Product Introduction
The Yokogawa ADV169 Digital Input Module is a high-performance discrete input module engineered for use in Yokogawa’s CENTUM VP, CENTUM CS 3000, and ProSafe-RS control and safety systems. Designed to capture digital signals from field devices such as limit switches, push buttons, proximity sensors, and relay outputs, the ADV169 ensures reliable status monitoring across industrial automation processes.
Equipped with 16 optically isolated digital input channels, this module supports 24 V DC logic levels and dry contact signal types. The ADV169 is ideal for fail-safe system architectures, delivering fast response times, signal integrity, and advanced diagnostic capabilities. It is particularly well-suited for demanding sectors like oil & gas, chemical processing, utilities, and power generation, where continuous operation, safety, and real-time signal acquisition are mission-critical.
