• Power Supply: 24V DC
• Power Consumption: Less than 10W
• Dimensions: 150 mm x 100 mm x 20 mm
• Weight: 250g
• Mounting Method: DIN rail mounting
• Communication Interfaces: RS485, Ethernet
• Operating Temperature Range: -40°C to 85°C
• Storage Temperature Range: -40°C to 85°C
• Humidity Tolerance: 5% to 95% non-condensing

Functional Characteristics

• High Precision and Stability: Utilizes industrial-grade ADCs and shielding designs to maintain signal stability, even in the presence of strong EMI from igniters or excitation systems. Real-world tests show temperature drift of less than 0.5°C over a week of continuous operation at 50°C.
• Independent Channel Processing: Each of the 32 channels features independent signal conditioning and CJC, ensuring that a fault in one channel does not affect others.
• Redundancy Support: Seamlessly integrates with GE’s Triple Modular Redundant (TMR) architecture, allowing for the simultaneous connection of the same thermocouple signal to three independent IS200TDBTH6ACD modules. The controller then uses a two-out-of-three voting mechanism to prevent erroneous trips.
• Cost-Effective Design: Eliminates the need for external temperature transmitters, reducing wiring complexity, calibration efforts, and potential failure points. This native integration enhances system reliability and simplifies maintenance.
• User-Friendly Configuration: Comes with clear documentation and easy-to-use programming tools, facilitating quick setup and operation.

Application Scenarios

• Gas Turbine Applications: Monitors critical temperatures at the compressor outlet, combustion chamber flame tubes, and turbine first-stage blades in GE 9FA, 7HA, and other heavy-duty gas turbines.
• Combined Cycle Power Plants: Tracks exhaust gas temperatures in Heat Recovery Steam Generators (HRSGs) to prevent overheating and tube rupture.
• LNG Compressor Stations: Provides real-time monitoring of motor bearing and exhaust temperatures to avoid overheating shutdowns.
• Waste-to-Energy Plants: Withstands high-dust and corrosive environments while monitoring furnace temperatures to ensure complete combustion and minimize emissions.
• Industrial Boilers and Furnaces: Used in various industries to monitor combustion temperatures, ensuring efficient operation and preventing equipment damage.
