Product Overview

The Honeywell MC-TAIH22, part number 51204170-250, is a precision-engineered High Level Analog Input (HLAI) module designed for the TDC 3000 and Experion PKS Distributed Control Systems. This module acts as a high-density data acquisition interface, capable of processing up to 16 independent channels of high-level analog signals. As a core component of the MU-T series, the MC-TAIH22 is built to convert standard industrial signals—typically 1-5V or 4-20mA via a shunt—into high-resolution digital data for process monitoring and control. Its architecture prioritizes signal isolation and noise rejection, ensuring that critical process variables remain accurate even in electrically saturated industrial environments.

Industrial Utility and Deployment

In Petrochemical and Refining Facilities, the MC-TAIH22 is deployed to aggregate high-level signals from temperature transmitters and pressure transducers. The module’s robust thermal management allows it to be installed in field-mounted cabinets where temperatures can fluctuate significantly, providing consistent data streams to the central control room for safety monitoring.

Within Power Generation and Utility Management, this module serves as a critical link in the monitoring of steam cycle efficiency. By handling multiple inputs simultaneously, it allows for the real-time calculation of heat rates and turbine performance. Its wide voltage tolerance ensures that the module remains operational during minor power fluctuations, maintaining the integrity of the plant’s automation loop.

For Heavy Manufacturing and Smelting, the MC-TAIH22 is utilized for its high electromagnetic interference (EMI) resistance. In environments with high-voltage machinery, this module filters out signal noise to provide a clean data set for PLC and DCS logic solvers. The compact Series MU-T form factor enables facilities to expand their monitoring capabilities without requiring extensive cabinet redesigns, facilitating cost-effective system upgrades and maintenance.
