Yokogawa NFPW444-50 Part # NFPW444-50 | Redundant DCS Power

Yokogawa NFPW444-50 24V DC Field Control Station Power Supply Module

The NFPW444-50 (Model: NFPW444-50) is a high-efficiency DC-to-DC power supply module designed for Yokogawa’s CENTUM VP and CS 3000 Field Control Stations (FCS). Specifically engineered to accept a 24 V DC input, this module is critical for industrial sites utilizing centralized battery backup systems or DC power grids. The NFPW444-50 (Part Number: NFPW444-50) provides a highly stable +5.1 V DC output to energize control processors and internal communication circuitry, ensuring deterministic system performance.

As a "Basic Type" with the -50 suffix, this module is designed for standard industrial environments where explosion protection is not required. It is built for high-availability architectures, supporting dual-redundant configurations. In redundant mode, two NFPW444-50 (Model: NFPW444-50) modules share the load across the backplane; if a failure is detected in one unit, the second module assumes the full 7.8 A rated current load without a voltage dip, preventing volatile memory loss or processor resets.

Detailed Technical Specifications

The NFPW444-50 (Model: NFPW444-50) offers precise voltage regulation and robust current delivery for critical DCS infrastructure.
