Overview
The Honeywell TK-IAH161 analog input module is a precision 16-channel signal conditioning and acquisition device engineered for Honeywell Experion® PKS C200 and C300 control systems. This high-level analog input module converts field instrument signals—voltage (0–10 V, 1–5 V) and current (4–20 mA) ranges—into high-resolution digital data for real-time process monitoring and control. With integrated cold junction compensation, filtering, and per-channel scaling, the TK-IAH161 delivers accurate, noise-resistant signal capture across diverse industrial automation and process control applications.
