Description
GE IS200TTURH1C
Technical Specifications:
- Brand: General Electric (GE)
- Model: IS200TTURH1C
- Product Type: Thermocouple Input Board
- Sensor Type: J, K, or E-type thermocouple compatible
Functional Features:
- Multi-Channel Acquisition: Reads dozens of thermocouples simultaneously to map the exhaust temperature profile.
- Cold Junction Compensation: Precision internal temperature sensing to ensure accurate thermocouple readings regardless of panel temperature.
- Burnout Detection: Identifies open or shorted thermocouple circuits and flags them as faults rather than valid temperature readings.
Application Scenarios:
Critical for gas turbine and steam turbine exhaust temperature monitoring, combustion control, and over-temperature protection.
Performance Parameters:
- Measurement Accuracy: Tight tolerance (e.g., ±1°C) to ensure optimal combustion efficiency and turbine blade life.
- Update Rate: High-speed sampling to capture rapid temperature transients during startup or load rejection.
Material Composition:
Precision low-noise analog front-end components, shielded internal routing, and high-temperature resistant PCB materials.
Structural Characteristics:
Features shielded thermocouple connectors on the front or rear, with dedicated grounding points to prevent ground loops.
Working Principle:
Amplifies the microvolt-level signals from thermocouples, applies cold junction compensation, digitizes the signals, and transmits the temperature data to the main processor via the backplane.
Installation Requirements:
Use only shielded, twisted-pair thermocouple extension wire. Ground the shield at the board end only to prevent ground loops.
Usage Precautions:
Never use standard copper wire for thermocouple connections. Ensure all unused channels are properly terminated or configured as disabled in the software.
