Replacement & Compatibility FAQ
Q: Can the 51304260-300 replace the 51304260-400 directly?
A: In most TDC 3000 installations, yes. The -300 and -400 revisions share the same hardware footprint and backplane pinout. Verify firmware compatibility with your DCS engineer before swapping in a live system.
Q: Is this module compatible with Experion PKS R500?
A: The 51304260-400 is primarily designed for TDC 3000 and PlantScape. For Experion PKS R500 and later, Honeywell recommends the CC-PAIX01 series. Contact us for migration guidance.
Q: Do you supply refurbished units?
A: Yes. All refurbished units are cleaned, inspected, and functionally tested. Condition is clearly stated on each listing. New surplus units are also available.
Q: What FTA is required for this module?
A: The matching FTA depends on your signal type and wiring configuration. Common pairings include the 51304453-150 and 51304453-175 FTAs. Contact Konmask.com with your loop drawing for confirmation.
Q: Can I get a datasheet or wiring diagram?
A: Yes — email support@konmask.com with your part number and we will provide available documentation.
