HART Compatible Analog Input Card | Honeywell MC-TAIH14

Product Overview

The Honeywell MC-TAIH14 (Part Number 51305887-150) serves as a high-integrity High Level Analog Input (HLAI) Board for Honeywell Experion PKS and legacy TDC systems. This module provides 14 isolated channels designed to capture precise 4-20mA or 0-10VDC signals from field transmitters, including flow meters, pressure transducers, and temperature sensors. We supply this board as 100% brand new and factory-original, featuring integrated HART (Highway Addressable Remote Transducer) protocol support. The MC-TAIH14 enables the control system to extract rich diagnostic data from smart field devices while maintaining high-speed, 12-bit signal conversion for real-time process monitoring.

Technical Specifications

The MC-TAIH14 coordinates sophisticated analog data acquisition through these industrial-grade parameters:

Engineering Advantages

• HART Passthrough Capability: The MC-TAIH14 supports HART digital communication superimposed on the 4-20mA analog signal. This allows maintenance teams to perform remote calibration, access secondary variables, and monitor device health directly from the Experion Station, significantly reducing the need for field-based handheld communicators.

• Superior Signal Integrity: Independent channel-to-channel isolation eliminates ground loops and minimizes common-mode noise. This architecture ensures that a faulty transmitter or a localized electrical surge on one loop does not corrupt the data on the remaining 13 channels or damage the central I/O backplane.

• Deterministic High-Speed Acquisition: The 12-bit A/D converter executes high-speed sampling to support real-time control loops. This rapid response is critical for managing fast-acting process variables in turbine control, surge protection, and high-pressure steam headers where millisecond data accuracy determines plant safety.

• Universal Input Flexibility: The board accommodates both current (loop-powered or self-powered) and voltage inputs. This versatility allows engineers to standardize on the MC-TAIH14 across the entire facility, regardless of the variety of field instrument output types, simplifying spare parts management.

FAQs

• Does the MC-TAIH14 support redundant configurations?

  Yes. You can install the MC-TAIH14 in redundant pairs within a compatible Honeywell rack. The system automatically synchronizes the analog data between the primary and secondary modules to ensure uninterrupted process visibility during a hardware failover.

• Is this board a direct replacement for non-HART analog modules?

  In most cases, yes. The MC-TAIH14 provides the same fundamental 4-20mA acquisition as older modules but adds the benefit of HART digital data. You should verify your existing I/O processor (IOP) firmware to ensure it supports the extended HART diagnostic features.

• What mounting options are available for this module?

  The MC-TAIH14 installs directly into a standard Honeywell High-Performance Process Manager (HPM) or I/O rack. The modular card design facilitates hot-swapping (in redundant systems), allowing for maintenance without requiring a total system shutdown.
