Q1: What is the Honeywell 51401491-150 (MC-TAMT02) used for?
It is a 16-channel LLMux Thermocouple Field Termination Assembly for the Honeywell TDC 3000 / UCN DCS. It provides field wiring termination and multiplexing for thermocouple temperature sensors, routing signals to the LLMux IOP .
Q2: How many channels does it have?
16 thermocouple channels (indicated by the "comp (16)" designation in product listings) .
Q3: Is this FTA conformally coated?
Yes. The "MC-" prefix and "-150" suffix indicate conformal coating .
Q4: Is this FTA CE compliant?
No. The -150 variant is listed as the non-CE compliant version .
Q5: What terminal type does it use?
Compression terminals .
Q6: Is this product still current?
No. The MC-TAMT02 (51401491-150) is a legacy product that has been superseded by the LLMUX2 TC FTA (MC-TAMT04, 51305890-175), which is CE-compliant, conformally coated, and uses solid-state components instead of mercury relays . It is primarily available as spare or refurbished stock.
Q7: What IOP is required?
The MU-PLAM02 or MC-PLAM02 LLMux IOP, connected via the MU-TLPA02 Power Adapter (consistent with the LLMux FTA family).
Q8: 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 for this specific part number are extremely sparse and contain inaccuracies.
| Model | Description | When to Choose |
|---|---|---|
| 51401491-150 (MC-TAMT02) | LLMux TC FTA, 16-channel, compression terminals, conformally coated, non-CE | When conformal coating is required for legacy TDC 3000 / UCN installations (confirm availability; note superseded status) |
| 51401491-100 (MU-TAMT02) | LLMux TC FTA, 16-channel, compression terminals, uncoated, non-CE | When conformal coating is not necessary (note: some listings describe this as an IOP-side multiplexer board, not an FTA) |
| 51305890-175 (MC-TAMT04) | LLMUX2 TC FTA, 16-channel, solid-state switching, conformally coated, CE compliant (replacement for MC-TAMT02) | When a modern replacement with solid-state reliability and CE compliance is preferred |
| MU-PLAM02 / MC-PLAM02 | LLMux IOP | The required IOP for use with the MC-TAMT02 |
| MU-TLPA02 | Power Adapter | Required between the FTA and the LLMux IOP |
