Woodward 9905-915

  • Product Name:​ Excitation Control Module (Woodward 9905 Series)
  • Product Introduction:​ The 9905-915 belongs to Woodward's 9905 series of control modules. Within the 9905 family it is configured as an excitation control module used in turbine and generator control systems.

Woodward 8915-489

Product Overview:​ The 8915-489 belongs to Woodward's DSLC product family of digital synchronizers and load control modules. Based on the DSLC series architecture (exemplified by the related 8915-948 model), it serves as the primary intelligence hub for paralleling single or multiple engine-driven generators with a main utility bus or with each other, integrating automatic phase matching, voltage calibration, breaker closing logic, and kW/kVAR load sharing into a single robust unit — eliminating the need for complex, multi-relay synchronizing panels. It is designed for microgrid management, combined heat and power plants, and critical emergency power networks.

Woodward 8915-055

Product Name:​ 505 Series Digital Governor (part number 8915-055)
Product Overview:​ The 8915-055 is a microprocessor-based digital governor controller from Woodward's 505 product family. While specific standalone details for 8915-055 require reference to official Woodward documentation, based on the 505 series architecture (exemplified by the closely related 8915-955 model), it is designed for speed control and protection of steam turbines and other rotating equipment.

Woodward 8915-046

Product Name:​ 505 Series Digital Governor for Steam Turbines (part number 8915-046)
Product Overview:​ The 8915-046 is a microprocessor-based digital governor controller from Woodward's 505 series, specifically designed for speed control and protection of steam turbines. It controls turbine speed by operating single or split-range actuators to drive steam inlet valves, providing precise speed and load control for industrial steam turbines, small grid turbo-generators, and turboexpanders.

Woodward 8904-922

Product Name:​ IC-922 Ignition Controller with ServLink
Product Overview:​ The IC-922 is a capacitive-discharge ignition system controller belonging to Woodward's IC-920/IC-922 family. It is designed for spark-ignited engines in gas compression, power generation, and other industrial applications. The IC-922 delivers "Big Strike" high energy for up to 20 ignition coils (24 optional), making it ideal for high-BMEP or misfire-prone engines that require very high ignition energy for stable combustion under lean-burn or other misfire-prone conditions.

Woodward 8904-786

Product Name:​ Actuator and Valve Combined Unit (part number 8904-786)
Product Overview:​ The 8904-786 belongs to the Woodward 8904 series of actuator and valve combined units for gas turbine fuel systems. The combined unit is delivered pre-matched and calibrated from the factory for direct installation into turbine fuel systems, integrating an electro-hydraulic actuator with a gas valve.

Woodward 8904-433

Product Name:​ Electronic Control Module / Actuator Driver (part number 8904-433)
Product Overview:​ The 8904-433 is a member of the Woodward 8904 control product family. Based on the 8904 series architecture, it functions as an electronic controller or actuator driver module for turbine/engine control systems, providing control interfacing for fuel valves or actuators.
