DS200FHVAG1ADA GE

Technical Parameters & Specifications

Core Advantages & Key Features

• High-Voltage Signal Interface – The DS200FHVAG1ADA provides 4 isolated analog inputs and 2 isolated analog outputs for high-voltage signals (0-300V), enabling direct interface with generators, switchgear, excitation systems, and other 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.

• Longest Distance Capability – Supports up to 8 km (multimode) or 25 km (singlemode), enabling communication with high-voltage equipment located far from the control rack.

• Dual Redundant Fiber Paths – Two independent transceiver ports with automatic failover ensure communication availability.

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

• Advanced Diagnostics – Comprehensive monitoring of link status, optical power, and high-voltage input/output health.

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

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

Typical Applications

• Generator Interface – Connects generator voltage and current signals to the Mark V turbine control system.

• Switchgear Monitoring – Interfaces with high-voltage switchgear for status and control signals.

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

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

• Remote High-Voltage Equipment – Enables communication with high-voltage equipment over long distances.

Field Example: A large power plant integrated DS200FHVAG1ADA boards to connect generator voltage signals to the Mark V turbine control system, replacing copper wiring with fiber optic links to eliminate EMI issues and improve safety.
