Part Number: NFDV161-P51; Model: NFDV161-P51; Product Name: Yokogawa NFDV161-P51 Digital Input/Output Card; Product Series: Yokogawa CENTUM VP DCS Series, High-Reliability Digital I/O Module
Brand: Yokogawa (Yokogawa Electric Corporation, a global leader in industrial automation, measurement, and control solutions with over a century of engineering expertise. Renowned for its reliable DCS (Distributed Control System) products, Yokogawa serves key industries such as oil & gas, petrochemical, power generation, and pharmaceuticals. The NFDV161-P51 is a dedicated digital I/O card for the CENTUM VP system, designed to realize stable signal interaction between field equipment and DCS in critical industrial processes.)
Product Status: Industrial-Grade Original Equipment (Factory Calibrated, 100% Functional, RoHS Compliant); Product Category: 16-Channel Digital Input/Output (DI/DO) Card, engineered to receive digital input signals from field sensors, switches and send digital output signals to actuators, solenoid valves, enabling real-time control and status monitoring of industrial equipment.
Core Application: Exclusively used in Yokogawa CENTUM VP DCS systems for industrial scenarios including equipment on-off control, status detection, interlock protection, and sequence control. It is widely applied in petrochemical plants, oil refineries, thermal power stations, water treatment facilities, and pharmaceutical production lines, where reliable digital signal transmission and stable operation in harsh industrial environments are critical.
Core Features: 16-channel configurable DI/DO design for flexible application; Independent channel isolation to prevent cross-interference; Supports high/low level effective logic selection for DI signals and sinking/sourcing output mode for DO signals; Built-in noise suppression, ESD protection and surge protection for harsh industrial environments; Seamless integration with Yokogawa CENTUM VP system via backplane communication; Hot-swappable capability for easy maintenance without system shutdown; Self-diagnostic functions for quick fault localization.
