Compatible Replacement & Equivalent Models
When the KJ4001X2-BE1 is unavailable or end-of-life, the following models may serve as functional equivalents or drop-in replacements depending on your DeltaV system revision. Always verify firmware and hardware compatibility before substitution.
- KJ4001X1-BE1 — Earlier revision carrier; functionally similar, verify shield bar compatibility
- KJ4001X2-BA1 / 12P0818X062 — Carrier without shield bar; suitable where EMC shielding is handled externally
- KJ4002X1-BE1 — Extended I/O carrier for higher channel-count configurations
- 12P0818X072 — OEM alternate part number; identical unit, different procurement source labeling
- Third-party DeltaV-compatible carriers — Contact Konmask for cross-reference validation
Note: Konmask.com provides cross-reference advisory services. Final compatibility must be confirmed against your DeltaV system version and I/O card type.

Replacement & Compatibility FAQ
Q: Is KJ4001X2-BE1 the same as 12P0818X072?
A: Yes. These are dual part numbers for the identical Emerson DeltaV I/O Carrier with Shield Bar — KJ4001X2-BE1 is the catalog number and 12P0818X072 is the OEM/manufacturing part number.
Q: Can I use KJ4001X2-BE1 without the shield bar connected?
A: Yes. The shield bar is a passive grounding component. The carrier functions normally if the shield bar is not connected, though EMC performance may be reduced.
Q: Is this carrier compatible with DeltaV SIS I/O cards?
A: The KJ4001X2-BE1 is designed for standard DeltaV I/O. SIS (Safety Instrumented System) applications require dedicated SIS-rated carriers. Contact us for SIS-compatible alternatives.
Q: What is the difference between KJ4001X2-BE1 and KJ4001X2-BA1?
A: The BE1 variant includes an integrated Shield Bar for field cable EMC grounding. The BA1 variant does not include the shield bar and is suited for installations where shielding is managed at the marshalling cabinet level.
Q: Do you offer volume discounts for project quantities?
A: Yes. Contact support@konmask.com with your project BOM for a tailored quotation.
