Compatible Replacement & Equivalent Models
When the KJ3242X1-BK1 is unavailable or end-of-life, the following models may serve as functional equivalents or drop-in replacements depending on your DeltaV system revision:
- KJ3242X1-BA1 — Earlier hardware revision; functionally equivalent in most DeltaV configurations
- KJ3242X1-BC1 — Later revision with enhanced diagnostics; backward compatible
- KJ3242X1-BD1 — Current production revision; recommended upgrade path
- EMERSON VE3006 — Alternative Fieldbus H1 card for specific DeltaV subsystem generations
- Third-party FF-H1 cards — Pepperl+Fuchs, Softing, or Turck FF-H1 interface modules may be considered for non-DeltaV systems; verify compatibility before use
⚠ Always verify firmware version and DeltaV system revision compatibility before substituting. Contact Konmask.com for pre-sales compatibility verification.

Selection Guide
Use the following criteria to determine whether the KJ3242X1-BK1 is the right card for your application:
- Step 1 — Confirm DCS Platform: This card is exclusively for Emerson DeltaV systems. If your DCS is ABB, Honeywell, or Yokogawa, select a platform-specific FF-H1 card.
- Step 2 — Check Hardware Revision: Identify your existing carrier/subsystem generation. BK1 revision is compatible with mid-generation DeltaV I/O subsystems.
- Step 3 — Count H1 Segments Required: Each KJ3242X1-BK1 supports one FF-H1 segment. Plan card quantity based on total segment count.
- Step 4 — Verify Firmware: Ensure DeltaV controller firmware supports the BK1 hardware revision. Upgrade firmware if necessary before installation.
- Step 5 — Consider Upgrade Path: If long-term support is a priority, evaluate the BD1 revision as a forward-compatible alternative.

Replacement & Compatibility FAQ
Q: Can I use KJ3242X1-BD1 as a direct replacement for KJ3242X1-BK1?
A: In most DeltaV configurations, yes. The BD1 is a later hardware revision with enhanced diagnostics and is backward compatible. Verify with your DeltaV system release notes.
Q: Is this card compatible with PROFIBUS or HART?
A: No. The KJ3242X1-BK1 is specifically designed for Foundation Fieldbus H1 (FF-H1) protocol only. Separate cards are required for PROFIBUS DP or HART multiplexing.
Q: Can I use this card in a non-Emerson DCS?
A: This card is designed exclusively for the Emerson DeltaV I/O subsystem and is not compatible with third-party DCS platforms.
Q: What is the difference between KJ3242X1-BK1 and KJ3242X1-BA1?
A: The BK1 is a later hardware revision of the BA1. Both are functionally equivalent for standard FF-H1 communication, but the BK1 may include minor hardware improvements. Check Emerson’s revision history for details.
Q: Do you provide a test report or certificate of conformance?
A: Yes. Certificates of conformance and inspection reports are available upon request for all orders.
