Overview
The Woodward 5501-432 2CH Actuator Control Module is part of the NetCon controller family, engineered for high-precision actuator management in demanding industrial environments. It supports two independent actuator channels, each capable of delivering up to 200 mA (245 mA max) for responsive and accurate control.
Each channel can interface with one or two feedback devices, such as LVDTs or RVDTs, enabling closed-loop position control with high resolution. Moreover, the module includes watchdog hardware to monitor logic power and microcontroller activity, enhancing system reliability and fault tolerance. Its compact form factor and modular design make it ideal for integration into turbine control panels, compressor stations, and other automation systems.
Therefore, the 5501-432 is widely used in applications requiring precise actuator positioning, real-time feedback, and robust fault monitoring.
Technical Data
| Parameter | Specification |
|---|---|
| Model Number | 5501-432 |

Typical Applications
-
Turbine Control Systems: Manages fuel and steam valve positioning in gas and steam turbines.
-
Compressor Stations: Controls actuator-driven valves for pressure and flow regulation.
-
Engine Automation: Interfaces with throttle and governor actuators in industrial engines.
-
Process Control: Supports precise valve actuation in chemical and refining systems.
-
Retrofit Projects: Replaces legacy actuator modules with modern NetCon-compatible units.
For instance, in a steam turbine setup, the 5501-432 can drive two actuators controlling steam admission valves, using dual LVDTs for feedback to maintain precise load regulation. In addition, its watchdog logic ensures safe operation by detecting controller faults and initiating protective actions.
