YOKOGAWA PW402 Power Supply Module – CENTUM VP / CS 3000 Distributed Control System
In a continuous process plant — whether a refinery, chemical reactor, or power generation facility — an unexpected power supply failure doesn’t just halt production. It can trigger cascading shutdowns, compromise safety interlocks, and cost tens of thousands of dollars per hour in lost output. The YOKOGAWA PW402 Power Supply Module is the critical backbone that keeps your CENTUM VP or CS 3000 DCS field control station energized, stable, and protected against the voltage fluctuations that threaten process continuity.
The PW402 occupies a well-established position within YOKOGAWA’s CENTUM series power supply lineup. Designed specifically for the FCS (Field Control Station) and associated I/O modules, it delivers regulated DC power with the redundancy-ready architecture that global process industries demand. From petrochemical complexes in the Middle East to pharmaceutical manufacturing in Europe, the PW402 has earned its reputation as a dependable, long-lifecycle component in mission-critical automation infrastructure.
