ABB GCC960C102 3BHE033067E0102 Generator Control Communication Board

The ABB GCC960C102 3BHE033067E0102 is a dedicated communication and interface control board for ABB generator excitation and turbine control systems. It processes real‑time generator operating data, completes high‑speed data interaction between the main controller, excitation unit and peripheral monitoring equipment, and undertakes signal conversion and data transmission tasks for power generation unit closed‑loop control.

This plug‑in circuit board is equipped with multiple high‑speed differential signal interfaces and built‑in hardware fault monitoring circuits, adapting to harsh electromagnetic interference environments of power plants. Original production has been discontinued. It is widely used as aftermarket spare parts for thermal power, hydro‑power plant generator control cabinet maintenance and control system retrofit projects.
