Product Description

The PW484-10 is a high-performance DC-input power supply module engineered for the Yokogawa CENTUM VP Integrated Production Control System. Designed specifically for 24 V DC power architectures, it is ideal for plants utilizing centralized DC power systems or battery-backed supplies. The module converts external DC power into regulated internal voltages required by Field Control Units (FCUs) and I/O expansion nodes, ensuring uninterrupted operation in mission-critical automation environments.

Technical Specifications

Key Operational Advantages

The PW484-10 is optimized for high-availability DC-powered control systems. In redundant installations, paired modules operate in load-sharing mode; if one unit fails, the remaining module instantly assumes full load without affecting controller logic or field communications. The “-10” revision provides effective electrical isolation between the external DC supply and sensitive internal electronics, minimizing noise propagation and enhancing overall system stability within the FIO architecture.

Technical FAQ

Q: Can the PW484-10 be used in an AC-powered control cabinet?
A: No. The PW484-10 is strictly a 24 V DC input module. For AC-powered systems (100–240 V AC), PW481 or PW482 series power modules should be used.

Q: Is hot-swapping supported?
A: Yes. When installed in dual-redundant (“D” suffix) FCUs, the PW484-10 supports hot-swap replacement, enabling maintenance without process interruption.
