Honeywell TC-IAH161 High Level Analog Input | TDC 3000

Honeywell TC-IAH161 TC-IAH16I High Level Analog Input Module

Product Description

The TC-IAH161 (TC-IAH16I) is a high-density, high-level analog input module engineered for the Honeywell Experion PKS and legacy TDC 2000/3000 control systems. Designed to interface with a wide variety of field transmitters, this module features 16 individual channels capable of processing both voltage and current signals. It converts raw analog data into precise 16-bit digital values, which are then published to the controller every 250 milliseconds to support real-time process monitoring.

To ensure survival in high-interference industrial settings, the TC-IAH161 (TC-IAH16I) is built with significant galvanic isolation (tested at 2550V DC) and high RFI immunity. This makes it an ideal choice for critical infrastructure where signal integrity is paramount, such as in petrochemical refining, power generation, and large-scale manufacturing. The module utilizes the TC-TBCH 36-position terminal block for secure and organized field wiring.
