Yokogawa NFDV161-P00 S2 16-Channel Digital Input Module

Product Description

High-Speed Digital Status Acquisition

The Yokogawa NFDV161-P00 S2 (Model NFDV161) is a precision digital input module designed for the Yokogawa STARDOM autonomous controller series, including the FCN, FCN-500, and FCJ systems. This module serves as a critical interface for acquiring binary status signals from field equipment such as pressure switches, limit switches, and sensor contacts. It features 16 independent input channels configured for 24 V DC logic, ensuring high-speed data acquisition with a fast 10 ms refresh cycle for real-time process monitoring.

Noise Immunity and Industrial Protection

To ensure reliable operation in electrically noisy industrial environments, the NFDV161-P00 S2 is equipped with high-grade optocoupler isolation. This galvanic separation prevents electrical surges or electromagnetic interference (EMI) on one channel from propagating to other channels or the system backplane. With a high input impedance of 10 kΩ, the module minimizes current draw from field devices while maintaining signal integrity across long cable runs. The "S2" hardware revision indicates an updated hardware style, optimized for long-term reliability in mission-critical applications such as oil and gas production and chemical manufacturing.
