Yokogawa PW482-51 S2 Power Supply Module

The Yokogawa PW482-51 S2 Power Supply Module is an industrial AC input power module for Yokogawa CENTUM and FIO/FCU distributed control systems, converting 220–240 VAC input into regulated internal power for CPU, I/O, and communications modules. Engineered for high reliability, it supports dual-redundant configurations for critical process systems and mounts in rack/base slots P1–P2 via a dedicated backplane connector. It accepts 220–240 VAC ±10% at 50/60 Hz and consumes about 230 VA, delivering internal power to I/O modules and transmitters through M4 screw terminals; its function is internal system power distribution, not a standalone PSU. System compatibility includes Field Control Unit (FCU), FIO Node Unit, and Optical ESB Bus Repeater Unit, making it suitable for chemical processing, power generation, manufacturing, and process automation environments. Weight is approximately 1–2 kg depending on the exact configuration. Common replacements include Yokogawa PW482-50, PW481, and PW484.
