The ABB Bailey NQRC01 Quad Redundancy Controller Module is a high-reliability control and coordination component designed for the ABB Bailey INFI 90 / Net 90 Distributed Control System (DCS). It is specifically engineered to manage redundancy logic between multiple control processors, ensuring uninterrupted operation even in the event of hardware failure.
In mission-critical industrial environments, system downtime is not an option. The NQRC01 enhances system resilience by continuously monitoring redundant controller paths and performing automatic or coordinated switchover actions when faults are detected. This ensures stable process continuity in complex automation networks.
It is widely deployed in power generation, petrochemical plants, and large-scale process industries where fault tolerance and deterministic control behavior are essential.
