Compatible Replacement & Equivalent Models
When the Honeywell 42622254-001 is discontinued, hard to source, or cost-prohibitive, the following models may serve as functional equivalents or drop-in replacements depending on your system configuration. Always verify electrical and mechanical compatibility before substitution.
- Honeywell 42622254-002 – Revised revision of the same combiner panel series; check firmware compatibility
- Honeywell 51304485-100 – Digital Output FTA (Field Termination Assembly) for Experion PKS; functionally equivalent in many TDC 3000 migration projects
- Honeywell 51304485-150 – Enhanced version with extended channel density
- Honeywell 51402573-150 – DO FTA compatible with HC900 and Experion series
- Third-party equivalents – Contact Konmask for cross-reference validation and sourcing support
Note: Replacement compatibility depends on DCS platform version, I/O bus type, and field wiring configuration. Consult your system documentation or contact our engineers.

- Digital output field termination in process automation panels
- Oil & gas upstream/downstream control systems
- Chemical and petrochemical plant automation
- Power generation and utilities control infrastructure
- Pharmaceutical manufacturing process control
- Pulp, paper, and continuous process industries
System Compatibility
- Honeywell TDC 3000 – LCN / UCN I/O subsystems
- Honeywell Experion PKS – C200, C300 controller I/O families
- Honeywell PlantScape – Legacy migration projects
- Honeywell HC900 – Hybrid controller I/O expansion (verify revision)
Always cross-reference the combiner panel revision with your DCS I/O card and FTA pairing requirements before ordering.
Selection Guide
Use the following criteria to determine whether the 42622254-001 is the right component for your project:
- Step 1 – Identify your DCS platform: Confirm whether your system is TDC 3000, Experion PKS, or a hybrid migration environment.
- Step 2 – Verify I/O card pairing: The combiner panel must match the corresponding digital output I/O card (e.g., 51304516-150 or equivalent).
- Step 3 – Check channel count: Confirm the number of digital output channels required per panel assembly.
- Step 4 – Assess field wiring type: Ensure terminal block and wiring gauge compatibility with your existing field cables.
- Step 5 – Evaluate replacement vs. original: If the original is unavailable, use the equivalent models listed above with engineering sign-off.
- Step 6 – Contact Konmask: Our technical team can validate your selection and provide sourcing options across new, refurbished, and tested stock.

Replacement & Compatibility FAQ
Q: Can I use a third-party replacement for the Honeywell 42622254-001?
A: Functionally equivalent third-party panels may exist, but OEM replacements are strongly recommended for safety-critical DCS environments. Contact us for validated alternatives.
Q: Is the 42622254-001 still in production?
A: Honeywell periodically revises or discontinues legacy DCS components. Konmask maintains stock of both current and legacy parts — contact us to confirm availability.
Q: What is the difference between a combiner panel and an FTA?
A: A Field Termination Assembly (FTA) is the broader category; a combiner panel specifically aggregates multiple digital output channels into a single wiring interface. The 42622254-001 functions as a DO combiner/FTA within the Honeywell I/O architecture.
Q: Can this panel be used with Experion PKS C300 controllers?
A: Compatibility depends on the specific I/O card and FTA pairing. Please provide your system BOM or I/O card model for confirmation.
Q: Do you offer warranty on this part?
A: Yes. All units come with a minimum 90-day functional warranty. Extended warranty options are available — contact us for details.
