Compatible Replacement & Equivalent Models
If the VE4050S2K1C0 is unavailable or you are evaluating alternatives, the following models are functionally equivalent or drop-in compatible within the DeltaV ecosystem:
- KJ4001X1-BE1 — OEM alternate part number for the same carrier module
- 12P0818X072 — Emerson internal revision/build code for this unit
- VE4001S2T2B2 — DeltaV Series 2 I/O carrier, compatible slot footprint
- KJ4001X1-BA1 / KJ4001X1-BC1 — Earlier revision carriers; verify firmware compatibility before substitution
- VE4050S2 (base series) — Confirm suffix codes match your I/O card type and channel count
Note: Always verify the I/O card type (AI, AO, DI, DO, HART) and channel density before selecting a replacement carrier. Contact Konmask.com for cross-reference assistance.

Selection Guide
Use the following criteria to confirm this is the correct carrier module for your application:
- Step 1 — Identify your I/O card type: Analog Input (AI), Analog Output (AO), Digital Input (DI), Digital Output (DO), or HART. The carrier suffix codes must match.
- Step 2 — Confirm Series: VE4050S2K1C0 is a Series 2 carrier. Series 1 carriers (VE4001S1…) are not interchangeable.
- Step 3 — Check channel count: Verify the number of I/O channels your application requires matches the paired I/O card.
- Step 4 — Verify revision suffix: K1C0 denotes a specific hardware revision. If your system requires a specific revision, confirm with Konmask.com before ordering.
- Step 5 — Redundancy requirements: If your loop requires redundant I/O, ensure the carrier and I/O card both support DeltaV redundancy.

Replacement & Compatibility FAQ
Q: Can I use KJ4001X1-BE1 as a direct replacement for VE4050S2K1C0?
A: Yes — KJ4001X1-BE1 and VE4050S2K1C0 are alternate part numbers for the same module. They are interchangeable.
Q: Is this carrier compatible with Series 1 DeltaV I/O cards?
A: No. Series 2 carriers (VE4050S2…) are not backward-compatible with Series 1 I/O cards. Verify your existing I/O card series before ordering.
Q: Can I replace this module while the DeltaV system is online?
A: DeltaV supports online I/O replacement (hot-swap) in most configurations. Consult your DeltaV system documentation and site safety procedures before performing live replacements.
Q: Do you supply the I/O card that mounts onto this carrier?
A: Yes. Konmask.com stocks a wide range of DeltaV I/O cards. Contact us with your I/O card part number for availability.
Q: What if my part number has a different suffix (e.g., K1C1 instead of K1C0)?
A: Suffix codes indicate hardware revisions. In most cases revisions are backward-compatible, but we recommend confirming with our technical team before substituting.
