Q1: What is the Honeywell 51204168-100 (MU-TAIH62) used for?
It is a 16-channel High-Level Analog Input / Smart Transmitter Interface Field Termination Assembly for the Honeywell TDC 3000 / Experion PKS DCS. It provides field wiring termination, signal conditioning, and routing between field transmitters and DCS I/O processing channels .
Q2: How many channels does it have?
16 analog input channels .
Q3: Does it support HART communication?
Yes. It supports Smart Transmitter Interface (STI) functionality, enabling HART digital communication pass-through when paired with a compatible STI IOP (e.g., MU-PSTX01/02/03) .
Q4: What is the difference between MU-TAIH62 and MU-TAIH23?
Both are Enhanced Power HLAI FTAs, but the MU-TAIH23 must not be used for Smart Transmitter applications, while the MU-TAIH62 can be used for Smart Transmitter device applications .
Q5: What input signal types are supported?
4–20 mA current loop, 1–5 VDC, or 0–10 VDC voltage input .
Q6: What is the isolation rating?
250 VAC between safe-side and hazardous-side circuits .
Q7: What is the power consumption?
Maximum 1.28 A at 24 VDC, with power dissipation of 25.0 W when all inputs are at 20 mA .
Q8: What are the dimensions and weight?
Conflicting sources: One cites ~0.56 kg ; others cite 2.0 kg . Dimensions are also inconsistent . Verify against official Honeywell documentation for your exact revision.
Q9: Is this a current or legacy product?
The TDC 3000 / Experion PKS is a legacy/mature platform. The MU-TAIH62 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.
| Model | Description | When to Choose |
|---|---|---|
