Product Overview

The Honeywell TC-IAH161 is a precision-engineered High Level Analog Input (HLAI) module designed for the Experion® Chassis I/O environment. This high-density component features 16 independent channels, enabling the simultaneous monitoring of a vast array of industrial sensors and process variables. It serves as a central data acquisition hub within a Distributed Control System (DCS), converting diverse analog signals from field instrumentation into high-resolution digital data for real-time logic processing.

Built to maintain signal integrity in electrically volatile environments, the TC-IAH161 utilizes advanced filtering and isolation techniques. Its architecture is optimized for 1756-style rack mounting, providing a compact footprint without sacrificing the rigorous safety standards required for heavy industrial and commercial automation.

Key Technical Characteristics

The TC-IAH161 is distinguished by its high-bit resolution and robust resistance to external interference.

• Multi-Range Signal Compatibility: Supports flexible input configurations including 0–20.5 mA current loops and voltage ranges of 0–5.125 VDC or 0–10.25 VDC.

• 16-Bit Precision: Delivers high-granularity data acquisition across all channels, ensuring that minute fluctuations in process variables are accurately captured and reported.

• Exceptional RFI Immunity: Engineered to operate reliably in high-noise areas, maintaining an error margin of less than 2.0% even when subjected to significant Radio Frequency Interference.

• Advanced Galvanic Isolation: Features user-to-system isolation tested at 2550 VDC, protecting internal controller circuitry from field-side voltage spikes and transients.

• Rapid Data Refresh: Provides a module publish rate of 250 milliseconds, ensuring that the control system receives low-latency updates for time-sensitive process monitoring.

• Input Impedance Management: Includes a 249-ohm nominal input impedance for current measurements, simplifying integration with standard 4-20mA field transmitters.
