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
I/O
- 1 load sensor circuit
- 1 actuator driver (4–20 mA, 0–20 mA, 0–200 mA, or PWM)
- 1 MPU speed sensor
- 1 configurable analog output, 2 configurable analog inputs
- 8 discrete (switch) inputs, 4 discrete (relay driver) outputs
- Modbus RTU via RS-422
