The Weidmüller Group has been a member of the EEBus Initiative e.V. since May 2026. The goal of this collaboration is to expand standardized communication in the smart grid and to further establish the EEBUS standard both in Germany and internationally.

Weidmüller entered the market for network-based control systems with the EEBUS Relay Converter (ERC), which was developed in collaboration with Power Plus Communications AG.

The converter translates digital EEBUS control commands into standardized relay circuits. This allows existing analog systems—such as heat pumps, photovoltaic systems, or charging stations—to be integrated into and controlled by smart grids. According to the companies, the solution supports compliance with the requirements of Section 14a of the Energy Industry Act (EnWG) and Section 9 of the Renewable Energy Sources Act (EEG).

Focus on International Distribution

EEBUS has been published as the international standard IEC 63380 since 2025. In Germany, the technology is recommended by the Federal Network Agency and the VDE FNN as the preferred interface for grid-friendly control.

In addition, the SPINE data model is part of the European standard EN 50631 and has been integrated into the SAREF4ENER ontology developed by the European Commission. The EEBus Initiative also collaborates with organizations and standardization initiatives in Europe and the United States.

According to Weidmüller, the EEBUS standard is also gaining increasing importance outside of Germany. The company intends to contribute its expertise in connection and automation technology to the further development and international adoption of the standard.

Dr. Robert Böhm, Managing Director of EEBus Initiative e.V., said: “EEBUS stands for an open, manufacturer-independent standard and has been internationally recognized as IEC 63380 since 2025. By making existing analog systems controllable as well, solutions such as the one Weidmüller has introduced to the market help integrate millions of existing systems into the standard.”
