Honeywell MC-TAIH52 51304337-250 Analog Input Module

The Honeywell MC-TAIH52 51304337-250 is a high-level analog input module engineered for precision signal acquisition in demanding industrial control and automation environments. Designed as a Field Termination Assembly (FTA) board, it serves as a critical interface within the Honeywell C300 DCS architecture, ensuring reliable data collection even in electrically noisy conditions.

Hardware Specifications

4-20 mA HART Loop Protocol Connectivity

This module is specifically designed to support 4-20 mA HART loop protocol connectivity for intelligent field devices. It features 16 differential input channels with a high common-mode rejection ratio of 70 dB (dc to 60 Hz) and supports a wide input voltage range of ±30 volts with high input impedance. Within the Honeywell system configuration, this FTA board connects to the PM I/O card (such as the CC-PAIH01 analog input card) via the I/O Link Interface Module (IOLIM), facilitating seamless communication with HART-enabled field instrumentation.

Field Installation Guidelines

1. Verify the target IOLIM slot and ensure the corresponding PM I/O card (e.g., CC-PAIH01) is properly seated and configured in the Control Builder software.

2. Route field wiring to the FTA board terminals, ensuring that shielded cables are used for 4-20 mA HART signals to maintain signal integrity.

3. Terminate all field wires according to the FTA wiring diagram, verifying correct polarity for differential input channels.

4. Secure the FTA board to the IOLIM interface and tighten all retaining hardware to prevent vibration-related loosening.

5. Perform loop testing and verify HART communication with the field device using the Control Builder monitoring environment before returning the system to active control.
