YOKOGAWA PW482-50 S2 Redundant Power Supply Module – CENTUM VP / CS 3000 Series
Imagine a continuous process plant — a refinery, a chemical reactor, or a pharmaceutical batch line — running at full capacity when the control system’s power supply silently fails. Within milliseconds, field instruments lose power, I/O cards go offline, and the DCS loses communication with hundreds of control loops. The result: unplanned shutdown, product loss, safety incidents, and regulatory scrutiny. The YOKOGAWA PW482-50 S2 Power Supply Module exists precisely to prevent this scenario. Engineered for mission-critical DCS environments, it delivers stable, conditioned DC power to field control stations with the reliability that 24/7 industrial operations demand.
The PW482-50 S2 occupies a strategic position within YOKOGAWA’s CENTUM VP and CS 3000 distributed control system architecture — the world’s most widely deployed DCS platform in oil & gas, petrochemical, and power generation industries. As a redundant-capable power supply module, the PW482-50 S2 supports hot-standby configurations that eliminate single points of failure at the power layer. Its S2 suffix designates the second-generation hardware revision, incorporating enhanced EMI filtering and improved thermal management over its predecessor, making it the preferred replacement and upgrade module for legacy CS 3000 installations transitioning to CENTUM VP.
