   • Optional IRIG-B time synchronization for precise event logging.
3. User-Friendly Interface:
   • Intuitive LCD display with multilingual menu navigation for configuration and diagnostics.
   • Front-panel LED indicators for real-time status and fault alerts.
4. Robust Hardware Design:
   • Operates in harsh environments with a wide temperature range (-25°C to +70°C).
   • High immunity to electromagnetic interference (EMI) and vibrations.
5. Flexible Configuration:
   • Programmable logic (PLC-like functionality) for custom automation sequences.
   • Configurable I/O modules for digital inputs, outputs, and analog signals.
6. Event Recording and Diagnostics:
   • Stores fault records, waveforms, and event logs for post-incident analysis.
   • Self-diagnostics for hardware health monitoring.
