ABB GCC960C103 3BHE033067R0103 Generator Control Communication Interface Board

The ABB GCC960C103 3BHE033067R0103 is a specialized plug‑in communication interface board for ABB turbine‑generator and excitation control systems. It handles real‑time operational data exchange between main controller, excitation unit and peripheral monitoring devices, and undertakes signal conversion and command transmission for generator closed‑loop regulation in power plant automation.

This circuit board is equipped with multiple differential signal interfaces and built‑in hardware fault detection circuits, which can adapt to harsh high‑electromagnetic‑interference environment in power‑generation workshops. Original production has been discontinued. It serves as aftermarket spare parts for thermal power and hydropower generator control cabinet maintenance and control‑system upgrade projects.
