About the 9907-167

The 9907-167 unit is part of the Woodward 505E series of digital control devices. Manufactured by Woodward Inc., one of America's oldest independent turbine control system manufacturers, this series is specifically designed for industrial-sized steam turbines, small unit turbogenerators, and utility turboexpander models.

The 505E line, including the 9907-167, supports the single extraction and/or admission of steam turbines. It uses two actuators to drive the inlet steam valves, making the steam turbine operational.

Identified by the 9907-167 numerical designation, this model features a 32-bit microprocessor for precise turbine control. The unit's physical structure includes a series of printed circuit boards housed in a secure enclosure, allowing for reliable mounting within a control panel system.

Additionally, the 9907-167 can be equipped with an optional NEMA 4X grade protective casing. This casing provides effective protection against permanent damage or invasive particles and is suitable for both indoor and outdoor conditions. Without the protective frame, the unit operates within an ambient temperature range of -25 to 65°C. However, with the frame attached, it withstands temperatures up to 55°C.
