Product Introduction
The Yokogawa ADV161 Digital Input Module is a high-reliability, multi-channel input unit designed to capture discrete signals from field devices such as push buttons, switches, relays, and proximity sensors. As a part of Yokogawa’s I/O subsystem in the CENTUM VP and CENTUM CS 3000 process automation platforms, this module offers high-density, noise-resistant, optically isolated input capabilities.
The ADV161 is engineered for use in mission-critical industrial environments, where accuracy, safety, and long-term stability are non-negotiable. Supporting a wide range of industrial voltages and compatible with fail-safe system configurations, this module is especially suited for real-time monitoring, interlock management, and process control in large-scale manufacturing and process industries.
