Honeywell MC-TAIH12 High Level Analog Input/STI Field Termination Assembly

Product Description

The Honeywell MC-TAIH12, also cataloged as the MC-TAIH12 High Level Analog Input/STI Field Termination Assembly, terminates up to 16 high-level analog input channels for Honeywell process I/O systems. The 51304337-150 part number identifies this HLAI/STI FTA version. Honeywell documentation lists it as an HLAI/STI FTA with 16 channels and compression terminals. (RuiMingSheng)

Hardware Specifications

The MC-TAIH12 belongs to Honeywell's HLAI/STI field termination hardware. Honeywell planning documentation identifies the model as a 16-channel HLAI/STI assembly with compression terminals and Size B mounting. (RuiMingSheng)

Process Analog Signal Interface

The MC-TAIH12 accepts high-level analog field signals and provides termination between field wiring and the associated process I/O hardware. The input channels can use single-ended or differential relationships to logic ground. (Western Process Computers)

For field wiring, the assembly uses compression terminals. Therefore, installation should maintain the specified terminal arrangement and preserve separation between analog signal conductors and higher-energy wiring.

The MC-TAIH12 also supports redundant configurations. Honeywell documentation identifies the HLAI/STI FTA family as supporting redundancy, while the specific 51304337-150 listing identifies 16 input points. (Western Process Computers)

Field Installation Guidelines

• Verify the complete MC-TAIH12 / 51304337-150 identification before installation.
• Confirm that the connected I/O hardware is compatible with the HLAI/STI FTA configuration.
• Wire each analog channel according to the applicable Honeywell termination diagram.
• Keep analog input wiring separated from AC power, relay output, and high-current conductors.
• Use the specified compression-terminal arrangement and check each termination for mechanical security.
• Route shielded analog cables according to the system grounding specification.
• Avoid creating multiple unintended shield-ground points that can introduce ground-loop currents.
• Before energization, verify channel polarity, signal reference, terminal assignment, and field-loop continuity.
• Do not apply an unspecified field signal or external supply until the associated I/O documentation confirms the allowable electrical range.
• The manufacturer status supplied for this item is discontinued by manufacturer.
