Desigo Building Automation Controllers
New labor-saving controllers with superior flexibility and intuitive engineering
Designed to integrate with a full range of open building automation platforms, including Desigo Optic's FIN Framework, the Desigo PXC family of controllers deliver increased data processing power and memory to quickly transform buildings into IoT-enabled high-performing buildings. The Desigo PXC controller family, including the PXC4, PXC5, and PXC7 offer flexible control and intuitive engineering with the single, easy-to-use ABT Site commissioning tool which enables faster engineering and commissioning to operate building automation systems more efficiently. With pre-configured application libraries, you can engineer and commission Desigo Automation PXCs faster, with less coding, to transform buildings in days, not weeks. Discover the power of Desigo PXCs to unlock inefficiencies, improve decision-making and sharpen building operations.

Tackle challenges and transform buildings in days, not weeks
The new Desigo PXC controllers allow you to easily tackle building automation challenges and transform facilities into IoT-enabed high-performing buildings. These buildings need to intelligently connect field devices, enable quick and easy engineering, be flexible and expandable to meet your building’s needs, and be open and cyber secure at the same time to provide all the information necessary to optimally manage a building. Discover how you can get started with Desigo building automation.
The PXC4 saves us approximately 200 million BTUs per year, or about 20% in annual cost savings – on top of what was already a very efficient system.Carey Shanks | Co-Founder Marble Distilling Co.
