Independent protection: The hardware level overspeed protection circuit is decoupled from the main control system, and can still trigger shutdown when the main control fails, improving the safety redundancy of the unit.
Comprehensive monitoring: Accurate collection of turbine speed through 6 speed inputs, real-time monitoring of acceleration/deceleration, and monitoring of the main control operation status through feedback signals, responding quickly in case of abnormalities.
Redundancy adaptation: Dual redundant Ethernet interfaces, compatible with Mark VIe fully redundant architecture, working in conjunction with TREA terminal boards to ensure reliable output of trip commands.
Strong diagnostic ability: LED real-time display module, communication and speed channel status, infrared serial port supports local diagnosis, can detect signal loss, module faults and other issues.
Hot swappable support: It can be replaced with power according to system specifications, reducing downtime for maintenance and improving system availability.
Industrial grade stability: multi-layer PCB and surface mount components, resistant to vibration and electromagnetic interference, suitable for harsh industrial environments.
Application scenarios
Gas/steam turbine: independent overspeed protection, main control abnormal backup trip, to prevent unit runaway and ensure safe start stop and operation.
Generator set: Monitor the speed of the generator, cooperate with the excitation system to achieve rapid shutdown in case of faults, and protect the stability of the power generation equipment and the power grid.
Petrochemical/metallurgical power equipment: overspeed protection for rotating machinery such as compressors and pump sets to avoid equipment damage and production accidents.
Distributed Control System (DCS) Expansion: As a signal interaction node between Mark VIe and on-site protection actuators, it is suitable for multi device centralized safety monitoring scenarios.
