Features:

  • Terminates up to sixteen RTD channels for one Honeywell LLMux unit.
  • Routes low-level resistance signals to a single I/O processor path.
  • Uses compression terminals in the documented CE execution.
The assembly terminates low-level resistance-temperature detector wiring for the Honeywell LLMux measurement subsystem.

RTD lead resistances are presented through the FTA to the LLMux electronics, which applies the configured excitation and calculates temperature from the measured resistance. The FTA itself provides termination and routing rather than performing control calculations.

Confirm RTD type, lead configuration, single-IOP execution, compression-terminal wiring and unit address. Shielding and cabinet routing must protect low-level signals from power-cable interference.

Availability is reviewed against the exact MU-TAMR03 51309218-125 order identity and requested supply condition; manufacturer lifecycle status: Discontinued / Obsolete by OEM.

  • A complete LLMux path combines the I/O processor, power adapter and field termination assembly. One unit serves channels 1-16; a second documented unit extends the arrangement to channels 17-32.
  • The assembly is used for plant temperature inputs where multiple low-level RTD circuits must be concentrated near the control-system cabinet while preserving their channel identity.
  • Requires exact sensor wiring, unit address and low-level shielding practices.
  • Routes RTD lead resistance through the FTA to LLMux electronics.
  • Supports up to 16 RTD channels per LLMux unit.
  • Excitation and resistance conversion occur within the LLMux processor.
  • Unit 0 serves channels 1–16; Unit 1 serves channels 17–32.
  • Uses compression terminals for low-level RTD field wiring.
  • Part-number identity must match the documented CE-designated hardware execution.
  • Terminates resistance-temperature detector wiring for the Honeywell LLMux subsystem.
  • Connects through a single IOP interface.
  • Applies to the documented CE LLmux installation arrangement.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does the LLMux RTD subsystem require Honeywell MU-TAMR03 51309218-125?
The assembly terminates low-level resistance-temperature detector wiring for the Honeywell LLMux measurement subsystem.
How does part number 51309218-125 distinguish Honeywell MU-TAMR03 hardware?
The manufacturer data specifies Part number as 51309218-125; the installed arrangement must match that exact value.
How are RTD resistances routed by Honeywell MU-TAMR03 51309218-125?
RTD lead resistances are presented through the FTA to the LLMux electronics, which applies the configured excitation and calculates temperature from the measured resistance. The FTA itself provides termination and routing rather than performing control calculations.
What lead and addressing checks apply to Honeywell MU-TAMR03 51309218-125?
Confirm RTD type, lead configuration, single-IOP execution, compression-terminal wiring and unit address. Shielding and cabinet routing must protect low-level signals from power-cable interference.
Why is Honeywell MU-TAMR03 51309218-125 now classified as phased out?
The page records Active / Available from OEM. Apter Power reviews the exact order identity and condition without presenting this as an OEM delivery promise.
Which channel map should accompany Honeywell MU-TAMR03 51309218-125 documentation?
Submit the complete nameplate, Channel allocation (Unit 0: channels 1-16; Unit 1: channels 17-32 in a two-unit arrangement), installed system evidence, condition, quantity and destination so the document and quotation match MU-TAMR03 51309218-125.
