Product Introduction
The Yokogawa PW482-S01 Power Supply Module is a dedicated industrial-grade power unit designed specifically for Yokogawa Distributed Control Systems (DCS), including FCU, FIO Node Units, and Optical ESB Bus Repeater Units.
Unlike general-purpose power supplies, this module is tightly integrated into Yokogawa system architecture, ensuring precise, stable, and noise-free DC power delivery to critical control and I/O components. It plays a foundational role in maintaining system continuity, especially in high-availability industrial environments.
