Product Overview
The Honeywell MC-TAIH53 (Part No. 51309138-275) is a high-level analog input Field Termination Assembly (FTA) used in Honeywell Experion PKS and Series C distributed control systems (DCS).
It is designed to receive and condition multiple 4–20 mA analog signals from field instruments such as pressure transmitters, flow meters, temperature sensors, and level transmitters. The module ensures accurate signal transmission from field devices to the control system for real-time process monitoring and control.
This model is widely used in high-density industrial analog input applications where reliability, signal integrity, and structured wiring are required.
