Description
Product Description
The Woodward 9907-247 is the low-voltage version of the 828 Digital Control, designed for configurable engine, turbine, generator, marine, and industrial control applications. The controller supports two speed inputs for magnetic pickups or proximity switches, four analog inputs, three analog outputs, eight discrete inputs, and three discrete outputs. Its programmable I/O allows the same hardware to be adapted to different control strategies, including load-sharing applications. The 9907-247 operates from an 18–40 VDC supply, with 24 or 32 VDC nominal operation and approximately 40 W nominal power consumption. Woodward documentation identifies the 9907-247 specifically as the low-voltage 828 Digital Control model.
