Product Summary
The IS200EDEXG1BQ is a critical De-Excitation Bridge and Protection Board. It safely manages field energy dissipation in the EX2100 system. This board utilizes a silicon-controlled rectifier (SCR) for reliable de-excitation. It provides a vital backup function if the EXTB controller fails. This ensures maximum system safety and operational uptime.
Expert Technical Evaluation & Performance Review
The IS200EDEXG1BQ board functions as a robust safety mechanism. Its primary role is to safely discharge the generator field. The board relies on a silicon-controlled rectifier for this task. The SCR creates a conduction path when required. This path runs through the field discharge inductor. The inductor allows the field current to flux and dissipate safely. This process disperses the stored magnetic field energy. The entire operation prevents dangerous voltage spikes from occurring.
A key engineering feature is its redundant firing mechanism. The SCR normally fires upon a command signal. If that primary signal fails, a backup system activates. The board will fire the SCR on overvoltage. This happens when the anode-to-gate voltage becomes too high. It surpasses the breakover voltage of the diode string. This string connects directly between the gate and anode. This design guarantees de-excitation even with a control failure.
The board requires a 24 VDC power supply for operation. This power is sent to the de-excitation module. The module then manages the SCR firing sequence. The IS200EDEXG1BQ model is located in an auxiliary cabinet. This placement keeps it close to the main power components. It connects to the EMIO and EXTB boards for proper function. The EXTB board normally handles power and control tasks. The EDEX board provides a crucial backup for de-excitation.
This board uses six configurable jumpers for setup. These are labeled JP1 through JP6. It connects to the system via two D-pin connectors. The board weighs exactly 3 lbs. 6 oz. for handling. It is part of the GEH-6632 manual series. This series covers the entire Innovation Series EX2100 system. The board acts as the last line of defense for the generator.
