• Utility Peaking Plants: Enables rapid response and precise load following for grid support

System Integration & Solutions

This controller integrates seamlessly with Woodward actuators, sensors, and complementary modules to form a complete engine control solution. It communicates via analog load sharing lines and can be configured for various engine types and generator configurations.

For comprehensive generator control systems, consider pairing with Woodward 9905-068 2301A for redundant control architectures, Woodward 8273-1011 2301D for expanded I/O requirements, or Woodward 9907-022 2301A for legacy system upgrades.

Common Questions & Answers

Q: Can the 8273-140 control both diesel and natural gas engines?
A: Yes, the 2301D series is compatible with both diesel and gas engines. Configuration parameters can be adjusted for fuel type, engine displacement, and actuator characteristics.

Q: How many generators can operate in parallel with this controller?
A: The 8273-140 supports unlimited parallel operation when properly configured with load sharing lines. Typical installations range from 2 to 16 gensets.

Q: Is this module compatible with electronic governors or only mechanical actuators?
A: The 8273-140 outputs analog control signals compatible with both electronic actuators (EGB, EPG series) and electro-hydraulic actuators. Verify actuator input requirements before installation.

Q: What is the difference between isochronous and droop mode?
A: Isochronous mode maintains fixed frequency regardless of load (ideal for isolated systems). Droop mode allows frequency to vary slightly with load, enabling stable parallel operation and natural load sharing.

Q: Does this unit require external programming or configuration tools?
A: Basic setup uses onboard potentiometers and DIP switches. Advanced tuning and diagnostics require Woodward's configuration software and interface cable (sold separately).
