General Electric DS200FHVAG2ADA

Technical Parameters & Specifications

Core Advantages & Key Features

• Dual-Channel High-Voltage Interface with Extended Distance – The DS200FHVAG2ADA provides independent high-voltage signal processing for two separate high-voltage equipment sources simultaneously, supporting distances up to 5 km (multimode) or 15 km (singlemode) per channel.

• Dual Fiber Type Support – Selectable per channel via jumpers for multimode or singlemode to match plant infrastructure.

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

• Fiber Optic Gateway – Converts high-voltage signals to fiber optic communication with complete electrical isolation.

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

• Advanced Diagnostics – Optical power measurement, BER monitoring, and link health trending per channel for comprehensive fiber link assessment.

• Dual Redundant Fiber Paths Per Channel – Each channel has two independent transceiver ports with automatic failover.

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

• Extended Temperature Range – -40°C to +70°C for extreme environments.

• Robust Environmental Protection – Enhanced conformal coating and 30µin gold-plated connectors.

• 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 system over long distances.

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

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

• Offshore Platforms – Supports communication across large offshore installations.

• Campus-Scale Installations – Enables high-voltage equipment communication between multiple buildings.

Selection Guidelines & Precautions

• Evaluate Number of High-Voltage Sources – The DS200FHVAG2ADA is ideal when two independent high-voltage equipment sources require interface over long distances.

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

• Evaluate Distance and Fiber Type – Select multimode (up to 5 km) or singlemode (up to 15 km) per channel based on distance and infrastructure.

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

• 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 DS200FHVAG2ADA is the preferred replacement for all earlier FHVAG2 variants. Maintain spares for critical systems with multiple high-voltage equipment.

Summary

The DS200FHVAG2ADA is the most advanced dual-channel fiber optic high-voltage adapter and gateway board in the GE Mark V series, offering independent high-voltage analog I/O (4 inputs, 2 outputs per channel, 0-300V), 8 isolated digital inputs per channel (24-250V), dual fiber type support (multimode/singlemode), extended distance (5 km MM / 15 km SM), optical power monitoring, and 2500 VAC isolation for two separate high-voltage sources. This revision is the preferred replacement for all earlier DS200FHVAG2 variants. The board integrates with DS200CPCAG1A processors. Selection requires evaluation of the number of high-voltage sources, distance, fiber type, and signal requirements.
