Description
Product Description
The Woodward 8280-153 is a 723 Digital Control designed for generator, engine, and turbine control applications. This specific model uses a 90–150 VDC control power supply, distinguishing it from the low-voltage 723 versions. Woodward documentation identifies 8280-153 as part of the 723/QuadraLink control family and specifies the 90–150 VDC supply range.
The 723 provides configurable speed and load-control functions with discrete and analog I/O for integration with engine and generator systems. Depending on application configuration, the controller can accept magnetic-pickup speed signals, load-transducer inputs, KW reference signals, synchronizer inputs, and discrete control signals. The documented hardware also provides relay outputs for alarm and generator-breaker functions.

FAQ
Q: What is the Woodward 8280-153?
A: It is a high-voltage power-supply version of the Woodward 723 Digital Control.
Q: What voltage does the 8280-153 require?
A: The specified control supply range is 90–150 VDC. Woodward’s wiring documentation specifically identifies 8280-153 and 8280-317 for this supply range.
Q: What applications can use this controller?
A: The 723 family is used for engine and generator control applications, including speed, load, synchronization, and generator-control functions.
Q: Does it support analog load and reference signals?
A: Yes. The documented wiring provides 4–20 mA or 1–5 V inputs for KW load transducer and KW reference signals.
Q: Does the 723 support Modbus?
A: The documented 723 wiring identifies a J3 Modbus interface with RS232, RS422, or RS485 options.
Q: Can an application file from another 723 be loaded into this unit?
A: Compatibility must be verified by part number and revision. Woodward specifically recommends checking the control nameplate and matching the correct configuration file before installation.
