The Original Woodward 8237-1006 Speed Governor Spare is a digital speed control module from Woodward, providing speed and load control for prime movers — with both located sources pointing to gas engines and spark-ignition gas engine applications rather than turbines. One source describes it as a 505-series digital governor base unit: a standalone panel-mount digital speed and load controller with integrated 4–20 mA I/O and built-in overspeed protection logic ; another identifies it as the ProAct 737 digital speed control module for natural gas compression, power generation and mechanical drive duty. Both place it as a digital governor for gas-engine prime movers.

Original Woodward 8237-1006 Speed Governor Spare is the speed control brain of a gas-engine prime mover: it regulates speed and load against setpoints, drives the actuator for fuel/air control, and uses its overspeed protection logic to guard the machine during transients . Whether serviced as a 505-family base unit or the ProAct 737 module, it suits natural gas compression, generator sets and mechanical-drive applications where a digital governor must hold stable speed under changing load.
