WOODWARD 5466-409 HDDIO Module/CPU Processor Unit

    This HDDIO module handles discrete signal management in power generation systems. Designed for turbine control panels, it processes high-speed digital inputs from sensors while triggering output signals to actuators. The 5466-409’s galvanic isolation ensures stable operation in environments with electrical interference from heavy machinery.

    Commonly used in gas turbine monitoring systems where vibration sensors and emergency shutdown circuits require isolated signal paths. We’ve supplied these modules for retrofitting legacy Woodward governor systems in offshore oil platforms. They interface directly with turbine protection systems (TPS) through their 50kHz output channels.

    Our inventory includes related models like the WOODWARD 5466-258 position controller and 8521-0312 UG-10D speed controller. Engineers often pair this module with the 9907-164 control card for complete turbine management solutions.

    Personally, I found these modules particularly reliable in high-vibration environments – one customer in Singapore reported zero signal degradation after 18 months in a container terminal generator set. Their sealed construction handles dust and moisture better than older models.
