Core Features & Operating Capabilities
- High-Speed Deterministic Control: Designed for real-time turbine governing, speed loop processing, and critical valve positioner control algorithms.
- MicroNet Architecture Integration: Plugs directly into standard MicroNet VME-style backplanes, supporting both simplex and fully redundant system architectures.
- Online Hot-Swappability: Supports live module removal and insertion in redundant subrack configurations without requiring a complete process shutdown.
- Comprehensive Onboard Self-Diagnostics: Continuously monitors CPU health, internal DC power rails, communication link integrity, and thermal thresholds, instantly logging fault flags upon detecting an anomaly.
- Industrial Noise & Vibration Resistance: Built with heavy-duty noise suppression and conformal coating to withstand harsh power plant and off-shore platform environments.
