Compatible Replacement & Equivalent Models
When the KJ4006X1-BC1 is unavailable or discontinued, the following models may serve as functional equivalents depending on your system configuration. Always verify compatibility with your DeltaV I/O card before substitution:
- KJ4006X1-BC2 – Revised revision of the same terminal block series; check fuse rating compatibility
- KJ4001X1-BA1 – Unfused 8-channel terminal block; suitable where external fusing is already in place
- KJ4006X1-BB1 – Earlier revision; functionally similar, verify connector pinout
- Third-party DeltaV-compatible terminal blocks – Available from certified automation parts suppliers; must match channel count, fuse spec, and connector type
Note: Konmask.com recommends using OEM parts wherever possible. Substitutions should be validated by a qualified DeltaV system integrator.

System Compatibility
The KJ4006X1-BC1 terminal block is designed for use within the Emerson DeltaV control system architecture. Confirmed compatible I/O module families include:
- DeltaV S-series I/O cards (analog input/output modules)
- DeltaV M-series subsystem I/O
- DeltaV SIS (Safety Instrumented System) — verify SIL rating requirements separately
Not compatible with: Fisher ROC, Ovation, or non-DeltaV Emerson platforms without engineering review.
Selection Guide
Use the following criteria to confirm the KJ4006X1-BC1 is the right terminal block for your application:
- Channel count: Do you need 8 field wiring termination points? ✔
- Fusing requirement: Is per-channel fuse protection required by your safety or design standard? ✔
- DeltaV platform: Are you running an Emerson DeltaV S- or M-series system? ✔
- Connector type: Confirm the mating I/O card connector matches KJ4006X1-BC1 pinout
- Fuse rating: Verify the fuse amperage matches your field device current draw
If any of the above criteria are not met, contact our technical team for an alternative recommendation.

Replacement & Compatibility FAQ
Q: Can I use KJ4006X1-BC1 with DeltaV SIS modules?
A: Potentially yes, but SIS applications require additional SIL validation. Contact us for documentation support.
Q: What fuse rating does the KJ4006X1-BC1 use?
A: Refer to the Emerson DeltaV hardware manual for your specific I/O card. Fuse specs vary by channel configuration.
Q: Is the 12P4720X062 the same as KJ4006X1-BC1?
A: Yes — 12P4720X062 is the Emerson internal reference/revision code for the KJ4006X1-BC1 assembly.
Q: Do you offer a warranty on this part?
A: Yes. New units carry the standard Emerson warranty. Refurbished units include a 90-day Konmask functional warranty.
Q: Can I return a part if it’s not compatible?
