Product Overview

The PW502 (Model: PW502) is a high-availability power supply module specifically engineered for Yokogawa’s CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). Operating as a critical infrastructure component within the Field Control Station (FCS) and bus repeater assemblies, the PW502 (Style S1) provides highly regulated DC power to control processors, I/O modules, and internal communication circuitry, ensuring deterministic system performance in mission-critical automation environments.

To guarantee maximum plant uptime, the PW502 (Part Number: PW502) supports dual-redundant configurations. In a duplex setup, two modules operate in parallel to share the system load. Should one unit detect an internal hardware fault or a loss of input voltage, the secondary unit assumes the full load instantaneously with a "bumpless" transition. This fault-tolerant architecture is vital for industries such as oil refining, chemical processing, and power generation, where even a momentary power dip can lead to costly system trips or unsafe conditions.
