DS200FHVAG2A GE

Technical Parameters & Specifications

Core Advantages & Key Features

• Dual-Channel High-Voltage Interface – The DS200FHVAG2A provides independent high-voltage signal processing for two separate high-voltage equipment sources simultaneously, enabling a single board to serve multiple generators, switchgear panels, or excitation systems.

• 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 with complete electrical isolation.

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

• Extended Distance Capability – Supports up to 3 km per channel (increased from 2 km).

• Enhanced Diagnostics – The Revision A adds bit error rate (BER) monitoring and signal quality indication per channel for proactive maintenance.

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

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

• Robust Environmental Protection – Enhanced conformal coating and 30µin 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 North American power plant integrated DS200FHVAG2A boards to connect both main generator and auxiliary generator voltage signals to the Mark V system, reducing board count by 50% compared to single-channel boards, with improved diagnostic capabilities enabling proactive maintenance.

Selection Guidelines & Precautions

• Evaluate Number of High-Voltage Sources – The DS200FHVAG2A 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 Distance Requirements – Supports up to 3 km per channel. For longer distances, consider the FHVAG1 series.

• 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 DS200FHVAG2A is the preferred replacement for the base DS200FHVAG2. Maintain spares for critical systems with multiple high-voltage equipment.

Summary

The DS200FHVAG2A is an enhanced 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 with extended distance (3 km) and BER monitoring. This revision is the preferred replacement for the base DS200FHVAG2. The board integrates with DS200CPCAG1A processors. Selection requires evaluation of the number of high-voltage sources, signal requirements, distance, and rack space.
