Yokogawa ADV161-P50 Digital Input Module

Overview

The Yokogawa ADV161-P50 is a 64-channel digital input (DI) module designed for CENTUM VP and CENTUM CS 3000 control systems. Part of the FIO (Field I/O) subsystem, this module provides high-density acquisition of 24 V DC ON/OFF signals from field devices such as switches, relays, and interlock circuits. The P50 variant includes pushbutton input support, does not have status indicators, and lacks explosion protection, making it ideal for standard industrial environments.
