Product Description
Woodward 8273-1011 2301E Digital Load Sharing and Speed Control
Product Overview
- The Woodward 8273-1011 is a 2301E Digital Load Sharing and Speed Control, designed for precise speed regulation and load sharing of engines in industrial applications such as power generation, marine propulsion, and industrial processes. This microprocessor-based control unit is part of Woodward’s 2301E series, an enhanced version of the 2301D series, offering advanced control for diesel, gas, or dual-fuel engines in single or parallel operation. The 2301E provides improved communication capabilities, enhanced diagnostics, and greater flexibility compared to the 2301D (e.g., 8273-1011 2301D). The 8273-1011 integrates speed control, load sharing, and protection with a user-friendly interface for configuration and monitoring, making it suitable for both new installations and retrofits. It is distinct from Woodward’s 505D series (e.g., 8200-1300), Peak150 series (e.g., 8200-176), ProAct series (e.g., 8237-2595), 723PLUS series (e.g., 8270-1013), and MicroNet systems (e.g., 5541-693), focusing on cost-effective engine control with advanced load sharing and communication features.
