WOODWARD 8256-016 Electric Speed Control Module

Series: It belongs to the EPG (Electrically Powered Governor) series.

Power Supply Voltage: 24V DC power supply.

Engine Types: Suitable for gasoline engines, diesel engines, and gas engines.

Maximum Wire Length: For 14 AWG wire, the maximum length is 11 meters; for 12 AWG wire, the maximum length is 23 meters.

Switch Rating: For model 1724, the switch rating is 10A.

Dimensions and Weight: The weight is approximately 26.30 pounds (about 11.93 kilograms).

Control Modes: It can realize single-phase synchronization or droop control, and flexibly adjust the engine's operation mode according to actual needs.

Signal Input: It can receive computer control signals, supporting 4-20mA or 1-5Vdc signal input, which facilitates integration with various control systems to achieve precise setting of equipment speed or load.

Working Modes: It has two working modes: isochronous regulation and droop regulation. Isochronous regulation is mainly used for constant speed control, applicable to scenarios where a single unit is running or multiple prime movers work together in an independent power grid; droop regulation provides more control flexibility.

Integration Capability: It can work in coordination with a series of Woodward's equipment, such as automatic power transmitters, input/output controllers, generator load controllers, etc., to achieve more comprehensive system control and improve the performance and reliability of the entire system.

Additional Functions: In addition to the basic speed or load control functions, it also has functions such as synchronization or deceleration control, high and low speed adjustment, and start-up fuel limit override, further enhancing its application capability under different working conditions.

Durability: Each component of the module has undergone anti-corrosion treatment, which can resist corrosion in harsh industrial environments and ensure long-term stable operation. Its operating temperature range is -40°C to 93°C, and it meets the vibration and shock standards of the U.S. military standard MIL-STD-810C, with strong anti-vibration and anti-shock capabilities.

Speed Sensing: Cooperating with the magnetic pickup unit, the magnetic pickup unit is responsible for sensing the engine speed and transmitting the speed signal to the speed control unit.

Signal Processing: The speed control unit receives the signal from the magnetic pickup unit, compares it with the preset speed value, and calculates the amount of adjustment needed.

Execution of Adjustment: According to the signal from the speed control unit, the 8256-016 actuator module adjusts the position of the engine's fuel control link, changes the fuel supply, thereby achieving precise control of the engine speed and stabilizing it at the preset speed value.

Power Generation Field: In diesel generator sets and gas generator sets, it is used to precisely control the engine speed to ensure that the generator outputs stable voltage and frequency, meeting the needs of power supply.

Industrial Drive Field: Such as pump drive, compressor drive, etc., it can precisely control the engine speed according to the requirements of the process flow to provide stable power output and ensure the continuity and stability of industrial production.

Marine Power Field: It is used for controlling marine diesel engines or gas engines, ensuring that the ship can accurately adjust the engine speed according to different working conditions such as acceleration, deceleration, and cruising, improving the ship's power performance and fuel economy.
