Compatible Replacement & Equivalent Models
When the KJ3243X1-BK1-SE4022 is unavailable or end-of-life, the following models may serve as functional replacements or equivalents. Always verify firmware compatibility and DeltaV version support before substitution.
- KJ3243X1-BK1 – Base variant without SE4022 firmware suffix; confirm DeltaV version compatibility
- Emerson KJ3222X1-BA1 – Alternative DeltaV Profibus DP card; verify I/O carrier slot compatibility
- Siemens CP 342-5 – Third-party Profibus DP master for S7-300; requires gateway or protocol converter for DeltaV integration
- Hilscher CIFX 50-DP – Universal Profibus DP master card; requires custom driver integration
- HMS Anybus X-gateway – Protocol bridge solution for cross-platform Profibus DP integration
Note: Third-party replacements require engineering validation. Konmask recommends using genuine Emerson parts for DeltaV systems to maintain system integrity and warranty.
Why Choose the Original Model
- Native DeltaV Integration: Plug-and-play with DeltaV Explorer; no custom driver development required
- Firmware-Validated: SE4022 suffix confirms a specific validated firmware revision for stability
- Emerson Support: Full lifecycle support, diagnostics, and remote monitoring via DeltaV system
- Reduced Commissioning Risk: Pre-tested with DeltaV I/O subsystem; minimizes integration risk in brownfield projects
- Long-Term Availability: Konmask maintains stock of legacy and current DeltaV I/O cards for MRO and capital projects

- Profibus Standard: IEC 61158 Type 3, EN 50170 Volume 2
- GSD File: Required for slave device configuration; available from device manufacturer
Selection Guide
Use the following criteria to confirm the KJ3243X1-BK1-SE4022 is the correct card for your application:
- Step 1 – Confirm DCS Platform: This card is exclusively for Emerson DeltaV systems. If your DCS is a different platform, a protocol gateway will be required.
- Step 2 – Verify Firmware Suffix: The SE4022 suffix denotes a specific firmware build. Cross-reference with your DeltaV system version to ensure compatibility.
- Step 3 – Count Profibus Slaves: Confirm your Profibus DP segment slave count does not exceed the card’s maximum (125 slaves/segment).
- Step 4 – Check Carrier Slot Availability: Ensure an available slot exists on your DeltaV I/O carrier before ordering.
- Step 5 – Assess Redundancy Requirements: For critical loops, evaluate whether a redundant Profibus DP card configuration is required.

Replacement & Compatibility FAQ
Q: Can I use KJ3243X1-BK1 (without SE4022) as a direct replacement?
A: Possibly, but the SE4022 suffix indicates a specific firmware revision. Confirm your DeltaV version supports the base variant before substitution.
Q: Is this card compatible with DeltaV v13 and v14?
A: Compatibility depends on the specific DeltaV release. Contact Emerson or Konmask with your DeltaV version for confirmation.
Q: Can this card interface with non-Emerson PLCs?
A: No. The KJ3243X1-BK1-SE4022 is designed exclusively for the DeltaV I/O subsystem and cannot be used standalone with third-party PLCs.
Q: Do you supply the GSD file for Profibus slave configuration?
A: GSD files are provided by the slave device manufacturer. Konmask can assist in locating the correct GSD file upon request.
Q: What is the difference between Profibus DP and Profibus PA?
A: Profibus DP is optimized for fast, cyclic data exchange with drives and discrete I/O. Profibus PA is used for process instrumentation in hazardous areas. This card supports Profibus DP only.
