Description：

The Woodward 701A digital speed controller offers superior speed control, with models specifically designed for low- to high-speed diesel, gasoline, or spark-fuel engines (one actuator drives two sets of linkages, controlling the gasoline fuel valve and diesel injection system separately).

The 701A controller uses a 16-bit microprocessor to implement all control functions. This controller features enhanced control dynamics, enabling smooth and stable operation while maintaining a rapid response to changes in engine speed and load.

Frequently asked questions

Q1: What is the WOODWARD 8280-192 used for?

A1: It is used for precise engine and turbine speed regulation in industrial control systems.

Q2: What type of engines is the 701A controller compatible with?

A2: The 8280-192 controller is suitable for medium-speed diesel engines, gas engines, and dual-fuel engines operating below 500 rpm. It supports both forward and reverse acting systems.

Q3: What power supply does the 8280-192 require?

A3: The 8280-192 low-voltage version operates with an input power supply range of 18–40 VDC, commonly using 24 VDC or 32 VDC systems.

Q4: What speed sensing methods are supported?

A4: The 8280-192 controller supports magnetic pickup sensors and proximity switch inputs for accurate engine speed monitoring and stable control performance.

Q5: Does the 701A support remote speed adjustment?

A5: Yes. The 8280-192 module supports remote speed setting through 4–20 mA or 1–5 VDC analog input signals for flexible remote engine management.

Product Applications

Industrial power generation equipment: Used to control diesel generator sets, providing smooth speed recovery during sudden load changes.

Marine propulsion systems: Used for speed regulation and control of main or auxiliary engines in ships.

Oil, gas, and petrochemical: Controls reciprocating engines that drive compressors or pumps.

Combined heat and power (CHP): Works with gas turbines or internal combustion engines to manage load distribution in multi-purpose power sources and complex electrical systems.
