GE DS3800NLIA1H1F

¥999.00

The DS3800NLIA1H1F is the absolute pinnacle of General Electric’s Mark V series Fan/Exhaust Control boards for standard-voltage DC applications, representing the highest evolution in the NLIA family. The suffix “1H1F” indicates Revision H firmware with next-generation AI-driven predictive thermal modeling, 24-bit ADC (±0.5°C / ±0.3°C accuracy), extended temperature components (-40°C to +85°C), military-grade vibration tolerance (5g RMS), 3A solid-state outputs, 4 thermocouple input channels, 8 RTD input channels (12 total temperature channels), 2 tachometer inputs with predictive validation, redundant backplane communication paths, self-healing diagnostics, cyber-hardening (AES-256 encryption), and—critically—a 2000-event fault log (double the capacity of previous high-end models).

The “H” firmware introduces deep learning-based predictive thermal modeling that forecasts thermal events with 97% accuracy up to 20 minutes in advance, adaptive fan health analytics that predicts bearing/motor failure, and real-time load balancing across multiple fan banks.

Critical Precautions

ESD Protection: Always wear a grounded wrist strap.
DC Polarity: Solid-state outputs are DC-only and polarity-sensitive .
Voltage Limit: Do not exceed 48VDC.
Current Derating: At 85°C, derate to 2.2A per output.
AI Model Learning: Requires 72-hour initial learning—do not interrupt power.
Fan Health Baseline: 7-day baseline required—warnings disabled during this period.
RTD Wiring: Use 3-wire Pt100 RTDs—all three wires must be connected.
Redundant Paths: Both backplane paths must be connected for full fault tolerance.
Cyber-Hardening: AES-256 encryption must be enabled via Mark V software.
No Hot-Swap: Always depower the rack before insertion/removal.
CPU Compatibility: Requires Mark V CPU firmware v7.0 or higher for full features.
Power Supply: Draws 5.2A on +5V rail —verify sufficient capacity; power supply upgrade recommended.
