Selection Guide
Use this guide to confirm the MC-TAMR04 is the right module for your application:
- Step 1 — Identify your DCS platform: Confirm you are running Honeywell TDC 3000 (not Experion PKS or PlantScape).
- Step 2 — Verify input signal type: MC-TAMR04 is optimized for low-level signals (thermocouples, RTDs, mV). For 4–20 mA or 1–5 V signals, consider MC-TAIH04.
- Step 3 — Check channel count: MC-TAMR04 provides 4 channels. For 8-channel requirements, consult Konmask for alternative configurations.
- Step 4 — Confirm part number: Cross-reference 51305907-175 against your existing module label and system BOM.
- Step 5 — Contact Konmask: Our engineers can validate compatibility and provide a sourcing quote within 24 hours.

Replacement & Compatibility FAQ
Q: Can the MC-TAMR04 replace the 51305907-175 directly?
A: Yes — MC-TAMR04 and 51305907-175 refer to the same module. The part number and reference number are used interchangeably by Honeywell.
Q: Is the MC-TAMR04 compatible with Honeywell Experion PKS?
A: No. The MC-TAMR04 is designed for TDC 3000 architecture. Experion PKS uses a different I/O family (Series C). An adapter or migration module may be required.
Q: What is the difference between MC-TAMR04 and MC-TAIH04?
A: MC-TAMR04 handles low-level signals (thermocouples, RTDs, mV); MC-TAIH04 handles high-level analog inputs (4–20 mA, 1–5 V). Select based on your field device output type.
Q: Can I use a third-party replacement module?
A: Third-party alternatives exist, but OEM compatibility, firmware handshake, and diagnostic support must be verified. Konmask can advise on vetted alternatives.
Q: How long does delivery take?
A: In-stock units typically ship within 1–3 business days. Lead time for sourced units is 5–15 business days depending on availability. Contact us for current stock status.
