Product Description
Woodward 8250-828 Digital Control System
Product Overview
- The Woodward 8250-828 is a Digital Control System, part of Woodward’s advanced control solutions designed for precise regulation of industrial engines or turbines, particularly in applications such as power generation, marine propulsion, and industrial processes. This microprocessor-based control unit is likely associated with Woodward’s 723PLUS or similar digital control platforms, offering robust speed, load, and process control for diesel, gas, or dual-fuel engines, or small gas turbines. The 8250-828 provides integrated control, protection, and diagnostics, making it suitable for both new installations and retrofits. It features flexible communication options and is designed for reliable operation in demanding environments. The 8250-828 is distinct from Woodward’s 505D series (e.g., 8200-1300), Peak150 series (e.g., 8200-176), ProAct series (e.g., 8237-2595), and MicroNet systems (e.g., 5541-693), focusing on versatile engine or turbine control with customizable configurations.
