The ABB Bailey IMQRS22 is an advanced Quad Redundant System (QRS) interface module designed for the INFI 90 distributed control system (DCS). It is engineered to support high-availability automation architectures where continuous operation, fault tolerance, and system synchronization are critical.
Within industrial control environments, the IMQRS22 plays a key role in coordinating redundant controller paths and ensuring seamless switchover between system channels. It is widely used in power generation, oil & gas, and heavy process industries, where downtime is not acceptable.
