Woodward 8273-1011 2301D Digital Load Sharing and Speed Control
Product Overview
- The Woodward 8273-1011 is a 2301D 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__ 2301D series, offering reliable control for diesel, gas, or dual-fuel engines in single or parallel operation. The 8273-1011 provides integrated speed control, load sharing, and protection, with a user-friendly interface for configuration and monitoring. It is suitable for both new installations and retrofits, featuring robust communication options and a compact design for reliable operation in demanding environments. The 8273-1011 is distinct from Woodward__ 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 load sharing capabilities.
