WOODWARD 9905-211 Speed Control Module for Industrial Engines

Description

TheWoodward 9905-211is part of the701 series of digital speed controls, designed forreciprocating enginesin power generation, marine propulsion, and industrial automation. It uses a16-bit microprocessorto deliverfast, stable, and accurate speed controlacross a wide operating range. The unit is part of the2301A family, known for reliability and adaptability in demanding environments. The 9905-211 supportsPID control, start fuel limiting, and ramp generator functions, allowing operators to fine-tune engine behavior duringstartup and load transitions. It integrates withWoodward load sharing modules, enablingparallel operationof multiple generators or engines. The controller acceptsfrequency input signals from magnetic pickupsand provides a0-200 mA actuator output, compatible with Woodward actuators. It is housed in arugged panel-mounted enclosurewithLED indicatorsfor diagnostics and status monitoring.
