Q1: What is the Honeywell 51204168-150 (MC-TAIH62) used for?
It is a 16-channel High-Level Analog Input / Smart Transmitter Interface Field Termination Assembly (FTA) for the Honeywell TDC 3000 / Experion PKS DCS. It provides field wiring termination, signal routing, and Enhanced Power with current limiting between field transmitters and DCS I/O processing channels .
Q2: How many channels does it have?
16 channels .
Q3: What is the difference between 51204168-100 (MU-TAIH62) and 51204168-150 (MC-TAIH62)?
The -100 (MU-TAIH62) is the non-coated variant. The -150 (MC-TAIH62) is the conformally coated variant for harsh environments. Both are Enhanced Power HLAI/STI FTAs with 16 channels, screw terminals, and redundancy support .
Q4: Is this FTA CE compliant?
No. The 51204168-150 is not CE compliant .
Q5: Does it support redundancy?
Yes. Redundancy is supported .
Q6: What is the mounting size?
Size B — 12.1 inches (307 mm) .
Q7: Does it support HART communication?
Yes, when paired with a compatible Smart Transmitter Interface IOP (e.g., MU-PSTX02 or MU-PSTX03). The FTA itself is a passive termination assembly; the HART communication is handled by the IOP.
Q8: Is this a current or legacy product?
The TDC 3000 / Experion PKS is a legacy/mature platform. The 51204168-150 is primarily available as spare or refurbished 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 descriptions.
| Model | Description | When to Choose |
|---|---|---|
| 51204168-150 (MC-TAIH62) | HLAI/STI FTA, 16-channel, Enhanced Power, redundant screw, conformally coated, non-CE | When conformal coating is required for harsh environments in existing TDC 3000 / Experion PKS installations |
| 51204168-100 (MU-TAIH62) | HLAI/STI FTA, 16-channel, Enhanced Power, redundant screw, non-coated | When conformal coating is not necessary (standard environment) |
| MU-TAIH23 | Enhanced Power HLAI FTA (no STI support) | When Enhanced Power is required but Smart Transmitter applications are NOT needed (must not be used for STI) |
| MU-PSTX02 / MC-PSTX02 | Smart Transmitter Interface IOP (single-variable) | The required IOP for HART communication with the MC-TAIH62 |
| MU-PSTX03 / MC-PSTX03 | Smart Transmitter Interface IOP (multivariable) | When multivariable HART transmitters require integration |
