Product Description

Part 8280-1009 is a 723PLUS Digital Control model (by Woodward Governor) suitable for use in a variety of applications, such as load-sharing systems and instances requiring torsional filtering. Two-speed inputs on this unit accommodate either proximity switches or magnetic pickups (MPUs). If proximity switches are to be used, speed signal frequencies must be below 100 Hz. A minimum frequency of 30 Hz must be maintained for steady-state speed control.


723PLUS Digital Controls are adjusted via either a Hand Held Programmer (part 9907-205) or Watch Window, a PC-based software. Part 8280-1009 has several compatible accessories in addition to the programmer/software. For generator load management, a Digital Synchronizer and Load Control (DSLC) can be connected, and if an application requires mechanical load sharing, a Rack Position Sensor can be used. Woodward 723PLUS Manual 02877 has more information on these accessories and more.


The 8280-1009 control must be mounted in a location that will maintain an operating temperature range of 40 to +70 °C (–40 to +158 °F). The unit must also be protected from water exposure (including condensation), vibration, and electromagnetic interference. Interference levels should not exceed levels defined in EN50082–2.


To suit a wider variety of applications, 723PLUS model 8280-1009 has analog and discrete inputs/outputs, both of which are configurable. In addition to these I/Os and the two-speed inputs, part 8280-1009 has multiple serial ports.
