Product Introduction
The Honeywell 51304516-250 (MC-PSTX03) is a specialized input/output processor (IOP) card engineered for legacy and ongoing high-reliability TDC 3000 Distributed Control Systems (DCS). Functioning as a Smart Transmitter Interface Multivariable (STIM) module, it handles communication loops and digital data formatting between field-mounted smart multivariable transmitters and the central Universal Control Network (UCN).
The module processes multi-parameter field data—such as simultaneous pressure, temperature, and differential pressure measurements—allowing process engineers to capture high-precision process variables and device diagnostics directly within the TDC 3000 control architecture.

Compliance & Standards Alignment
- Manufactured in accordance with strict industrial safety and quality guidelines for critical continuous process control environments (Refining, Chemical, and Power Generation).
- Built with ruggedized internal components and protective circuit coatings to resist atmospheric sulfur compounds, humidity, and industrial corrosion.
Technical Note: When replacing or installing the MC-PSTX03 card, always confirm that the hardware (HW) and firmware (FW) revision levels match the requirements of your node module stack to prevent communication mismatches across the UCN loop.
Storage & Asset Preservation Guidelines
- Store the circuit card inside its original antistatic ESD shielding bag to protect sensitive microprocessors, memory chips, and bus transceivers from electrostatic discharge.
- Maintain warehouse storage environments where ambient temperatures are stable and relative humidity stays strictly below 60%.
- Avoid mechanical stress, bending of the board, or dropping the unit to protect the edge connector pins from alignment damage.
Physical Installation Prerequisites
- Ensure that node chassis power is completely de-energized and locked out (LOTO) in accordance with plant safety procedures before inserting or removing the card.
- Guide the card carefully along the enclosure card-guides into its designated backplane slot, ensuring parallel insertion before pressing firmly to seat the rear connectors.
- Secure the top and bottom retention latches completely to maintain reliable backplane electrical continuity and structural stability.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this Honeywell interface card?
A: Industrial process control system cards, distributed control network modules, and electronic parts generally classify under HS code 8538.90 (Parts suitable for use solely or principally with control apparatus). Confirm exact details with your customs broker.
Q: Is this card compatible with newer Experion PKS systems directly?
A: The 51304516-250 is specifically tied to the legacy TDC 3000 / UCN architecture. Migration paths to Experion PKS typically require dedicated gateway solutions or native I/O migration hardware. Check your system architecture layout before procurement.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market availability, inventory condition (Surplus vs. Rebuilt), and hardware revision tracking; contact our technical sales desk for a formal, time-sensitive quotation.
