Product Description

The PW484-51 is a high-performance DC-to-DC power supply module specifically engineered for the Yokogawa CENTUM VP distributed control system. Unlike its AC-input counterparts, the PW484-51 is designed for facilities utilizing a centralized 24V DC power plant. This module provides critical voltage regulation required for Field Control Units (FCU) and FIO node units, ensuring sensitive logic circuits receive clean, stable power even in electrically noisy industrial environments.

Designed for high-availability architectures, the PW484-51 supports dual-redundant configurations. By installing two identical units within a compatible baseplate, the system can seamlessly transition power loads if one module fails, preventing costly process downtime. Its robust mechanical build and specialized interface connectors make it a standard choice for mission-critical oil, gas, and chemical processing applications.

Technical FAQ

Can I mix a PW484-51 with a PW481 or PW482 in the same rack?
No. For redundancy stability and electrical balance, it is strongly recommended to use two identical PW484-51 units in the same power supply nest.

What happens if the input voltage exceeds 26.4V DC?
The PW484-51 is rated for 24V DC ±10%. Operating above this range may trigger internal protection circuits or cause thermal stress to the module.
