Key Features
- High-Isolation Design
- Galvanic isolation prevents ground loops in noisy electrical environments.
- Generator Protection
- Integrates over-voltage/under-frequency trip logic for excitation systems.
- Hot-Swappable
- Replaceable without turbine shutdown (reduces downtime).
- Diagnostic LEDs
- Per-channel status monitoring (fault, comms, power).
- Environmental Robustness
- Conformal coating for humidity/dust resistance (“AED” suffix).
Functional Role
- Primary Function: Converts exciter field signals (e.g., generator voltage/current) for the Mark VIe controller.
- Critical Safeguard: Triggers automatic de-excitation during grid faults to protect generators.
