Product Overview

The PW484-10 is a DC-to-DC power supply module designed for Yokogawa CENTUM VP Field Control Units (FCU). Unlike AC-input modules, it operates from a 24V DC primary source, making it ideal for centralized battery systems, solar-powered stations, or backup DC infrastructures. The module provides regulated DC bus voltages for processors and I/O cards, ensuring reliable operation while protecting sensitive electronics from noise and voltage transients.

Technical Specifications

Key Functional Advantages

• Redundant Reliability: Supports duplexed operation; if one module fails, the other instantly assumes the full load.

• DC Infrastructure Integration: Enables direct powering from industrial battery banks or DC backup systems.

• Hot-Swap Maintenance: Faulty modules can be replaced without shutting down the FCU or interrupting the process.

• Ruggedized Protection: Safeguards against input polarity reversal, overvoltage, and overcurrent conditions.

FAQ

Can I mix a PW484-10 (DC) with a PW484-50 (AC) in the same power nest?
No. Power supply nests must use modules of the same input type. The PW484-10 requires a 24V DC backplane and cannot be paired with AC-input units.

What does the "-10" suffix indicate?
The "-10" identifies the module as the 24V DC input variant, differentiating it from AC-input versions like the -50 or -11 models.
