Woodward 8237-1597 ProAct Digital Speed Control System
Product Overview
- The Woodward 8237-1597 is a ProAct Digital Speed Control System, designed for precise speed regulation of engines, particularly diesel or gas engines, in industrial applications such as power generation, marine propulsion, locomotives, and industrial processes. This microprocessor-based control unit integrates with Woodward__ ProAct actuators to provide accurate speed control, load sharing, and protection for reciprocating engines. The 8237-1597 is part of the ProAct series, known for its reliability, flexibility, and advanced diagnostics, making it suitable for both new installations and retrofits. Compared to other ProAct models like 8235-650, 8237-1245, or 8237-1247, the 8237-1597 may feature specific enhancements such as updated firmware, expanded communication capabilities, or certifications for hazardous areas, potentially tailored for advanced engine control requirements. It is distinct from Woodward__ 505D series (e.g., 8200-1300), Peak150 series (e.g., 8200-176), and MicroNet systems (e.g., 5541-693), focusing on engine speed control with a robust design for demanding environments.
