Yokogawa PW484-50 Suffix -50 CENTUM VP 24V DC Input Power Supply Module

The PW484-50 (Model: PW484-50) is a high-reliability DC-to-DC power supply module specifically engineered for Yokogawa’s CENTUM VP and CS 3000 Distributed Control Systems (DCS). Unlike standard AC units, the PW484-50 (Part Number: PW484-50) is designed to accept a 24 V DC input, making it ideal for plants utilizing centralized DC battery systems or solar-backed power infrastructures.

As a "Basic Type" with the -50 suffix code, this module is built for standard industrial environments without specific explosion protection requirements. It features an extended operating temperature range, maintaining stable performance from -20 °C to 70 °C. To guarantee maximum system uptime, the PW484-50 (Model: PW484-50) supports 1:1 dual-redundant operation. In this configuration, two modules share the load across the system backplane, ensuring that control processors and I/O modules remain energized even if one power source or module fails.
