Description
The Woodward 5501-1432 is a 2-channel Actuator Controller. In industrial systems, it uses electrical signals to control valves or positioning devices, and monitors valve action via feedback signals, enabling the regulation of industrial media such as airflow and liquid flow.
Applications
Thermal power plants: control turbine inlet valves, fuel flow, and generator output.
Hydropower plants: drive turbine guide vanes to regulate water flow and speed.
Chemical plants: control large pipeline valves to maintain pressure and flow balance.
Steel plants: operate blast furnace fans, furnace gas valves, and rolling mill hydraulics for gas and motion control.
Feedback and Fault Monitoring
Position feedback: Each channel supports up to two sensors (LVDT/RVDT) for high-precision closed-loop control.
Fail-safe protection: The module monitors excitation, feedback, and drive status in real time. If communication with the main CPU is lost, the red Fault LED stays on and all outputs are shut down for safety.
Self-test status: A flashing Fault LED indicates internal hardware failure (MCU or capacitors). The module typically requires full replacement.
