ADV151-DI32 | Yokogawa | 32-Channel Digital Input Module

Product Description

The ADV151-DI32 is a 32-point digital input module engineered by Yokogawa for use in CENTUM VP and CENTUM CS 3000 distributed control systems. It is designed to reliably acquire 24 V DC discrete signals from field devices and deliver deterministic, time-accurate status data to the control processor.

This module supports high-speed signal detection and sequence-of-events processing, making it suitable for applications where accurate event timing and system availability are critical. Its compact rack-mount design allows dense I/O configuration within field control units while maintaining maintainability and long-term stability in harsh industrial environments.

Key Technical Characteristics

The ADV151-DI32 provides 32 independent digital input channels optimized for standard 24 V DC field signals. Each channel is capable of detecting rapid ON/OFF transitions with consistent response time, enabling precise monitoring of mechanical and electrical contacts.

The module is designed for use in redundant system architectures, supporting high-availability configurations within Yokogawa DCS platforms. Integrated sequence-of-events functionality allows input changes to be time-stamped by the system, supporting post-event analysis, diagnostics, and compliance requirements.
