WOODWARD 9907-167

1. Product NameWoodward 9907 – 167 505E Digital Turbine Governor (Digital Turbine Control Module)
2. Product DescriptionThe Woodward 9907 – 167 is a core control module that belongs to the Woodward 505E series, mainly developed for the control of single – extraction and admission steam turbines. It serves as the control hub of industrial turbines, integrated with a 32 – bit high – performance microprocessor and a unique PID control structure.
   This module is capable of starting, stopping, controlling, and protecting steam turbines or turboexpanders, which can drive generators, compressors, pumps, and industrial fans. It can realize bumpless control mode switching when the equipment is in abnormal operation, so as to reduce the overshoot or undershoot of the production process.
   Encased in an industrial – grade rugged housing, it can be optionally equipped with a NEMA 4x protective shell to achieve an IP66 protection level, effectively preventing electrical components from being damaged by external factors. It is widely used in power generation, oil and gas, chemical industry, and marine fields, and has obtained CE, UL, and CUL certifications to ensure compliance with industry – related specifications.
