Description
The ABB GCC960C103 (identified by part numbers 3BHE033067R0103 and 3BHE033068P106) is a sophisticated control and communication board primarily utilized in ABB’s Power Electronics systems. It is a core component in high-power excitation systems (such as UNITROL 6000) and static frequency converters (SFC), providing the computational power and interface logic required for synchronous machine control.
Product Technical Description
The GCC960C103 acts as a high-performance controller designed for real-time regulation. It handles complex mathematical models for motor or generator control, including voltage regulation, reactive power compensation, and synchronization logic.
- Integrated Architecture: Combines a powerful digital signal processor (DSP) with FPGA logic to handle high-speed pulse width modulation (PWM) and fiber-optic communication.
- Fiber-Optic Interface: Uses optical links to communicate with power modules (IGBT/Thyristor stacks) to ensure total galvanic isolation and immunity to electromagnetic interference (EMI).
- System Integration: Often used as the “Master” or “Follower” unit in redundant control configurations within the AC 800PEC control platform family.
- Reliability: Designed for heavy industrial use in power plants and marine propulsion systems where downtime is not an option.

Common Questions & Answers (Q&A)
Q: What is the difference between 3BHE033067R0103 and 3BHE033068P106? A: Usually, the R-number (R0103) refers to the complete functional assembly (the board plus firmware/packaging), while the P-number (P106) refers to the bare printed circuit board or a specific sub-component of the assembly.
Q: Does this board require specific firmware before installation? A: Yes. The GCC960C103 is a programmable controller. It must be loaded with the application software specific to your excitation system or converter project using the ABB Control Builder tool.
Q: Can I hot-swap this board? A: No. In most UNITROL or SFC configurations, removing the main control board while the system is under load will cause an immediate trip. Power should be disconnected before removal.
Q: Why are there so many fiber-optic ports? A: These ports allow for high-speed, noise-free communication with multiple peripheral units, such as Measurement Boards (AI), Gate Driver Boards, and other GCC units in a redundant setup.
