Product Description
Woodward 5501-1432 is a Dual Channel Actuator Control Module for Woodward MicroNet turbine control system. It is designed to drive electro-hydraulic and fuel actuators. This module provides two independent current outputs, configurable for proportional or integrating mode via software. It supplies ±245mA current to actuator coils for high-precision position control of fuel valves and steam control valves on steam and gas turbines. Built-in channel self-diagnosis, short-circuit and overload protection. On-board LEDs indicate channel operation and fault status. Rack-mount hot-pluggable card compatible with MicroNet control systems for turbine governor applications. This model is end-of-life from OEM and supplied only as spare parts for legacy power plant turbine units.
