Klöckner Moeller, often simply referred to as Moeller, was a German company specializing in electrical engineering and industrial automation products. Before being acquired by Eaton Corporation in 2008, Moeller had established itself as a prominent player in the area of Programmable Logic Controllers (PLCs), among other automation and control equipment.

Moeller PLCs were known for their robustness and versatility. They were used in various industrial applications ranging from manufacturing and assembly lines to process control in sectors like chemicals, pharmaceuticals, and food and beverage. These PLCs were particularly popular in Europe but were used globally in various types of industrial automation projects.

The PLCs from Moeller often featured a modular design, allowing users to expand their control systems as needed. They were capable of handling both digital and analog inputs/outputs and supported a variety of communication protocols, making them compatible with a wide range of other industrial equipment.

The software for programming Moeller PLCs was designed to be user-friendly, offering graphical interfaces and ladder logic programming options. The company also offered training and support to help users get the most out of their PLC systems.

Since the acquisition by Eaton, the Moeller line of PLCs has been integrated into Eaton’s broader automation and control solutions portfolio. While the Moeller brand name has been phased out in favor of the Eaton brand, the technologies and features that made Moeller PLCs popular continue to be developed and offered under the Eaton umbrella.

Eaton has continued to innovate in the field of PLCs, building on Moeller’s solid foundation. They offer PLCs that are designed to meet modern industrial requirements, such as Internet of Things (IoT) connectivity, data analytics capabilities, and increased cyber-security measures.

Overall, the legacy of Klöckner Moeller in the field of PLCs is one of robust, versatile systems that were built to meet the diverse needs of industrial automation. That legacy continues under the Eaton brand, which aims to provide cutting-edge, integrated solutions for industrial control and automation.
