Description
The Woodward 9907-1290 is a Digital Speed Controller Model II in the ProAct series, designed for speed control of high-performance engines and generator sets. This module utilizes an advanced 50MHz IOX processor, coupled with large-capacity flash memory (6MB) and NVRAM (8KB), supporting complex control algorithms to achieve extremely high-precision control of engine/turbine speeds.

Its control accuracy reaches ±0.1%, with extremely fast response times, allowing for millisecond-level adjustments. Through PID control, droop, and base-load control strategies, it can adapt to various load variations.

The 9907-1290 supports redundant design, configurable with dual power supplies and dual communication modules to improve system reliability and ensure high availability in critical applications. Communication interfaces include Modbus TCP/IP and HDLC diagnostic bus (2 Mbps), enabling integration with SCADA or higher-level systems for remote monitoring, parameter adjustment, and fault diagnosis.

The module's physical structure is rail-mounted and hot-swappable for easy maintenance. Its protection rating is available in IP20 (standard), with some versions offering even higher protection. It has a wide operating temperature range (–40°C to +70°C), suitable for industrial and extreme environments. The 9907-1290 is ideal for generator sets, marine main/auxiliary engines, compressor systems, or any application requiring high speed accuracy and reliability.
