Bailey

Bailey Controls was established in 1916 by the US inventor Ervin G. Bailey and became a leader in distributed process controls.

In 1989 it merged with Italy's Elsag Group to form Elsag Bailey Process Automation and merged again in 1998 to reside within ABB.

Bailey manufactures a number of programmable logic controllers, I/O modules, termination units, power supplies, and loop controllers under the Network 90 and INFI Control Modules product lines.
