Yokogawa PW484-51 S1 CENTUM VP 24V DC Power Supply Module

The PW484-51 (Model: PW484-51) is a specialized power supply module engineered for the Yokogawa CENTUM VP and CS 3000 Distributed Control Systems (DCS). Operating as a core infrastructure component, the PW484-51 (Style S1) converts input power into highly stable, regulated 24V DC to energize control processors, I/O modules, and complex communication interfaces.

This "S1" hardware revision represents an updated design over the legacy PW484-50, offering improved component longevity and thermal efficiency. The module is built for mission-critical reliability, supporting dual-redundant configurations. In a duplex setup, two PW484-51 (Part Number: PW484-51) modules share the system load; if one fails, the partner module assumes full power delivery instantaneously, ensuring zero process downtime. Note that this specific unit is provided without the front cover, making it ideal for integration into existing secured racks or for specific maintenance replacements where the original cover is retained.
