Compatible Replacement & Equivalent Models
When the 51304493-150 is unavailable or discontinued, the following models may serve as functional equivalents or replacements depending on your system revision. Always verify firmware and hardware compatibility before substitution:
- 51304493-100 – Earlier revision of the same PM Modem PCB series; verify revision compatibility
- 51304493-200 – Later revision; may offer enhanced communication stability
- 51304493-175 – Intermediate revision; confirm with Honeywell BOM documentation
- 51401288-100 – Alternative PM communication board used in select TDC 3000 configurations
- 51304485-100 – Related PM subsystem PCB; cross-reference with system schematic
Note: Revision suffixes (-100, -150, -200) indicate hardware revisions. Consult your system documentation or contact support@konmask.com for compatibility confirmation.

- Power generation and utilities automation
- Pulp & paper and continuous manufacturing processes
- Pharmaceutical batch and continuous process control
- Water treatment and municipal infrastructure automation
System Compatibility
- Primary Platform: Honeywell TDC 3000 DCS
- Subsystem: Process Manager (PM) — PM/APM/HPM variants (verify per system revision)
- Compatible Controllers: PM, APM (Advanced Process Manager), HPM (High-Performance Process Manager)
- Communication Bus: Local Control Network (LCN) / Universal Control Network (UCN)
- Not Compatible With: Experion PKS, PlantScape — different hardware architecture
Selection Guide
Use the following criteria to select the correct PM Modem PCB for your system:
- Step 1 – Identify your PM revision: Check the PM chassis label and existing board revision markings
- Step 2 – Match the suffix: The -150 suffix indicates a specific hardware revision; do not substitute with a different suffix without engineering review
- Step 3 – Verify firmware: Confirm that the replacement board’s firmware version is compatible with your PM controller firmware
- Step 4 – Check slot assignment: PM Modem PCBs occupy specific slots within the PM chassis — confirm slot mapping in your system documentation
- Step 5 – Source condition: For critical process applications, specify New OEM; for maintenance spares, Tested Refurbished is acceptable

Replacement & Compatibility FAQ
Q: Can I use 51304493-100 instead of 51304493-150?
A: Possibly, but the -100 is an earlier hardware revision. Functional compatibility depends on your PM firmware version. Contact us for a compatibility check before ordering.
Q: Is this board compatible with Honeywell Experion PKS?
A: No. The 51304493-150 is specific to the TDC 3000 PM platform. Experion PKS uses a different hardware architecture and is not compatible.
Q: Do you offer tested/refurbished units?
A: Yes. We offer New OEM, Tested Refurbished, and Exchange options. Specify your preference when ordering.
Q: What is the warranty on this part?
A: New OEM units carry the manufacturer’s standard warranty. Refurbished units carry a 12-month Konmask warranty covering functional defects.
Q: Can you provide a datasheet or wiring diagram?
A: Yes, available upon request for verified industrial buyers. Email support@konmask.com with your company details.
