Functional Description

5501-432 is a Actuator Control Module developed by Woodward. The Module is specifically designed to handle two independent actuator channels. It operates with a current rating of 200mA. The module is capable of precise and responsive control, making it ideal for critical applications where accurate actuator positioning is crucial. In addition to its control capabilities, the Control Module incorporates comprehensive diagnostics and fault monitoring features. These features enable real-time monitoring of actuator health and performance, facilitating proactive maintenance and troubleshooting.


  • Each channel is responsible for controlling an integrating or proportional, hydromechanical or pneumatic actuator. Each actuator may be equipped with up to two position feedback devices.
  • There are various versions available, and the module part number indicates the maximum output current capability of the module. This module requires a MicroNet low-density discrete (gray) cable. Use a digital (black) cable instead.
  • The module provides valuable information about actuator status, fault codes, and alarm conditions, ensuring efficient operation and minimizing downtime.

Actuator Outputs

If an actuator output isn't working properly, check the following:

  • Check to ensure that the cable is shielded and that the shield is properly grounded.
  • Check the load resistance to make sure it is less than the specified limit.
  • Check to make sure the load wiring is isolated.
  • Examine the wiring for any loose connections on the terminal blocks, as well as any disconnected or misconnected cables.
  • Connect a resistor across the output and disconnect the field wiring.
  • Check the fuse on the MPU and Analog I/O module if the other output channels on the MPU and Analog I/O module are also not working. This fuse is visible and can be changed via the module's bottom. If the fuse has blown, repair the wiring and replace it with a fuse of the same type and rating.
  • Check the software configuration to ensure that the output is properly configured.


  • The modules are inserted into card guides in the control's chassis and connected to the motherboard.
  • Two screws, one at the top and one at the bottom of the front panel, hold the modules in place. There are also two handles at the top and bottom of the module that, when toggled (pushed outward), move the modules out just far enough for the boards to disengage the motherboard connectors.
