Core Technical Characteristics & Performance Parameters
1. Professional Auxiliary Signal Processing Capacity
The module is equipped with multi-channel universal signal processing circuits, supporting adaptive processing of analog voltage, analog current and digital switching signals. It features built-in precise signal filtering and amplitude correction circuits, which can effectively eliminate high-frequency clutter and industrial electromagnetic interference signals. With stable signal output accuracy and low signal distortion rate, it ensures that the auxiliary operation data of the turbine is truly and completely transmitted to the main control system, meeting the high-stability signal transmission requirements of power generation equipment.
2. Stable Power Supply Adaptability & Low Power Consumption Design
Adopting wide-range DC voltage input design, the module can adapt to the unstable power supply environment of industrial power plants, with strong tolerance to voltage fluctuation and transient surge. The optimized low-power circuit structure effectively reduces operating power consumption and heat generation, supporting long-term fan-free continuous operation. It avoids equipment performance degradation and failure risks caused by long-term high-temperature operation, improving the overall operational stability of the control cabinet.
3. Reliable System Matching & Signal Linkage
Fully compatible with GE mainstream turbine control system architectures, the board can achieve seamless docking and signal linkage with various main control boards and acquisition modules. It supports synchronous signal transmission and data interaction, and can cooperate with the main control system to complete auxiliary equipment status monitoring, fault linkage alarm and operation parameter calibration. It features high system matching degree and strong compatibility, no need for additional program debugging during on-site installation and replacement, which greatly improves maintenance efficiency.
4. Comprehensive Electrical Protection & Anti-Interference Performance
The module adopts industrial-grade electromagnetic compatibility design, which can resist strong electromagnetic radiation and interference in complex power plant working environments. Built-in complete over-voltage, under-voltage, over-current and short-circuit protection circuits, it can quickly cut off the circuit for self-protection when abnormal electrical faults occur, preventing component burnout and system circuit failure. The high-isolation circuit design effectively isolates the interference between strong and weak current signals, ensuring the safety and stability of the entire control loop.
5. Excellent Harsh Environment Adaptability
Designed for heavy-duty industrial working conditions, the standard continuous operating temperature range is 0 ℃ to +65 ℃, and the extended temperature adaptation range covers -40 ℃ to +70 ℃, which can adapt to extreme temperature changes in power plant workshops and equipment cabins. The applicable ambient humidity is 5%–95% non-condensing, adapting to high-humidity and dusty industrial environments. The storage temperature ranges from -55 ℃ to +85 ℃, ensuring safe long-term storage and standby use of the module.
6. Compact Structure & Standardized Installation
With a compact and lightweight industrial circuit board structure, the module occupies small cabinet space and is convenient for integrated layout of turbine control cabinets. It supports standard embedded rack installation, with standardized wiring terminals and simple and fast installation and replacement procedures. The industrial-grade anti-corrosion and dust-proof circuit board coating improves the durability of the module and adapts to long-term industrial on-site operation conditions.
7. High Operational Stability & Maintainability
The module adopts mature and stable circuit design and industrial-grade electronic components, with low failure rate and long service life. It supports 24-hour uninterrupted S1 full-load continuous operation, fully matching the long-cycle operation mode of power generation units. It is equipped with intuitive circuit status detection points, which is convenient for on-site personnel to quickly detect faults and conduct daily maintenance, reducing equipment downtime and operation and maintenance costs.
