Product Description
Product Overview
The Woodward 9907-018 is a 2301A Load Sharing and Speed Control designed to regulate the speed and load of diesel engines, gas engines, steam turbines, or gas turbines in industrial applications. This forward-acting, low-voltage control accepts a 4-20 mA or 1-5 VDC process demand signal to set the prime mover’s speed or load, supporting isochronous or droop operation. Housed in a sheet-metal chassis with a single printed circuit board, it is widely used in power generation, oil & gas, and marine systems for reliable load sharing and speed management.
