FAQ

Q1: What is the Honeywell 51304516-200 used for?
It is a 16-channel Smart Transmitter Interface Multivariable (STIM) IOP for the Honeywell TDC 3000 / TPS / Experion PKS DCS. It acts as a bidirectional gateway between HPM/APM/C300 controllers and field-mounted multivariable HART smart transmitters, extracting multiple process variables and diagnostics from a single device .

Q2: How many channels does it have?
16 high-level analog input channels, configurable as single-ended or differential .

Q3: What is the difference between 51304516-200 (MU-PSTX03) and 51304516-100 (MU-PSTX02)?
The -200 (MU-PSTX03) is the multivariable STIM designed for multivariable transmitters (e.g., SMV 3000), and it is CE compliant. The -100 (MU-PSTX02) is the standard single-variable STI and is not multivariable-capable. The -200 replaces the -100 in CE-compliant installations .

Q4: What is the difference between 51304516-200 and 51304516-250?
The -200 (MU-PSTX03) is CE compliant and non-conformally coated. The -250 (MC-PSTX03) is CE compliant and conformally coated for harsh or corrosive environments .

Q5: Does it support redundancy?
Yes. It fully supports redundant IOP configurations (dual IOP to the same FTA) for high-availability systems .

Q6: Does it support HART communication?
Yes. It uses the Honeywell digital enhanced protocol (bidirectional HART overlay on the 4–20 mA loop) to extract multivariable data and perform remote configuration/diagnostics .

Q7: Is this module conformally coated?
No. The 51304516-200 is not conformally coated (standard industrial edition). For conformal coating, choose the 51304516-250 (MC-PSTX03) .

Q8: What are the dimensions and weight?
Conflicting sources: One detailed source cites 68 × 162 × 165 mm and ~0.75 kg ; other listings cite 30 × 320 × 276 mm and 0.78 kg . Another cites 0.69 kg . Verify against official Honeywell documentation for your exact revision.

Q9: Is it hot-swappable?
One source states it supports online hot-swapping , while another explicitly states it cannot be hot-swapped and must be replaced with the system powered down . Verify this critical operational detail against official Honeywell documentation before maintenance planning.

Q10: Is this a current or legacy product?
The TDC 3000 / TPS is a legacy platform, though the module is also listed for Experion PKS C200/C300 . It is primarily available as spare or refurbished stock. Confirm availability with Honeywell or an authorized distributor.

Q11: Where can I get technical documentation?
Official Honeywell documentation, or an authorized distributor, is the authoritative source for specifications and compatibility.
