Compatible Replacement & Equivalent Models
When the AAI835-H00 is unavailable or end-of-life, the following models may serve as direct or functional replacements depending on your system revision and firmware version. Always verify compatibility with your FCS configuration before substitution.
- AAI835-S00 — Same series, alternate suffix; verify I/O channel count and terminal block compatibility
- AAI841-H00 / AAI841-S00 — Higher-density analog I/O variant; confirm nest slot compatibility
- AAI543-H00 — Analog input-only alternative for systems requiring dedicated AI modules
- AAI141-H00 — Legacy CS 3000 compatible analog input module; suitable for older FCS revisions
- Third-party equivalents: Consult Konmask engineering team for validated cross-reference to ABB, Honeywell, or Emerson analog I/O modules in hybrid migration projects

Replacement & Compatibility FAQ
Q: Can I replace AAI835-H00 with AAI841-H00 directly?
A: The AAI841-H00 has a higher channel density. It is physically compatible with the same I/O nest slot but requires re-configuration in CENTUM VP Builder. Confirm your FCS license supports the additional channels.
Q: Is the AAI835-H00 compatible with CENTUM CS 3000?
A: Yes, the AAI835-H00 is compatible with CENTUM CS 3000 R3 and later. Earlier revisions may require a firmware check.
Q: Do you supply refurbished AAI835-H00 units?
A: Yes. Refurbished units are available at reduced cost and are clearly identified. All refurbished units pass functional testing before shipment.
Q: What is the lead time for AAI835-H00?
A: In-stock units ship within 3–5 business days. Out-of-stock units typically have a 4–8 week lead time depending on sourcing channel.
Q: Can Konmask provide a cross-reference to other DCS brands?
A: Yes. Contact our engineering team with your system details for a validated cross-reference to ABB, Honeywell, Emerson, or Siemens analog I/O equivalents.
