    FAQ

    Q1: What is the Honeywell 51305890-175 (MC-TAMT04) used for?
    It is a 16-channel LLMUX Thermocouple Field Termination Assembly for Honeywell TDC 3000 / Experion PKS DCS. It provides field wiring termination, signal conditioning, and cold junction compensation for thermocouple temperature sensors .

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

    Q3: Does it use a local or remote Cold Junction Reference (CJR)?
    The MC-TAMT04 features a local CJR integrated directly onto the assembly . Note: One source incorrectly claims no local CJR .

    Q4: Is it solid-state or relay-based?
    Solid-state — it eliminates mercury-wetted relays for improved durability and environmental safety .

    Q5: Is this FTA conformally coated and CE compliant?
    Yes. The MC-TAMT04 is conformally coated (CC) and CE compliant .

    Q6: What is the input range and resolution?
    Nominal input range is -20 to +100 mV (TC only), with 2 µV per bit resolution .

    Q7: What are the dimensions and weight?
    Dimensions: approx. 307.34 × 124.46 × 63.5 mm (12.1 × 4.9 × 2.5 in) . Weight: conflicting sources cite ~0.85 kg , 0.35 kg , and 1.0 kg . Verify against official Honeywell documentation.

    Q8: Is this a current or legacy product?
    The MC-TAMT04 is discontinued by Honeywell and is primarily available as surplus/spare stock . Confirm availability with Honeywell or an authorized distributor.

    Q9: 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 and inaccurate data (including claims of RS-485, relay outputs, and IP65 protection that contradict the FTA documentation).
