Compatible Replacement & Equivalent Models
Direct Drop-in Replacements
Direct substitutes share the same part number family and are physically and electrically interchangeable with no configuration changes required. Verify firmware version compatibility with your system controller before installation.
- WOODWARD 8440-1041 (surplus / refurbished tested units)
- WOODWARD 8440-1041A / 8440-1041B (suffix variants — confirm with Woodward revision history)
Functional Equivalents
Functional equivalents perform the same control role but may require parameter re-configuration, firmware update, or minor wiring adaptation. Suitable for planned maintenance windows.
- Other modules within the WOODWARD 8440-xxxx series with matching I/O count and protocol
- WOODWARD MicroNet or NetCon platform modules with equivalent channel mapping (requires engineering review)
Cross-Brand Alternatives
Cross-brand substitutes from other automation vendors may replicate the functional role but require full system integration engineering, updated HMI configuration, and re-commissioning. Recommended only for full system upgrades.
- Emerson Ovation control modules (equivalent I/O class)
- Honeywell TDC / Experion series control cards (with protocol bridge)
- ABB AC800M I/O modules (for greenfield replacement projects)
⚠ Note: Cross-brand alternatives are not plug-and-play. Always engage a qualified controls engineer before substitution.

Selection Guide
Answer these three questions to confirm the 8440-1041 is the right fit — or to identify the best equivalent:
- Is your existing system a Woodward governor or turbine control platform? If yes, the 8440-1041 is likely a direct fit. If no, a functional equivalent or cross-brand alternative may be required.
- What is the firmware revision of your current controller? Firmware mismatches between modules can cause communication faults. Konmask can help verify compatibility before shipment.
- Is this a like-for-like emergency replacement or a planned upgrade? Emergency replacements should prioritize direct drop-in units; planned upgrades may benefit from evaluating functional equivalents with improved specifications.

Replacement & Compatibility FAQ
Q: Can I use a WOODWARD 8440-1041 equivalent from another manufacturer to replace my existing module?
A: Functional equivalents from other brands can substitute the 8440-1041 in terms of control role, but they are not plug-and-play replacements. Protocol adaptation, wiring changes, and re-commissioning are typically required. Konmask recommends using a genuine or surplus-tested 8440-1041 for direct replacement to minimize downtime risk.
Q: Is the WOODWARD 8440-1041 compatible with all Woodward governor systems?
A: The 8440-1041 is compatible with specific Woodward control platforms. Compatibility depends on the system generation, backplane revision, and firmware version. Contact Konmask with your system model number for a definitive compatibility check before ordering.
Q: What is the difference between a substitute and an equivalent for the WOODWARD 8440-1041?
A: A substitute typically refers to a unit that can replace the 8440-1041 with minimal or no modification — usually another Woodward module from the same series. An equivalent may refer to a module from a different brand or series that performs the same function but requires engineering adaptation. Konmask can supply both and will advise on the correct approach for your application.
