WOODWARD 9905-860 Analog Input Module – Multi-Channel Signal Acquisition | Woodward NetCon / MicroNet Series
Engineering Background: The WOODWARD 9905-860 is a dedicated analog input module engineered for Woodward’s turbine and industrial governor control platforms. Designed to interface directly with the NetCon and MicroNet control architectures, this module provides high-fidelity analog signal conditioning and digitization for critical process variables including speed, temperature, pressure, and load feedback in power generation and rotating machinery applications.
Product Positioning: As a core I/O component in Woodward’s distributed control ecosystem, the 9905-860 is the preferred choice for OEM system integrators, turbine OEMs, and MRO procurement teams requiring drop-in replacement modules with guaranteed compatibility. Konmask.com supplies this module from verified industrial surplus and authorized distribution channels, with full traceability documentation available on request.

Engineering Advantages
- Direct OEM Compatibility: Plug-and-play replacement for existing Woodward NetCon/MicroNet installations — no firmware modification required in most configurations.
- High Signal Integrity: Differential input architecture and hardware filtering minimize common-mode noise in high-EMI industrial environments.
- Redundancy Support: Compatible with Woodward’s redundant I/O architectures for critical turbine protection applications.
- Rapid Commissioning: Module auto-identification via backplane reduces configuration time during planned maintenance windows.
- Long Service Life: Industrial-grade components rated for continuous duty in harsh environments.
System Architecture & Signal Flow
The 9905-860 occupies a dedicated I/O slot within the Woodward control rack. Field wiring connects to the module’s terminal interface, where analog signals are conditioned, filtered, and converted to digital values by the onboard A/D converter. Digitized process values are transmitted over the Woodward proprietary backplane bus to the main processor module (e.g., NetCon CPU or MicroNet controller) for real-time control loop execution. The module supports both simplex and redundant bus configurations depending on the system build.

Technical FAQ
Q: Is the 9905-860 compatible with both NetCon and MicroNet platforms?
A: The 9905-860 is designed for Woodward’s governor control family. Compatibility depends on the specific rack generation and firmware version. Please provide your system model number for confirmation before ordering.
Q: Can this module be used as a direct replacement without reconfiguration?
A: In most cases, yes — the module uses backplane auto-identification. However, we recommend verifying the system’s I/O map and channel assignments with your Woodward system documentation or our technical team prior to installation.
Q: Do you provide a functional test report?
A: Yes. A functional test report is available upon request for all units. Please specify this requirement at the time of order.
Q: What is the warranty coverage?
A: All units carry a 30-day DOA (Dead on Arrival) warranty. Extended 90-day and 12-month warranty options are available — contact support for details.
Q: Can you supply multiple units for a plant-wide spares program?
A: Yes. We maintain stock and can source additional units for bulk spares programs. Contact us for volume pricing and availability.
