Product Description
Woodward 8273-126 2301D Digital Load Sharing and Speed Control
Product Overview
- The Woodward 8273-126 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’s 2301D series, offering reliable control for diesel, gas, or dual-fuel engines in single or parallel operation. The 8273-126 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 8273-126 is similar to other 2301D models (e.g., 8273-1011 2301D) but may have specific configurations, such as different actuator compatibility or certifications. It is distinct from Woodward’s 2301E series (e.g., 8273-1011 2301E), 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).
