Overview

The ABB HESG324087R2AE2 is a REG216 series control module designed for generator protection and power system applications. It acts as a central processing or interface unit, coordinating data from input transformers, relay outputs, and communication modules. The module executes protection logic, manages fault signals, and interfaces with supervisory systems such as SCADA or DCS.

Built to withstand industrial environments, the HESG324087R2AE2 supports DIN-standard mounting, IP30 protection, and multi-channel signal handling. It is commonly used in power generation, substations, and industrial automation networks, and is ideal for retrofit projects to replace legacy protection systems with modern digital control.

For example, in a gas-fired power station, the module can process differential current signals and trigger trip commands to isolate generators during fault conditions.
