Compatible Replacement & Equivalent Models
When the VE4003S2B6 is unavailable or end-of-life, the following models are commonly evaluated as replacements or equivalents. Always verify firmware compatibility and carrier slot requirements before substitution.
- VE4003S2T2 – Functionally equivalent AI 16-CH HART variant; different terminal block style
- KJ3223X1-BB1 – Revised BOM revision of the same card family
- VE4001S2T2B2 – 8-CH AI HART card; use two units to replace one 16-CH card
- VE4005S2B2 – AI 16-CH non-HART variant; suitable where HART is not required
- Third-party DeltaV-compatible AI modules – Contact Konmask for validated alternatives
Note: Cross-referencing part numbers does not guarantee drop-in compatibility. Consult Emerson documentation or contact our engineers before ordering a replacement.

Replacement & Compatibility FAQ
Q: Can VE4003S2B6 replace KJ3223X1-BA1 directly?
A: Yes — VE4003S2B6 and KJ3223X1-BA1 are cross-reference part numbers for the same card. They are interchangeable.
Q: Is 12P2871X042 the same as VE4003S2B6?
A: Yes — 12P2871X042 is the Emerson internal manufacturing part number. All three numbers refer to the same physical module.
Q: Can I use this card in a non-DeltaV system?
A: No. This card is designed exclusively for the DeltaV I/O bus architecture and will not function in other DCS or PLC platforms.
Q: Does this card support HART 7?
A: Yes, with appropriate DeltaV firmware version. Confirm your DeltaV version supports HART 7 pass-through before installation.
Q: What is the difference between VE4003S2B6 and VE4003S2T2?
A: The primary difference is the terminal block connector style (B = barrier strip, T = spring-clamp terminal). Functionality and channel count are identical.
