GE IS200TBAOH1B

¥999.00

IS200TBAOH1B is a high-capacity Terminal Board within the GE Mark VIe Speedtronic control system, designed as a high-density field termination and signal conditioning interface for analog output signals in turbine control applications. This board provides centralized termination for analog actuators such as control valves, positioners, variable frequency drives, and other analog-controlled field devices, connecting to the Mark VIe main VME-based controller processors via front-panel I/O cables. The IS200TBAOH1B features integrated termination points for analog outputs with built-in signal conditioning including filtering, isolation, and surge protection. It offers 24 analog output channels—a 50% increase over the IS200TBAOH1A—making it ideal for larger turbine systems requiring extensive actuator control.

Advantages & Key Features

  • Higher Channel Density: 24 analog outputs in a single VME slot—50% more than IS200TBAOH1A and triple the density of competing 8-channel modules. Ideal for turbines with extensive control valve and actuator requirements.

  • Flexible Output Configuration: Each channel supports 4–20 mA or 0–10 V outputs via GE ToolboxST software.

  • High Resolution: 16-bit DAC provides precise control for critical turbine parameters.

  • Programmable Filtering: Onboard low-pass filter (1–50 Hz) smooths output signals to reduce mechanical wear on actuators.

  • Comprehensive Diagnostics: Real-time open-circuit, short-circuit, and over/under-range monitoring per channel.

  • Short-Circuit Protection: Each output is protected against short circuits and overcurrent conditions.

  • ToolboxST Integration: Full configuration, calibration, and diagnostics via GE ToolboxST.

  • Drop-In Replacement: Direct replacement for earlier GE analog output terminal boards.

Application Fields

  • Gas & Steam Turbines (GE Frame 6B/7EA/9E/HA): Fuel gas control valves, steam admission valves, inlet guide vane positioners, bypass valves, actuator position control, variable speed drive control, auxiliary system actuators.

  • Combined Cycle Plants: HRSG feedwater control valves, bypass valve positioning, steam temperature control actuators.

  • Compressor Stations: Anti-surge valve control, recycle valve positioning, variable speed compressor control.

  • Aeroderivative Turbines: Fuel control actuators, variable inlet guide vanes, bleed valve control.

Key Advantage: IS200TBAOH1B provides 24 analog outputs—the highest channel density in its class and triple that of competing modules—with flexible output configuration, 16-bit resolution, and comprehensive diagnostics, significantly reducing rack space for large turbine actuator control applications.

Selection Guidelines & Recommendations

  • Output Type: Configure 4–20 mA or 0–10 V per channel in GE ToolboxST.

  • Load Verification: Ensure connected actuators do not exceed load impedance capability (0–750 Ω for current, > 2 kΩ for voltage).

  • Filtering: Use 1–10 Hz for smooth actuator response, 20–50 Hz for faster dynamic control.

  • Controller Firmware: Requires Mark VIe processor firmware v7.0 or later.

  • Spare Strategy: Keep one spare per turbine; lead times 6–10 weeks.

  • Retrofit: Direct replacement—regenerate configuration in GE ToolboxST for 24-channel mapping.

Important Cautions

  1. No Hot-Swap: De-energize rack before insertion/removal.

  2. Output Polarity: Observe correct polarity for current loops.

  3. Short-Circuit Protection: While protected, sustained short circuits may cause thermal shutdown.

  4. Grounding: Connect AGND to Mark VIe system ground at single star point.

  5. Shield Termination: Ground output cable shields only at cabinet end.

  6. ESD Handling: Use grounded wrist straps; field repair not possible.

  7. Filtering Trade-Off: Higher filtering provides smoother output but introduces signal delay.

  8. Channel Mapping: With 24 channels, verify wiring maps to correct ToolboxST channel assignments.

  9. Power Supply: Ensure rack power supply provides adequate current for all active outputs (20 mA × 24 channels = 480 mA max).
