Overview

The ABB 216MB66 (HESG324510M1 / HESG324511M1) is a high-performance equipment rack designed for ABB’s REG216 digital generator protection system. It provides the mechanical and electrical backbone for housing essential modules, including input transformers, relay outputs, and communication interfaces.

The 216MB66 integrates a parallel bus system (B448C) for fast, reliable internal data exchange between modules. Its modular design allows scalable expansion, making it ideal for applications that demand high reliability, easy maintenance, and flexible configuration.

For example, in a thermal power plant, the 216MB66 can host all REG216 modules required to monitor generator voltage, current, and frequency, while coordinating protection logic and trip signals.

Technical Data

Typical Applications

• Generator Protection Systems: Hosts REG216 modules for voltage, current, and frequency monitoring.

• Power Plant Automation: Provides a centralized platform for protection and control hardware.

• Substation Control Panels: Organizes and interconnects I/O and relay modules for grid protection.

• Industrial Process Control: Supports modular expansion of safety and control systems.

• Retrofit and Upgrade Projects: Replaces legacy racks with modern, compact, and bus-integrated solutions.

The 216MB66 is selected for its ease of wiring, compact footprint, and compatibility with ABB’s modular protection architecture.
