Compatible Replacement & Equivalent Models
When sourcing a replacement for the 51304439-100 / MU-TDIA12, the following models may serve as functional equivalents or upgrades depending on your system revision and firmware compatibility:
- 51304439-150 — Revised revision of the same MU-TDIA12 series; verify firmware compatibility
- 51304439-200 — Higher-revision variant; confirm backplane slot compatibility
- MU-TDID12 — Digital Input module with extended diagnostics; pin-compatible in most TPS cabinets
- 51401544-100 — Alternative DI board used in TDC 3000 High-Performance Process Manager (HPPM)
- CC-TDIB01 — Experion PKS series digital input; requires migration adapter for TPS backplanes
Always verify hardware revision, firmware version, and backplane compatibility before substitution. Contact Konmask for pre-sales compatibility verification.

Selection Guide
Use the following criteria to confirm the correct digital input board for your system:
- Step 1 — Identify your DCS platform: TDC 3000 HPPM / BPM / TPS cabinet type
- Step 2 — Check backplane slot type: Confirm MU-series slot vs. CC-series slot
- Step 3 — Verify channel count: MU-TDIA12 supports 12-channel discrete input configuration
- Step 4 — Confirm voltage range: Match field device signal voltage to module input spec
- Step 5 — Review firmware revision: Ensure controller firmware supports the board revision (Rev 100 / 150 / 200)
- Step 6 — Contact Konmask: Provide your cabinet model and existing part number for final confirmation

Replacement & Compatibility FAQ
Q: Can 51304439-150 directly replace 51304439-100?
A: In most TPS installations, yes — the Rev 150 is a form-fit-function revision. However, confirm with your system integrator if running legacy TDC 3000 firmware below R500.
Q: Is MU-TDIA12 compatible with Experion PKS?
A: Not natively. Experion PKS uses CC-series I/O. A migration interface module is required. Contact us for migration kit options.
Q: Do you supply tested/refurbished units?
A: Yes. All refurbished units undergo full functional testing. Condition is clearly stated on each listing. New surplus units are also available.
Q: What warranty do you offer?
A: 90-day warranty on all units. Extended warranty available upon request.
Q: Can you source other Honeywell TDC 3000 / TPS parts?
A: Yes — Konmask specializes in legacy DCS components. Submit your full BOM for a consolidated quote.
