Core Features
Independent main protection: The main overspeed protection logic is independent of the main controller, with redundant acquisition of 4-channel speed signals and triple voting to output tripping instructions, reducing the risk of protection failure caused by main controller failure.
Multi signal monitoring: Integrated with 8 flame sensor inputs, real-time monitoring of combustion status, combined with speed protection to achieve all-round unit safety protection.
Redundant communication: Dual redundant Ethernet interfaces are connected to the Mark VIe IONET network to ensure stable transmission of protection signals and control commands, and are compatible with single/dual redundant architectures.
Convenient maintenance: Supports hot swapping, automatic refactoring function simplifies configuration updates, LED displays real-time operating status, and fault information can be uploaded to the upper software for quick troubleshooting.
Wide temperature adaptation: operating temperature range of -40 ℃ to+70 ℃, suitable for harsh industrial environments such as power generation and petrochemicals, ensuring long-term stable operation.
Application scenarios
Gas/Steam Turbine: As the main protection core, it executes emergency trip logic such as overspeed and shutdown, and is suitable for combined cycle power plants and self owned power plants.
Petrochemical industry: used for safety protection of compressors and gas turbines to prevent equipment damage caused by overspeed and abnormal combustion.
Ship propulsion system: adapted to the main protection requirements of ship gas turbines, ensuring navigation safety.
High safety level industrial scenarios: meet hazardous site certification and are suitable for projects with strict requirements for equipment safety.
