HONEYWELL MC-TAIH02 51304453-150 – High-Density Analog Input Module | Experion PKS / TDC 3000 Platform
Engineering Background
The MC-TAIH02 (P/N 51304453-150) is a high-density analog input termination assembly designed for Honeywell’s Experion PKS and legacy TDC 3000 distributed control systems. It serves as the field-side interface between process instrumentation and the C200/C300 controller infrastructure, providing reliable signal conditioning and isolation for demanding industrial environments.
Product Positioning
Targeted at process industries including refining, petrochemical, power generation, and pulp & paper, this module is a critical I/O component for plants running Honeywell DCS architectures. It is commonly sourced as a verified surplus replacement to minimize capital expenditure while maintaining OEM-grade performance and system compatibility.

System Architecture & Signal Flow
The MC-TAIH02 mounts directly into the Honeywell I/O chassis and connects to the C200/C300 controller via the FTA (Field Termination Assembly) bus. Field wiring terminates at the module’s screw terminals, where each channel passes through a 250 Ω precision shunt resistor (for current inputs) before entering the 12-bit A/D converter. Digitized values are transmitted over the I/O Link to the controller, where they are processed by the control strategy in Experion Builder. The optical isolation barrier between field and logic sides ensures that field-side faults do not propagate to the controller backplane.
Signal path: Field Transmitter → MC-TAIH02 Terminal Block → Shunt / Conditioning → A/D Converter → I/O Link → C200/C300 Controller → Experion PKS Server

Technical FAQ
Q: Is the MC-TAIH02 compatible with Experion R500 and later releases?
A: The module is hardware-compatible. Confirm firmware revision with your Honeywell system integrator for R500+ environments, as I/O configuration parameters may require validation in Experion Builder.
Q: Can this module be used in a Safety Instrumented System (SIS)?
A: The MC-TAIH02 is a standard (non-SIL-rated) analog input module. For SIS applications, Honeywell’s Safety Manager I/O modules (e.g., SM-series) are required.
Q: What is the difference between 51304453-150 and other 51304453-xxx revisions?
A: The suffix (-150) denotes the hardware revision level. Functional differences between revisions are typically minor (PCB layout, component substitutions). Confirm interchangeability with your Honeywell service engineer before installation in a validated environment.
Q: Do you provide a test report or functional verification certificate?
A: Yes. A power-on functional test report is available upon request. For critical applications, we recommend incoming inspection at your facility using a Honeywell I/O test chassis.
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 unit. Volume discounts apply for orders of 5+ units. Contact us for a tiered pricing schedule.
