Description
The Woodward 5464-414 is a high-density 8-Channel Analog Input Module engineered for the Woodward MicroNet and MicroNet Plus digital control platforms. It is designed to acquire precision process signals from field instrumentation—such as pressure transmitters, temperature sensors, and flow meters—and convert them into high-resolution digital data streams for real-time turbine governing and plant control calculations.

Engineering & Integration Guidance
When installing or replacing the 5464-414 module within a MicroNet chassis, observe the following parameters:
- Signal Mode Configuration: Input ranges (such as switching between 4–20 mA and voltage modes) are configured directly via software parameters within Woodward’s Graphical Application Program (GAP) environment without requiring physical jumper changes.
- Rack Power Safety: Completely de-energize the main rack 24 VDC power supply feed before inserting or extracting the module to prevent electrical arcing, backplane bus faults, or connector damage.
- Ground Loop Prevention: The module features robust channel-to-channel and channel-to-system galvanic isolation. Ensure proper shield grounding of field wiring to the cabinet ground bus to block external electromagnetic interference (EMI).
Frequently Asked Questions
What system architecture utilizes the Woodward 5464-414?
This module is built specifically for Woodward MicroNet and MicroNet Plus digital control racks deployed in critical gas turbine, steam turbine, compressor, and generator management systems.
Can this module be hot-swapped?
No. Standard MicroNet Simplex and standard rack maintenance protocols require a complete system power-down of the backplane slot before removing or installing internal input modules.
How does the module handle different sensor types?
The 8 independent channels accept multiple signal formats (voltage or current loops), which are digitized at high speeds and routed directly to the primary CPU for closed-loop governor control.
