facilitate efficient interconnection of devices. 

Safety and sensing technologies: such as GuardPLC safety control system and Bulletin series sensors. 

Development History and Industry Impact

In 1985, Allen-Bradley was acquired by Rockwell International and later merged into Rockwell Automation, further consolidating its leadership position in the automation industry. The Logix control platform and FactoryTalk industrial software suite of Allen-Bradley became the core technologies of intelligent manufacturing, and were widely applied in industries such as automobiles, food and beverage, petrochemicals, and pharmaceuticals.
