General Electric Mark V Speedtronic DS200FHVAG2

Technical Parameters & Specifications

Core Advantages & Key Features

• Dual-Channel High-Voltage Interface – The DS200FHVAG2 provides independent high-voltage signal processing for two separate high-voltage equipment sources, enabling a single board to serve multiple generators, switchgear panels, or excitation systems simultaneously.

• High-Voltage Signal Interface – Provides 4 isolated analog inputs and 2 isolated analog outputs per channel (0-300V), enabling direct interface with high-voltage equipment.

• Fiber Optic Gateway – Converts high-voltage signals to fiber optic communication, providing noise-immune, long-distance transmission to the Mark V control system with complete electrical isolation.

• High Isolation Voltage – 2500 VAC isolation between high-voltage circuits and logic/fiber optics ensures operator and processor safety.

• Dual Redundant Fiber Paths Per Channel – Each channel has two independent transceiver ports with automatic failover, ensuring communication availability for each high-voltage source.

• Digital I/O – 8 optically isolated digital inputs per channel (24-250V) for status signals from high-voltage equipment.

• Independent Channel Diagnostics – Separate diagnostic LEDs and monitoring for each channel, enabling quick troubleshooting.

• Robust Environmental Protection – Conformal coating and gold-plated edge connectors ensure reliable operation in humid, dusty, or corrosive environments.

• Plug-and-Play Compatibility – Integrates with DS200CPCAG1A processors and other Mark V boards.

Typical Applications

• Multiple Generator Interface – Connects two generators to the Mark V turbine control system simultaneously.

• Generator + Switchgear – Interfaces a generator and associated switchgear on separate channels.

• Excitation System Communication – Connects multiple excitation systems to the turbine control network.

• High-Voltage Protection Systems – Provides safe isolation for protection relay communication from two sources.

• Redundant High-Voltage Monitoring – Supports redundant monitoring of critical high-voltage equipment.

Field Example: A large power plant integrated DS200FHVAG2 boards to connect both main generator voltage signals and auxiliary generator signals to the Mark V system, reducing board count and rack space by 50% compared to using two single-channel boards.

Selection Guidelines & Precautions

• Evaluate Number of High-Voltage Sources – The DS200FHVAG2 is ideal when two independent high-voltage equipment sources require interface. Use it instead of two single-channel boards to save rack space.

• Verify High-Voltage Signal Requirements – Ensure input/output voltage ranges (0-300V) match the connected high-voltage equipment.

• Check Isolation Needs – Provides 2500 VAC isolation for operator and processor safety.

• Distance Limitation – Supports up to 2 km per channel. For longer distances, consider FHVAG1 series with extended range.

• Fiber Type – Multimode fiber only. For singlemode applications, consider other boards.

• Proper High-Voltage Wiring – Follow all high-voltage safety practices and local codes.

• Grounding – Proper grounding is critical for high-voltage isolation and signal integrity.

• Firmware Compatibility – Compatible with DS200CPCAG1A and other Mark V processors.

• Spare Parts Strategy – The DS200FHVAG2 serves a specific application niche requiring dual-channel high-voltage interface. Maintain spares for critical systems with multiple high-voltage equipment.

Summary

The DS200FHVAG2 is a dual-channel fiber optic high-voltage adapter and gateway board for GE Mark V systems, providing independent high-voltage analog I/O (4 inputs, 2 outputs per channel, 0-300V), 8 isolated digital inputs per channel (24-250V), and fiber optic communication for two separate high-voltage sources. It enables safe, noise-immune communication between multiple high-voltage equipment and the turbine control system. The board integrates with DS200CPCAG1A processors. Selection requires evaluation of the number of high-voltage sources, signal requirements, distance, and rack space.
