Overview
The ABB Bailey Controls A10 Operator Keyboard is a legacy operator interface input device designed for ABB Bailey Infi 90 and Net 90 distributed control systems (DCS). Part number 6638514A1, revision A10, this keyboard served as the primary human-machine interface (HMI) control input for process automation and manufacturing facilities using Bailey-era DCS platforms. Bailey Controls was acquired by ABB in 1998, and this equipment remains in use across process industries including chemicals, power generation, water treatment, and discrete manufacturing.
