Woodward 2301D Rev G/E Digital Load Sharing & Speed Controller

Woodward 2301D Rev G/E is a microprocessor-based digital governor controller, designed for prime mover speed regulation and generator paralleling load sharing. It receives signals from magnetic pickup sensors and outputs drive signals to fuel actuators to stabilize engine operating speed.

This revision G/E supports isochronous and droop control modes, flexible remote speed setting and programmable load sharing logic. It can be configured via Watch Window software through RS232 port, widely used as spare parts for diesel and gas generator set control cabinet maintenance projects.
