Structure and Composition

Signal Input Layer

• Supports thermocouples (with cold junction compensation), RTDs (three-wire), and 4-20mA inputs; signal types are selected via jumpers.
• Built-in low-pass filtering and surge protection (TVS diodes).

Signal Conditioning Layer

• Equipped with high-precision instrumentation amplifiers (INA) and 16-bit ADC (Analog-to-Digital Converter) for signal linearization and digitization.
• Uses DC/DC isolated power supplies to prevent ground loop interference.

Output and Communication Layer

• Outputs 0-10V or 4-20mA standard signals, transmitted to the control system via the Mark I/Mark II backplane.
• Front-panel LED indicators display power/fault status.

Key Features and Advantages

• High-precision signal conversion: ±0.1% accuracy, suitable for critical parameter monitoring of gas turbines (e.g., exhaust temperature, bearing vibration).
• Wide input compatibility: Supports thermocouples, RTDs, current/voltage signals, reducing the variety of spare parts.
• Industrial-grade anti-interference: 1500V isolation + EMI filtering, passing IEEE 472 surge tests.
• Plug-and-play maintenance: Modular design supports on-line replacement (requires system shutdown).
• Long-term reliability: Uses military-grade components with an MTBF of 200,000 hours.

Application Fields

Gas Turbine Control

• Combustion chamber temperature monitoring (Type K thermocouple).
• Signal conditioning for lubricating oil pressure transmitters (4-20mA).

Steam Turbine Protection

• Processing of bearing vibration sensors (velocity/acceleration signals).
• Monitoring of condenser vacuum (RTD).

Power Plant Automation Transformation

• Signal upgrading for older Mark I/Mark II systems.

Installation and Maintenance

Pre-installation Preparation

• Ensure the system is powered off and use an anti-static wristband.
• Check that backplane slots are free of oxidation and that module jumper settings match the sensor type.
• Prepare shielded twisted-pair cables (e.g., Belden 8761) for analog signal transmission.

Maintenance Recommendations

• Perform calibration checks every 12 months (using a Fluke 744 process calibrator).
• Regularly clean the module’s heat dissipation holes to prevent overheating due to dust accumulation.
• Record jumper positions when replacing modules to ensure consistent configuration of the new module.
