FAQ

Q1: What is the Honeywell 51309223-125 (MU-TAMT03) used for?
It is a 16-channel LLMux Thermocouple Field Termination Assembly for Honeywell TDC 3000 / Experion PKS DCS. It provides field wiring termination and multiplexing for thermocouple temperature sensors, with local cold junction compensation, routing signals to the LLMux IOP.

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

Q3: Does it use a local or remote CJR?
Local CJR integrated directly on the assembly. For a remote CJR version, the MU-TAMT13 is used.

Q4: Does it support RTD inputs?
No. The MU-TAMT03 is specifically for thermocouple (TC) inputs. For RTD applications, the companion MU-TAMR03 module is used.

Q5: What is the difference between MU-TAMT03 and MU-TAMT13?
The MU-TAMT03 has a local CJR. The MU-TAMT13 has a remote CJR interface, allowing the CJR to be located up to 50 meters from the FTA.

Q6: Does it support redundancy?
No. It uses a single IOP interface and does not support redundant configurations.

Q7: What IOP is required?
The MU-PLAM02 LLMux IOP, connected via the MU-TLPA02 Power Adapter.

Q8: What are the dimensions and weight?
Conflicting sources: Weight claims range from ~0.62 kg to 0.76 kg, 1.5 kg, and 3.0 kg (shipping). Dimensions range from 12.1 × 5 × 30.8 cm to 9.5 × 5.7 × 2.2 in. Verify against official Honeywell documentation.

Q9: Is this a current or legacy product?
The TDC 3000 / Experion PKS is a legacy/mature platform. The MU-TAMT03 is primarily available as spare or refurbished stock. Confirm availability with Honeywell or an authorized distributor.

Q10: Where can I get technical documentation?
Official Honeywell documentation, or an authorized distributor, is the authoritative source for specifications and compatibility.
