【英文介绍】

Woodward Powertrain ProTech 203 Overspeed trip device 9905-755 senses prime mover speed through three MPUs. Audible and visible alarm system.

Product 9905-755 is part of the ProTech 203 overspeed protection system family. The device family is modular in design, using three identical speed sensing units with a two-thirds voting configuration. This model has a 120 Vac/dc voltage input and is one of the power-on trip versions in the Woodward series.

To prevent system damage and breakdowns/failures, care should be taken to ensure that the 9905-755 overspeed protection is installed in the appropriate location. The Woodward Manual 85196 contains a complete list of environmental considerations, including an operating temperature range of -25 to +60 °C (-13 to +140 °F), protection from direct sunlight, water and condensation, and protection from vibration and potentially electromagnetic interference.

The Model 9905-755 has a speed sensing frequency range of 100 Hz to 32 kHz and a jump point frequency range of 250 Hz to 25 kHz. System features include MPU failure options, MPU failure timer, MPU failure indicator, and CPU failure indicator. Some errors are indicated by LED, some by alarm output, and some can optionally trigger both LED and alarm output.

The Woodward ProTech 203 Overspeed Protection System Manual 85196 details more system features, troubleshooting guidelines, environmental considerations, and more.
