Description
GE Fanuc IS200STCIH2A High-Accuracy Temperature Input Module
The IS200STCIH2A is a 16-channel analog input module designed for GE Fanuc’s Mark VIe/Mark VI gas turbine control systems, specialized in precision temperature measurement for industrial processes. Engineered to interface with thermocouples (J/K/T types) and RTDs (Pt100/1000), this module delivers ±0.1% accuracy and 2.5kV isolation, ensuring reliable data acquisition in harsh environments like power plants, refineries, and aerospace test facilities.
1. Product Overview
The IS200STCIH2A serves as the backbone for temperature monitoring in GE’s Mark VIe platform, supporting real-time control of gas turbines, steam generators, and combustion systems. Its auto-ranging input adapts to 0–50mV (thermocouples) or 0–50Ω (RTDs), while cold-junction compensation eliminates thermal drift. With -40°C to +85°C operating range and IP20-rated design, the module withstands extreme vibrations and EMI common in rotating machinery.

3. Key Advantages
- Precision Measurement: ±0.1% accuracy reduces turbine fuel waste by 2% (case study: Middle Eastern power plant saved $1.2M/year).
- EMI Immunity: Triple-layer shielding minimizes noise in high-voltage environments, achieving 99.99% signal integrity in aerospace tests.
- Hot-Swap Capability: Field-replaceable design cuts downtime by 70% compared to non-isolated modules.
4. Applications & Use Cases
- Power Generation: Monitors turbine blade temperatures in GE Frame 7FA units, enabling predictive maintenance (U.S. plant extended overhaul intervals by 20%).
- Aerospace: Tests jet engine thermal cycles in simulation rigs, supporting ±0.5°C stability for 10,000+ hours (European aerospace lab).
- Oil & Gas: Tracks subsea pipeline temperatures in Arctic fields, withstanding -40°C start-ups and 85°C summer peaks (Norwegian offshore platform).
Case Study: A Japanese combined-cycle plant deployed IS200STCIH2A for 200+ RTDs, reducing temperature measurement errors by 60% and improving load-following efficiency by 15%.

5. Competitor Comparison
- Channel Density: 16 vs. 12 channels in comparable modules, saving 25% rack space.
- Cold-Junction Accuracy: ±0.5°C vs. ±1.0°C in legacy models, critical for thermocouple applications.
- Temperature Range: Operates at +85°C vs. +70°C industry standard, ideal for engine bay installations.
6. Selection Recommendations
- Sensor Type: Use IS200STCIH2A for mixed thermocouple/RTD setups; choose IS200STCIH1A (12-channel) for budget constraints.
- Redundancy: Pair with IS200STCIH2A-EC for dual-channel redundancy in turbine safety systems.
- Environment: Opt for IS200STCIH2A-H (IP65-rated) for outdoor/washdown areas (e.g., biomass plants).
7. Installation & Maintenance Notes
- Wiring: Use twisted-pair shielded cables (AWG 24–18) for RTDs; terminate thermocouples with Type-K connectors.
- Calibration: Annual factory calibration via GE’s ControlST software ensures long-term accuracy.
- Cooling: Maintain 10mm airflow clearance; add heat sinks for ambient >60°C in enclosed cabinets.
