Yokogawa ADV151-E63/D6A00 32-Channel Isolated Digital Input Module

Overview

The ADV151-E63/D6A00 is a high-density digital input module developed by Yokogawa for its Field Input/Output (FIO) platform. It is engineered to reliably acquire discrete 24 V DC signals from field devices and deliver them to Yokogawa distributed control systems with high accuracy and determinism. The module is optimized for use in CENTUM VP and CS 3000 environments where redundancy, fast signal detection, and event traceability are critical.

Designed with isolated input circuitry and compact mechanical dimensions, this module supports stable operation in electrically noisy industrial environments while minimizing control cabinet space.

Functional Characteristics

The ADV151-E63/D6A00 accepts ON/OFF status signals from a wide range of dry contacts and voltage-driven devices, including limit switches, proximity sensors, pushbuttons, and interposing relays. Each channel is electrically isolated to prevent ground loops and reduce the impact of external interference.

Integrated support for dual-redundant configurations allows the module to be deployed in high-availability systems without introducing single points of failure. In addition, high-speed input scanning enables accurate sequence-of-events recording, supporting post-event analysis and operational diagnostics.
