Process Interface - More than 20 Years of PSI-Gateway Technology

The development of the first generation of PSI gateway was completed in 1998. The rapid technological progress of electronic components and the resulting price benefits allow PSI ongoing enhancements of the functionally compatible telecontrol gateways.

With the components of this modular product family, powerful and economical interfaces can be configured for standard tasks. The process coupling supports information via serial connections and digital networks. The flexibility of our technology also enables the implementation of project-specific custom solutions.

The telecontrol gateway components are fully integrated in the information management of the overall system. The communication with systems installed in multiple locations is based on the current security standards.
