Product Overview

The Yokogawa ADV161-P50 S2 is a high-density digital input module designed for the CENTUM VP integrated production control system. It functions as a critical interface within the Distributed Control System (DCS), allowing for the acquisition of discrete signals from field devices. This module is engineered for reliability in demanding industrial environments, facilitating real-time monitoring of process states.

The S2 suffix indicates a specific revision or enhancement level consistent with Yokogawa's hardware lifecycle management, ensuring compatibility with modern CENTUM VP cabinets and RIO (Remote I/O) units. With its compact form factor and efficient power management, the ADV161-P50 S2 optimizes rack space while maintaining high signal integrity.
