Description

The ABB GFD563 (Order Code: 3BHE046836R0103) is a high-performance fiber-optic Ethernet communication module designed for use with ABB’s AC 800M programmable automation controllers (PACs) within the System 800xA distributed control architecture. Specifically engineered for mission-critical power systems, the GFD563 enables deterministic, high-speed data exchange between protection relays, merging units, bay controllers, and supervisory systems in accordance with IEC 61850 standards.

As part of ABB’s Protection and Substation Automation portfolio, the GFD563 supports key IEC 61850 services including GOOSE (Generic Object Oriented Substation Event) and Sampled Values (SV) over fiber, facilitating ultra-fast peer-to-peer communication essential for busbar protection, breaker failure schemes, and synchronized phasor measurements. The module features dual independent 100BASE-FX fiber ports, enabling ring or star topologies with hardware-level redundancy—critical for maintaining network availability during cable faults or switch failures.

Housed in a rugged, conduction-cooled package compatible with standard AC 800M I/O racks, the GFD563 operates reliably in electrically noisy environments such as high-voltage substations, where copper-based Ethernet would suffer from ground loops or electromagnetic interference (EMI). Its galvanic isolation and immunity to lightning-induced surges make it ideal for outdoor or switchyard installations when used with appropriate enclosures.

⚙️ Technical Specifications

✅ Main Features and Advantages

Native IEC 61850 Integration: The GFD563 is optimized for digital substation applications, allowing AC 800M to act as a Logical Node or Bay Controller that directly subscribes to Sampled Values from merging units and publishes GOOSE trip commands—eliminating protocol converters and reducing system latency to<4>

Robust Fiber-Optic Communication: By using optical fiber instead of copper, the GFD563 provides complete electrical isolation between devices, preventing ground potential rise issues common in multi-grounded substation yards. This also ensures immunity to EMI from circuit breaker operations or nearby radio transmitters.

High Availability Architecture: With two independent fiber ports, the GFD563 supports redundant network topologies (e.g., ring networks using RSTP or proprietary ABB redundancy). In the event of a fiber cut or switch failure, traffic automatically reroutes—ensuring continuous protection functionality.

Seamless System 800xA Integration: Configuration is performed in Control Builder M, where engineers can map IEC 61850 data objects directly to AC 800M application logic. Diagnostics (link status, error counters) are visible in real time via the 800xA operator workplace.
