The Woodward 2301E is a microprocessor-based load sharing and speed control for generators driven by diesel or gaseous engines. Building on the proven 2301A/2301D platform, the 2301E adds flexible software configuration via PC, four selectable operating modes, and Modbus RTU communication for DCS integration.
Key Features
Operating Modes
- Speed Control — multiple dynamics flexibility, works on pumps and compressors, remote 4–20 mA speed reference
- Isochronous Load Sharing — compatible with existing analog systems, soft load and unload capability
- Droop Base Load — adjustable load control via discrete raise/lower contacts
- Isochronous Base Load — constant load against utility bus, fixed or remote 4–20 mA load setting
