Description
Product Description
GE IS230TBAIH2C is a TBAI analog I/O terminal board for Mark VI Speedtronic gas turbine control systems, supporting simplex and triple modular redundant (TMR) architectures with VAIC processors. GE IS230TBAIH2C integrates 10 universal analog inputs (2/3/4-wire transmitters, 4–20 mA/0–10 V) and 2 configurable analog outputs (0–20 mA/0–200 mA), with built-in noise suppression for surge/high-frequency immunity. GE IS230TBAIH2C uses three DC-37 pin connectors for I/O processor links: JR1 for simplex, and JR1/JR2/JR3 for TMR (R/S/T control signal fanning). GE IS230TBAIH2C features hardware jumpers for output current range (20 mA/200 mA) and TMR current summation via measuring shunts, ensuring fault-tolerant signal processing. GE IS230TBAIH2C is a genuine GE board optimized for turbine control, conditioning LVDT, servo valve, vibration, and process signals for precise regulation. GE IS230TBAIH2C centralizes analog I/O termination and signal conditioning, reducing wiring complexity and improving reliability in power generation and turbine automation.

Application Fields and Cases
GE IS230TBAIH2C is used in gas turbine control, combined-cycle power plants, and industrial turbine automation:
- Gas Turbine Control: Conditions LVDT, vibration, temperature, and fuel flow signals for speed and load regulation.
- Combined-Cycle Power Plants: Integrates with steam turbine controls for coordinated plant operation and grid stability.
- Turbine Retrofits: Upgrades Mark VI systems with enhanced analog I/O and TMR support for legacy turbine fleets.
Case Example: A Middle Eastern combined-cycle plant used GE IS230TBAIH2C to upgrade 4 Mark VI TMR systems, replacing obsolete analog I/O boards. GE IS230TBAIH2C added 40 analog inputs and 8 outputs for turbine vibration, exhaust temperature, and fuel valve control, reducing signal noise by 40% and improving control loop stability. Post-installation, the plant achieved 99.99% turbine availability and cut maintenance time by 25% via simplified I/O termination.

Selection Recommendations and Precautions
Selection Recommendations
- Choose GE IS230TBAIH2C for Mark VI Speedtronic systems needing simplex/TMR analog I/O with turbine-specific signal conditioning.
- Match jumpers to output current (20 mA/200 mA) and redundancy mode (simplex/TMR) for your application.
- Use shielded cables for analog signals to minimize noise in turbine environments.
- Deploy in TMR mode for safety-critical turbine control loops to maximize availability.
Precautions
- Ensure GE IS230TBAIH2C is powered from the Mark VI backplane (5 VDC ±5%) to avoid damage.
- Follow TMR connector guidelines (JR1/JR2/JR3) for proper signal fanning and current summation.
- Use ESD-safe handling during installation to protect noise suppression circuitry.
- Verify jumper settings for output current range before commissioning to prevent actuator damage.
- Avoid exceeding operating temperature (-25°C to +70°C) to maintain signal accuracy and reliability.
