GE IS200EDFFH1A EX2100e, DC Fanned Feedback Card

الوصف

The GE part number IS200EDFFH1A is an EX2100e DC Fanned Feedback Card. It’s a key component of GE’s Mark VIe Excitation Control Systems. Its primary function is to measure the DC voltage and current of a generator’s field, providing crucial feedback to the control system. ⚡

Function and Key Features

This board is part of a digital control system that regulates the output voltage of a generator. It’s an upgrade from the legacy EX2100 system, designed for higher-reliability, high-power applications.

• DC Field Voltage and Current Measurement: The board measures the DC voltage and current that are being supplied to the generator’s rotor field. This data is essential for the system to precisely regulate the generator’s output.
• “Fanned” Feedback: The “Fanned” designation indicates that the board’s design, including its components and layout, is optimized for use in a fanned or forced-air cooling environment. This allows for improved thermal management and higher performance in high-power applications.
• System Integration: The EDFF board works in conjunction with the main control card (like a DSPX) and other I/O boards to form a complete excitation control system.
• Robust Design: Like all GE industrial control components, it’s built to withstand the harsh conditions of a power plant, including high voltages, vibrations, and electromagnetic interference.

Applications

The IS200EDFFH1A is a key component in power generation facilities that have upgraded to the Mark VIe Excitation Control System. It’s used for:

• Excitation Control: It provides the core data necessary for the EX2100e system to precisely control the generator’s voltage and reactive power.
• Protection and Diagnostics: The board is a crucial part of the system’s protection logic, allowing it to detect and respond to faults such as overcurrents or voltage spikes in the DC field circuit.
