Technical Specifications:
  • Series:​ Mark V / Mark VI Speedtronic I/O Module
  • Channels:​ 16-channel analog input
  • Signal Types:​ 4–20 mA / 0–10 V DC (configurable)
  • Resolution:​ 16-bit A/D conversion
  • Sampling Rate:​ 100 ms/channel (all channels)
  • Accuracy:​ ±0.1% full scale
  • Isolation Voltage:​ 500 V DC (between channels)
  • Communication:​ GE control system internal bus (Genius / Series 90-70)
  • Supply Voltage:​ 5 V DC (bus-powered)
  • Operating Temperature:​ 0°C to +60°C
  • Storage Temperature:​ -40°C to +85°C
Features:
  • High-precision 16-bit A/D conversion
  • Channel-to-channel isolation to eliminate crosstalk
  • Cold junction compensation (for thermocouple input models)
  • Wire-break detection and over-limit alarm
  • Hot-swappable module support (Mark VIe system)
  • Status LED indicating per-channel working state
Material Composition:
  • PCB:​ 6-layer FR-4 glass fiber board with gold finger connector
  • Module Housing:​ Galvanized steel plate + conductive paint (EMC shielding)
  • Connector:​ Military-grade high-density connector
  • A/D Chip:​ Industrial-grade Δ-Σ converter
Working Principle:
Analog signals pass through signal conditioning circuitry (filtering, amplification, isolation) and enter the 16-bit Δ-Σ A/D converter. Conversion results are optically isolated and sent to the control system internal bus for CPU processing in gas turbine speed control, temperature monitoring, and load regulation.
Applications:
Gas turbine power generation, combined-cycle power plants, industrial drive turbines, oil and gas transmission.
Installation Requirements:
  • Insert into designated Mark V/VI control cabinet slot
  • Tighten module fixing screws to 1.5 N·m torque
  • Use shielded twisted-pair cables for signal wiring, single-point grounding
Precautions:
  • Strictly prohibit hot-swapping (Mark V system); Mark VIe supports hot-swap
  • Maintain ≥ 100 mm separation between signal and power cables
  • Perform accuracy calibration every 5 years
  • Store backup modules in anti-static packaging, humidity ≤ 60% RH
