Our company has been based in a bilingual (German and French) part of western Switzerland since it was established.
At home in Switzerland

The locality is home to such world famous companies as Swatch and Logitech, together with leading schools and universities in the technical field.

Like Switzerland itself, our company and our technology have been built on grassroots democracy. Both operate according to the “bottom up” principle. The needs of the grassroots are taken seriously and integrated into the development and manufacturing process. The quality management system, certified according to ISO 9001, can be viewed on internet by anyone and demonstrates with openness and transparency the rules by which we operate and the objectives we work towards.

Key corporate data:
  • 70 million Euro annual sales
  • 340 employees, 70 of them in the development
Production volume:
  • 2 million I/O points per year
  • 40 000 CPUs per year
  • 700 000 small devices per year

Development, production and sale of industrial-grade electronic components and systems for control/automation engineering.

Our mission since more than 50 years

In the early days, Saia Burgess Controls mainly manufactured electronic timers. The spectrum of use extended from house installations to machine technology.

At the end of the seventies Saia Burgess Controls became a pioneer in the field of programmable logic controllers (PLCs), known and used today under the Saia PCD® brand name. In parallel with this component business, Saia Burgess Controls grew to become a supplier of systems for instrumentation, control and automation technology.


In 2006 the line of electronic energy meters with fully integrated bus compatibility started production.

In 2006 Saia Burgess Controls brought to market the world’s first completely web-based touch-panel for automation.


In 2010 reconstruction of the Saia PCD1 means that even the smallest device series has joined the Saia PCD3 and Saia PCD2 in being fully modernized. The 3rd generation of Saia Burgess Controls control devices is now complete. This is characterized by the following equation: Saia PCD® = PLC + IT + Web This formula stands for the seamless

integration of world renowned, open technologies for web and IT on freely programmable, industrial electronics with the same quality and lifecycle as the robust, industrial PLC.

S-Energy – capture, display and log consumption values

Energy management


S-Energy stands for solutions that reduce energy costs and can be made operational immediately. The system includes components for capturing, visualizing and recording electrical energy values.


Bus-compatible energy meters (S-Bus) to capture power consumption and electrical operating data.

Visualize on-site

S-Energy Manager, in the form of a control panel, reads data from connected energy meters and displays it graphically.

Link up with automation

Controllers (PLCs) can access energy data in the S-Energy Manager via S-Bus, Modbus and MPI.

Provide energy data in IT-compatible form

With the S-Energy Logger energy values can be transferred directly from energy meters and S-Energy Managers to SQL databases. S-Energy combines many years of experience in the field of measuring electrical consumption with core competencies in HMI and web technology. Captured consumption data can therefore be accessed via network and internet – requiring just a PC with standard browser for analysis.


Bus-compatible electricity meters – Energy capture for each specific load
Bus-compatible electricity meters determine electrical consumption values directly at the load. The product range includes AC power meters and three-phase meters with measuring ranges up to 6000 A, each with S0 output or serial bus interface (S-Bus, M-Bus and Modbus).

S-Energy-Manager – On-site analysis of consumption values
The S-Energy Manager combines data capture, visualization and logging in one, compact control panel.
