Honeywell MU-TAMT03 (51309223-125) – Analog Multiplexer Module | TotalPlant TPS / Experion PKS
Engineering Background: The Honeywell TotalPlant Solution (TPS) platform has been the backbone of process automation in refining, petrochemical, and power generation facilities for decades. The MU-TAMT03 Analog Mux Module is a critical I/O component within this architecture, enabling high-density analog signal acquisition from field instruments through a multiplexed channel design — reducing wiring complexity while maintaining signal integrity across the control loop.
Product Positioning: Designed for procurement engineers and DCS maintenance teams requiring a verified, drop-in replacement for the Honeywell TPS platform. The MU-TAMT03 (P/N 51309223-125) is a factory-original module sourced from certified surplus channels, fully tested, and ready for immediate integration into existing TPS cabinets without firmware reconfiguration.

System Architecture & Signal Flow
The MU-TAMT03 operates within the Honeywell TPS I/O subsystem, interfacing between field-mounted transmitters and the High-Performance Process Manager (HPM) or equivalent controller. Analog signals from multiple field instruments are sequentially sampled via the internal multiplexer, digitized, and transmitted over the TPS data highway to the operator station. This architecture supports both 4–20 mA and millivolt-level thermocouple/RTD inputs depending on the associated termination assembly configuration.

Technical FAQ
Q: Is the MU-TAMT03 compatible with Experion PKS as well as TPS?
A: Yes. The MU-TAMT03 is compatible with both the legacy TotalPlant Solution (TPS) and Experion PKS platforms that share the same I/O card cage architecture.
Q: What is the difference between P/N 51309223-125 and other 51309223 variants?
A: The suffix (-125) denotes the specific hardware revision and configuration. Always match the full part number when ordering to ensure correct termination and firmware compatibility.
Q: Can Konmask provide a test report before shipment?
A: Yes. Pre-shipment test reports and high-resolution photos of the actual unit are available upon request at no additional charge.
Q: What is the typical lead time?
A: In-stock units ship within 1–2 business days. If not in stock, sourcing lead time is typically 5–15 business days depending on global availability.
