216MB66 ABB Equipment Rack for REG216 Generator Protection System

Description

TheABB 216MB66 (HESG324510M1 / HESG324511M1)is ahigh-performance equipment rackdesigned for ABB’sREG216 digital generator protection system. It provides themechanical and electrical backbonefor housing essential modules, includinginput transformers, relay outputs, and communication interfaces. The 216MB66 integrates aparallel bus system (B448C)forfast, reliable internal data exchangebetween modules. Its modular design allowsscalable expansion, making it ideal for applications that demandhigh reliability, easy maintenance, and flexible configuration. For example, in athermal power plant, the 216MB66 can host all REG216 modules required to monitor generator voltage, current, and frequency, while coordinating protection logic and trip signals.
