RTD FTA Identity
Sixteen Input Points
LLMux Architecture
Features:
- Honeywell table 12-1 directly maps MU-TAMR03 to 51309218-125.
- The manufacturer listings identify 16 RTD input points and compression terminals.
- The FTA is separate from the LLMux power adapter and I/O processor.
Honeywell HPM Planning table 12-1 identifies MU-TAMR03 as an LLMux RTD field termination assembly with part number 51309218-125. The manual's field assembly lists show 16 channels and compression terminal type for this model. Its CE parts table also maps 51309218-125 to the RTD FTA, while the coated MC-TAMR03 51309218-175 is a separate assembly. These are exact-model catalog facts; they do not establish the RTD sensor type, wiring resistance allowance, measurement accuracy or calibration for a particular installation.
The Honeywell LLMux diagram places the RTD FTA on the field side of a separate MU-TLPA02 power adapter and MU-PLAM02 IOP. Honeywell states that the LLMux component family does not interchange with RHMUX assemblies. For a planned exchange, identify the actual FTA label and revision, sensor wiring, channel assignments, terminal positions, adapter, IOP, cable and cabinet design. Follow plant isolation and current manufacturer procedures, then verify every affected temperature input against the actual connected RTDs. Do not infer thermocouple cold-junction specifications from the neighboring TAMT FTA or claim the termination assembly independently performs the IOP's signal processing.
The MU-TAMR03 51309218-125 Honeywell HPM 16-Point LLMux RTD FTA may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell MU-TAMR03 51309218-125 official technical documentation and product links.
This multi-page Honeywell technical document contains the exact model and its technical data. Apply the values to the supplied type number and verify its revision before installation.
Honeywell HPM Planning table 12-1 prints MU-TAMR03 and 51309218-125 on the same LLMux RTD FTA row. Another catalog table lists the part under CE-compliant non-coated FTAs. These manufacturer entries support the exact order identity without borrowing an MC model number. Verify the physical label and revision of the offered unit, since the historical catalog does not certify present stock condition.
The manufacturer FTA listings associate MU-TAMR03 with 16 RTD input points and compression terminals. This describes a field termination assembly rather than a standalone measuring processor. Actual sensor curves, input accuracy and configured channel behavior depend on the installed IOP and engineering configuration. Confirm the field wiring, RTD type, point assignments and approved system drawings before reconnecting any sensor.
Honeywell's LLMux diagram shows the RTD FTA connected via a separate power adapter to the LLMux IOP. The planning text says LLMux assemblies are compatible only with each other, not with RHMUX hardware. Record the adapter part, processor, cable and cabinet execution before ordering. After controlled replacement, inspect terminals and verify all affected temperature values and diagnostics through the complete installed assembly.
