MC-TAIH14 51305887-150 | Honeywell High-Level Analog Input FTA Module

Product Overview

The Honeywell MC-TAIH14 (Part Number: 51305887-150) functions as a High-Level Analog Input Field Termination Assembly (FTA) designed for high-density signal acquisition. This module interfaces 16 field-side 4-20mA signals directly with the Honeywell control environment, providing integrated HART communication pass-through for smart instrument diagnostics. We supply this unit in 100% Brand New, original factory condition, ensuring your mission-critical process loops benefit from the highest available signal fidelity and zero-hour operational life.

Technical Specifications

Engineering Advantages

• High-Precision Data Acquisition: The 0.05% input accuracy ensures micro-level precision for flow, pressure, and temperature loops. This ultra-low margin of error eliminates the data drift commonly found in lower-tier I/O interfaces.

• Smart Instrument Integration: The module supports bi-directional HART communication. This allows maintenance teams to access field device diagnostics, configuration data, and secondary variables without disconnecting wiring or using external handheld communicators.

• Superior Noise Mitigation: 500V galvanic isolation shields the internal control bus from field-side electrical surges and common-mode noise. This protection prevents ground loops and safeguards the central processor from catastrophic electrical failure in lightning-prone or high-EMI environments.

• Extended Thermal Performance: The hardware maintains linear accuracy across a broad temperature range (-20°C to 60°C). This thermal resilience permits installation in non-climate-controlled marshalling cabinets and remote instrument buildings.

• Space-Optimized Footprint: The compact 120mm profile allows for high-density mounting on standard I/O carriers. This simplifies cable management and reduces the total number of marshalling cabinets required for large-scale facility upgrades.

FAQs

• Does this module support both active and passive 4-20mA loops? The MC-TAIH14 interfaces with standard 4-20mA transmitters. Ensure your field wiring matches the specific powering requirements (loop-powered vs. self-powered) as defined by your Honeywell I/O processor configuration.

• Is this a genuine Honeywell original part? Yes. We deliver the MC-TAIH14 in 100% Brand New condition, sourced directly through authorized channels to guarantee authenticity, full factory specifications, and original packaging.

• How does the HART support function within the DCS? The module provides a transparent data path for the HART digital signal superimposed on the 4-20mA analog loop. This enables your asset management software to communicate directly with smart field devices for real-time health monitoring.

• What are the grounding requirements during installation? Properly terminate the shield wires at the FTA grounding bar to maximize the effectiveness of the 500V isolation. This practice ensures that electromagnetic interference does not compromise the high 0.05% accuracy rating.
