Product Overview

The Yokogawa PW482-10 serves as the primary energy backbone for the CENTUM CS3000 and CENTUM VP distributed control systems. This module converts AC line voltage into highly regulated 24 VDC power to drive controllers, I/O modules, and critical communication interfaces. We supply this unit as 100% Brand New and Original, featuring the ISA Standard G3 option for deployment in corrosive industrial environments.

Engineering Advantages

ISA G3 Environmental Hardening: The PW482-10 features advanced conformal coating that meets ISA Standard G3. This protection prevents copper and silver corrosion in facilities with high concentrations of hydrogen sulfide (H2S) or chlorine gas, common in pulp & paper and chemical refining.
True Fault Tolerance: When you install two PW482-10 modules in a single rack, the hardware automatically enters a redundant load-sharing mode. If one unit fails, the remaining module immediately assumes the full load without any voltage drop, ensuring zero process interruption.
Industrial Temperature Resilience: Unlike standard power units, the "-1" variant operates reliably between -20°C and +70°C. This wide thermal window allows installation in non-climate-controlled marshaling cabinets or remote I/O shelters in extreme climates.
Active Diagnostics: Integrated monitoring circuits track output health in real-time. The front-panel LEDs alert maintenance personnel to internal faults or input power loss, facilitating rapid hot-swappable replacement before a secondary failure occurs.

FAQs

Q: Can I replace a standard PW482 with the PW482-10?

A: Yes. The PW482-10 includes the ISA G3 coating and extended temperature range, making it a superior, backward-compatible replacement for standard PW482 modules in CENTUM racks.

Q: Does this module require manual voltage switching for 110V vs 220V?

A: No. The internal circuitry handles the 100–240 VAC input range automatically. Always ensure your input wiring complies with Yokogawa's grounding specifications to prevent common-mode noise.

Q: How does the module indicate a fault to the DCS?

A: The PW482-10 communicates its status through the backplane to the CENTUM system software. Additionally, the "FAIL" LED on the front plate illuminates if the output voltage falls outside the regulated 24 VDC window.
