The Yokogawa PW482-11 S2 is a high-reliability AC/DC power supply module used in Yokogawa CENTUM CS / CS 3000 distributed control systems (DCS).
It provides stable power conversion from 220–240 V AC input into regulated DC outputs, supplying essential power to controllers, I/O modules, and communication units within industrial automation systems. The “S2” suffix represents a hardware revision version, typically improving reliability, safety compliance, or internal circuit optimization.
This module is widely deployed in oil & gas, petrochemical, power generation, and continuous process industries, where uninterrupted system power is critical.
