HONEYWELL TC-IAH161 Product Specification
1. Product Overview
The HONEYWELL TC-IAH161 is a high-precision analog input module specifically designed for Honeywell Experion PKS (Process Knowledge System) and TPS (Total Plant Solution) control systems. As a fundamental data acquisition component in industrial automation, it specializes in collecting and conditioning continuous analog signals from field sensors—such as pressure, temperature, level, and flow transmitters—converting them into digital signals for the control system to process. Widely used in oil & gas, petrochemical, chemical, and power generation industries, this module ensures accurate and reliable signal transmission, providing a solid basis for precise process control and operational optimization.
Integrated with advanced signal conditioning circuits and multi-layer isolation technology, the TC-IAH161 maintains exceptional measurement accuracy and strong anti-interference performance even under harsh industrial conditions (electromagnetic interference, temperature fluctuations, and voltage instability). It complies with IEC 61131-2 and UL 508 industrial standards, ensuring seamless integration with Honeywell’s control systems and meeting strict safety and reliability requirements of industrial sites.

3. Key Features
3.1 High Precision & Fast Sampling
With ±0.05% full-scale accuracy and minimal temperature drift, the module ensures consistent and precise signal conversion, which is crucial for processes requiring strict parameter control (e.g., chemical reaction temperature regulation). The 100 samples/second per channel sampling rate enables real-time capture of rapid signal changes, supporting dynamic process monitoring in high-speed production lines.
3.2 HART Compatibility & Smart Function
Compliant with HART 7.0 protocol, the TC-IAH161 enables bidirectional communication with HART-enabled smart transmitters. This allows remote configuration of transmitters, retrieval of diagnostic data (e.g., sensor health, calibration status), and adjustment of measurement ranges without on-site intervention, significantly reducing maintenance workload and downtime.
3.3 Robust Isolation & Diagnostics
Multi-layer isolation design (channel-to-channel and channel-to-system) effectively suppresses electromagnetic interference and prevents signal cross-talk, ensuring stable operation in noisy industrial environments. Built-in self-diagnostics monitor channel faults, open circuits, and power anomalies in real time, sending alerts to the control system for proactive troubleshooting.
