Description

The Honeywell MC-TAIH14 (Part Number: 51305887-150) is a High Level Analog Input HART Field Termination Assembly (HLAIHART FTA) designed for integration within Honeywell Process Manager (PM), Advanced Process Manager (APM), High Performance Process Manager (HPM), and Experion Process Knowledge System (PKS) I/O architectures. Acting as the direct physical interface between field-mounted process transmitters and system Input/Output Processors (IOPs), the assembly channels 16 analog input signals while facilitating pass-through Highway Addressable Remote Transducer (HART) digital communication.

Featuring a 16-channel architecture with compression-style terminal blocks, the MC-TAIH14 enables clean termination of 4-20 mA field loops from transmitters measuring pressure, flow, level, and temperature. The board is built on Honeywell Size B mounting dimensions, providing physical layout compatibility for standard cabinet channel mounting alongside adjacent process termination assemblies.

The MC-TAIH14 assembly (51305887-150) establishes reliable signal paths for real-time regulatory control loops and asset management functions. By interfacing high-level analog signals directly to system I/O modules, it simplifies cabinet wiring, shields control room electronics from field-side interference, and provides access points for HART hand-held communicators and asset management software suites.

Designed for high-density control environments, the board functions seamlessly across redundant and non-redundant system hardware layouts. Its structured terminal arrangement reduces field installation time and ensures long-term operational continuity across continuous process automation plants.

Features

• 16-Channel Capacity: Supports up to 16 individual high-level analog input channels for high-density field signal processing.
• HART Protocol Support: Facilitates simultaneous transmission of standard 4-20 mA analog signals and HART digital communications for smart field instrument diagnostics.
• Compression Terminal Blocks: Equipped with reliable compression-type (C) wiring terminals to simplify field instrument loop connections.
• Size B Mounting Form Factor: Designed in standard Honeywell Size B dimensions for uniform cabinet layout and channel mounting integration.
• System IOP Compatibility: Integrates directly with Honeywell High Level Analog Input (HLAI) Processors via standard pre-fabricated I/O interface cables.

Applications

• Smart Field Transmitter Interfacing: Terminating 4-20 mA HART-enabled pressure, temperature, differential pressure, and level transmitters in process control loops.
• Asset Management Routing: Routing digital HART variables and field device diagnostic parameters to maintenance software systems without interrupting control loops.
• DCS Cabinets Integration: Structuring high-density analog signal wiring within standard Honeywell TPS and Experion Process Knowledge System (PKS) enclosures.

Installation Guidelines

1. Pre-Installation Verification: Inspect the assembly part number (MC-TAIH14 / 51305887-150) to verify matching model specifications and physical integrity prior to mounting.
2. Mounting: Snap or latch the Size B assembly into the dedicated FTA mounting channel inside the cabinet enclosure.
3. Power Isolation: De-energize loop power and field-side circuits before wiring to prevent arc flash or electrical damage.
4. Field Loop Connection: Connect field instrument wiring to the compression terminals, adhering to polarity markings for each of the 16 analog channels.
5. System Interface Cable: Connect the pre-fabricated Honeywell I/O interface cable between the FTA board connector and the designated IOP slot in the cardfile.
6. Shield Bonding: Ensure field cable shields are properly grounded according to plant EMC and Honeywell system installation rules.
7. Commissioning Checks: Measure loop current on active channels, confirm analog-to-digital signal scaling at the controller, and test HART pass-through communication using a HART communicator.
