Yokogawa NFDV161-P50 Digital Input Module

Product Introduction

The Yokogawa NFDV161-P50 is a high-performance digital input module designed to interface digital signals from field devices into a distributed control system (DCS). Engineered for integration with Yokogawa’s STARDOM and CENTUM series control platforms, this module enables the monitoring of ON/OFF status from field equipment such as switches, sensors, and contact outputs. Built with industrial robustness, it provides high reliability and stability in harsh environments.

This module is widely adopted in critical industries, including power generation, chemical processing, oil & gas, and manufacturing, where digital input signals must be collected efficiently and accurately. It is DIN rail mountable and built for redundancy and modular expansion.
