Bailey introduced the 820 Control System as a product line with the "split" architecture in the early 7ies. The 820 Control System Line was specifically designed for Power Stations; later on Bailey introduced  the 861 Series whose application was specifically designed for Power Stations' Sequential Control and Burner Management Systems in association with the 820 Control System, which is the modulating control for the Boiler. The second generation of the electronic control system introduced by Bailey on the market was the 7000 Control System Line, both in "split" and unitized architecture. The 7000 Control System Line was designed particularly for the chemical and oil and gas industry.  The Network90 Line was introduced by Bailey in 1990, and was the first Bailey microprocessor based Control System Line. The Network 90 line was improved and re-designed some years later as INFI90 Control System Line, which is the last Bailey Control Branded System Line, before merging of Bailey in ABB Group. The INFI90 Line is the base architecture for Symphony and Harmony Line that are the current ABB Control System lines . EXA can provide a large range of Bailey and Bailey - ABB Modules.
