Product Performance
Integrates multiple types of high-channel input and output interfaces, can process analog, digital and RTD temperature signals simultaneously, adapts to the multi-parameter collection and regulation needs of steam turbine control, and improves system integration compactness
High precision of analog signal processing, accuracy better than ±0.1% full scale in the full operating temperature range, can accurately capture subtle changes in key parameters of the steam turbine, ensuring the accuracy of regulation commands
Equipped with a 32-bit high-performance industrial processor, the digital response time is ≤0.5ms, which can quickly process control logic and respond to changes in on-site signals, improving the real-time performance and sensitivity of steam turbine control
High electrical isolation design between channels and between channels and backplane, combined with enhanced anti-electromagnetic interference circuit, can effectively resist strong electromagnetic radiation and surge impact in industrial sites, ensuring stable signal transmission and control logic operation
Equipped with complete full-link fault diagnosis and multiple protection functions, it can real-time monitor the module operation status, quickly alarm and take protective measures in case of failure, avoid fault expansion, and ensure the safety of the steam turbine unit
Wide operating temperature range of 0℃ – 65℃, industrial-grade rugged packaging design, can long-term stable operation in complex industrial sites with high temperature, high humidity and multiple interferences, with strong environmental adaptability
Deeply compatible with the GE Mark VIe series steam turbine control system, supporting online configuration debugging, parameter configuration and firmware upgrade, simplifying system integration and later maintenance processes
Supports redundant backup configuration, can form a redundant control unit with the same model module, further improving the reliability of the control system and meeting the uninterrupted operation needs of the steam turbine unit
High-reliability design, MTBF ≥3,500,000 hours, fully matching the rigorous control requirements for long-term stable operation of industrial steam turbines
