Honeywell TC-IAH161 Experion LS High Level Analog Input Module

Description

The Honeywell TC-IAH161 is a 16-channel high-level analog input module designed for integration with industrial process control systems. This device acquires single-ended voltage and current signals from field devices, delivering high-resolution digital data conversion for automated monitoring and control applications. Featuring a publish rate of 250 msec, the TC-IAH161 processes inputs across flexible range settings while maintaining precise signal accuracy and system isolation.

Features

• Accepts 16 single-ended analog input channels.
• Supports multiple input voltage ranges including +/- 10.25 V, 0 to 10.25 V, and 0 to 5.125 V.
• Handles current measurement from 0 to 20.5 mA using an internal nominal 249 ohm resistor.
• Provides 16-bit resolution across all voltage and current input ranges.
• Incorporates 100% factory-tested user-to-system isolation up to 2550 VDC for 1 second.
• Interfaces via a 36-position TC-TBCH connection terminal block.

Applications

• Distributed Control System (DCS) process monitoring.
• Industrial automated field sensor acquisition.
• High-density analog input loop interfacing.
• Voltage and 4-20 mA loop current monitoring.

Technical Specifications

Installation Guidelines

• Mounting: Ensure proper chassis seating and secure the module into the designated slot.
• Wiring: Connect field signals using the approved TC-TBCH 36-position terminal block. Verify that signal wires match the channel assignments for voltage or current loops.
• Shielding: Use shielded twisted-pair cabling for sensor wiring to reduce electromagnetic interference. Ground shields at the designated system earth ground point.
• Heat Dissipation: Maintain adequate enclosure ventilation to accommodate the module's maximum 4.1 W power dissipation.
