FAQ

Q1: What is the Honeywell 51304477-100 (MU-TAMR02) used for?
It is a 16-channel LLMux RTD Field Termination Assembly for Honeywell TDC 3000 / Experion PKS DCS. It provides field wiring termination and multiplexing for RTD temperature sensors, routing the low-level resistance signals to the LLMux IOP .

Q2: How many channels does it have?
16 RTD input channels .

Q3: What RTD types are supported?
The module is designed for RTD sensors. While official specifications are not present in the search results, third-party sources indicate support for Pt100, Pt1000, Ni120, and Cu10 in 2-, 3-, or 4-wire configurations . Verify this against official Honeywell documentation before design-in.

Q4: Does it support thermocouples?
No. The MU-TAMR02 is an RTD-specific FTA. For thermocouple inputs, a different FTA (e.g., MU-TAMT12/MC-TAMT12) is required. One source incorrectly claims thermocouple support ; this is contradicted by the RTD-specific documentation .

Q5: What is the resolution?
8 mΩ per bit .

Q6: Does it support redundancy?
No. The 51304477-100 is a non-redundant FTA with a single IOP interface .

Q7: Is this FTA conformally coated?
No. The base -100 variant is not conformally coated. For conformal coating, a different variant (e.g., MC-TAMR02) would be required. Confirm exact variant availability with Honeywell.

Q8: Is this FTA CE compliant?
No. The base -100 variant is not CE compliant .

Q9: What are the dimensions and weight?
Conflicting sources: One cites 254 × 178 × 51 mm and 0.68 kg ; another cites 300 × 200 × 200 mm and 2 kg . Verify against official Honeywell documentation for your exact revision.

Q10: Is this a current or legacy product?
The TDC 3000 / Experion PKS is a legacy/mature platform. The 51304477-100 is primarily available as spare or refurbished stock. Confirm availability with Honeywell or an authorized distributor.

Q11: Where can I get technical documentation?
Official Honeywell documentation, or an authorized distributor, is the authoritative source for specifications and compatibility. Note that third-party listings contain conflicting data.
