Introduction
The Yokogawa ADV159 Digital Input Module is a high‑performance discrete input interface designed for Yokogawa distributed control systems (DCS) and modular I/O platforms. This module reliably captures ON/OFF signals from field devices such as limit switches, proximity sensors, float switches, and relay contacts, converting them into conditioned digital inputs for automation logic processing, status monitoring, and event sequencing. Built for industrial environments, the ADV159 combines high channel density with robust electrical isolation and fast response performance to support demanding automation applications.
