WOODWARD 9907-347｜ProTech 203 Overspeed Protection System｜

WOODWARD 9907-347｜ProTech 203 Overspeed Protection System｜illustration

Core functions:
Multi channel speed monitoring: Supports multiple input magnetic reluctance speed sensors (MPU) to achieve redundant monitoring and online testing.
Overspeed trip protection: When power is cut off, the trip relay is triggered to ensure safe shutdown of the prime mover in case of overspeed.
Hot swappable/modular design: supports hot swapping of modules, reducing downtime for maintenance.
Status display: Dual row LCD panel, real-time display of parameters such as speed, trip setting, fault status, etc.
Safety compliance: Supports high-level safety standards such as IEC 62508 SIL-3 and API 670, applicable to critical processes and energy systems.
