Introduction
The Yokogawa ADV161 Digital Input Module is a high‑density, industrial discrete input interface designed for Yokogawa distributed control systems (DCS) and modular automation I/O platforms. This module accurately captures ON/OFF signals from field devices such as limit switches, proximity sensors, float switches, and relay contacts, and conditions them into reliable digital data for logic processing, alarm detection, and event sequencing. With robust electrical isolation and fast response performance, the ADV161 is well suited for demanding industrial automation environments where precise status information is essential.
