Woodward 9905-660

Product Name:​ Woodward 2301A Series Load Sharing and Speed Control (9905/9907 Series)
Product Introduction:​ The 9905-660 is a member of the Woodward 2301A 9905/9907 series electronic load sharing and speed controls. These controls are used to govern the speed and load sharing functions of generators driven by diesel or gasoline engines, or steam or gas turbines. Specific sub-configuration parameters for 9905-660 are governed by series-level documentation.

Woodward 9905-659

Product Name:​ Woodward 2301A Series Load Sharing and Speed Control (9905/9907 Series)
Product Introduction:​ Based on series-level documentation, the 9905-659 belongs to the Woodward 2301A 9905/9907 series of electronic load sharing and speed controls. These controls govern the speed and load sharing of generators driven by diesel or gasoline engines, or steam or gas turbines. Verified public information specific to the exact configuration of 9905-659 (e.g., voltage class, actuator current range, forward/reverse acting, single/tandem actuator) is limited to series-level documentation.

Woodward 9905-658

Product Introduction:​ The 9905-658 is part of the widely adopted 2301A series of load sharing and speed control modules. Designed to govern the speed and load sharing functions of prime movers—such as diesel engines, gas engines, and turbines—this module provides precise isochronous or droop control, supporting both standalone and generator-parallel applications. The 9905-658 offers compatibility with dual-coil actuators and operates in a forward-acting configuration. It is field-configurable for various speed ranges and control dynamics.

Woodward 9905-656

Product Name:​ Woodward 9905-656 — Digital Microprocessor-Based Turbine Control / Current-to-Pressure Converter
Note:​ Publicly available documentation presents two distinct characterizations for 9905-656. The dominant characterization describes it as a digital microprocessor-based control device for turbines. Users should verify the exact configuration against the original procurement specification or Woodward's legacy database.

Woodward 9905-654

Product Name:​ Woodward 2301A Series Load Sharing and Speed Control (9905/9907 Series)
Product Introduction:​ The 9905-654 is a member of Woodward's 2301A family of electronic load sharing and speed controls. These controls are designed to govern the speed and share load for generators driven by diesel engines, gas engines, steam turbines, or gas turbines. The 2301A control is housed in a sheet-metal chassis and consists of a single printed circuit board; all potentiometers are accessible from the front of the chassis.

Woodward 6945-672

Product Name:​ Woodward Turbine Protection Monitoring System Component
Product Overview:​ This model is part of Woodward's Turbine Protection Monitoring System, contributing to comprehensive protection monitoring for steam turbines, gas turbines, and other prime movers. The system monitors speed conditions, vibration signals, and FSOV conditions to detect hazardous states and initiate protective trips.

Woodward 6945-671

Product Name:​ Woodward EHPC Electro-Hydraulic Actuator (6945 Series)
Product Overview:​ This model belongs to Woodward's EHPC (Electro-Hydraulic Position Controller) family, a linear integrated actuator typically used for steam turbine control valve or valve stand positioning. The actuator uses a low-pressure hydraulic oil source (80 to 250 psi / 552 to 1724 kPa) and employs a three-stage amplification to produce the required output shaft force. As a configured/custom actuator, the EHPC is designed and built for specific applications.

Woodward 6945-670

Product Name:​ Woodward Turbine Protection Monitoring System Component
Product Overview:​ This model is part of Woodward's Turbine Protection Monitoring System, contributing to comprehensive protection monitoring for steam turbines, gas turbines, and other prime movers. The system monitors speed conditions, vibration signals, and FSOV conditions to detect hazardous states and initiate protective trips.

Woodward 6945-669

Product Name:​ Woodward Turbine Protection Monitoring System Component
Product Overview:​ This model is part of Woodward's Turbine Protection Monitoring System, providing comprehensive protection monitoring for steam turbines, gas turbines, and other prime movers. The system monitors speed conditions, vibration signals, and FSOV (Fuel Shutoff Valve) conditions to detect hazardous states and initiate protective trips.
