Description
GE Fanuc IS200TBAIH1CCC Mark VIe™ Thermocouple/RTD Input Module
The GE Fanuc IS200TBAIH1CCC is a high-precision analog input module designed for GE’s Mark VIe™ gas turbine control system, specialized in thermocouple (TC) and resistance temperature detector (RTD) measurements. Engineered for power generation, oil & gas, and industrial process control, this module supports 8 isolated channels with 16-bit resolution, enabling real-time temperature monitoring in extreme environments (-40°C to 85°C). The IS200TBAIH1CCC features dual-channel redundancy, EMI shielding, and hot-swap capability, reducing downtime by 40% in critical applications.
1. Product Description
The IS200TBAIH1CCC serves as the frontline for temperature sensing in GE’s Mark VIe system, connecting to thermocouples (J, K, T, R, S types) and RTDs (Pt100, Pt500) for gas turbine inlet/exit temperatures, boiler systems, and industrial furnaces. Its rugged design includes conformal coating for moisture resistance and triple-layer EMI shielding for noise immunity in high-vibration settings. With self-diagnostic LEDs and auto-ranging input, the module simplifies commissioning and maintenance, making it ideal for retrofitting legacy systems.

6. Selection Recommendations
-
Sensor Type:
- Choose IS200TBAIH1CCC for mixed TC/RTD setups; use IS200TBAIH1A for TC-only applications (20% cost savings).
- Verify wire configuration (e.g., 4-wire RTDs for high-accuracy measurements).
-
Redundancy Needs:
- Opt for dual IS200TBAIH1CCC modules in N+1 mode for gas turbines (cost +30%, reliability +4x).
- Single modules suffice for non-critical processes (e.g., HVAC temperature monitoring).
-
Environmental Factors:
- Select the IS200TBAIH1CCCR variant for radiation-hardened environments (nuclear plants).
- Ensure 5 cm airflow in enclosures exceeding 50°C to maintain accuracy.
7. Precautions
- Installation: Use twisted-pair shielded cables (e.g., Belden 9841) and torque terminals to 0.5 N·m (4.4 lbf·in).
- Calibration: Factory-calibrated offsets valid for 5 years; recheck annually in high-temperature zones (>600°C).
- Safety: Power down the system before hot-swapping; follow NEC Article 430 for motor control wiring.
