Introduction
The Yokogawa ADM11‑S3 Contact Input Module is an industrial discrete input interface designed for Yokogawa distributed control systems (DCS) and modular I/O platforms. It captures contact closure and digital on/off signals from field devices—such as switches, relays, float sensors, and proximity contacts—and conditions them for use in automation logic, status monitoring, and alarm processing. Built for rugged environments, the ADM11‑S3 delivers reliable digital input acquisition with strong electrical noise immunity and easy system integration.
