Compatible Replacement & Equivalent Models
When the 8C-PAIH51 is unavailable or under evaluation, the following models may serve as functional replacements or equivalents depending on system configuration:
- Honeywell 8C-PAIH01 (51454352-125) — Standard 8-ch AI, non-HART variant; verify HART requirement before substitution
- Honeywell 8C-TAIH51 — Redundant analog input variant; suitable for SIL-rated loops
- Honeywell CC-PAIH01 — C200/C300 compatible AI module; confirm IOTA carrier compatibility
- Honeywell 51304485-150 — Legacy TDC-3000 AI module; requires migration adapter for C300 use
- Yokogawa AAI141-S00 — Third-party equivalent for CENTUM VP; not directly interchangeable, requires engineering review
⚠ Always verify firmware version, IOTA carrier type, and system software revision before substituting modules. Contact Konmask technical support for cross-reference validation.

Replacement & Compatibility FAQ
Q: Can 8C-PAIH51 replace 8C-PAIH01 directly?
A: Yes, the 8C-PAIH51 is a superset of the 8C-PAIH01 with added HART capability. It is backward compatible in the same IOTA slot with no configuration change required.
Q: Is 8C-PAIH51 compatible with Experion PKS R310?
A: It is supported from R310 onward, but HART pass-through features require R400+. Verify your system revision before ordering.
Q: Can I use a third-party equivalent in a Honeywell C300 system?
A: Third-party modules are not natively supported by Experion PKS. Engineering-level integration work is required and may void Honeywell support agreements.
Q: What is the difference between 51454352-175 and other 51454352-xxx part numbers?
A: The suffix (-175, -125, etc.) denotes the feature set and firmware baseline. Always match the exact suffix to your system’s validated configuration list.
Q: Do you offer exchange or repair services?
A: Yes. Konmask offers board-level repair and exchange programs. Contact us with your failed unit’s serial number for a quote.
