Yokogawa PFCD-S5520/2-TE Field Control Station

Product Description

The Yokogawa PFCD‑S5520/2‑TE is a high-reliability duplexed Field Control Station (FCS) designed for CENTUM VP and CENTUM CS 3000 distributed control systems. It provides a robust platform for process control, combining dual-redundant CPUs, communication interfaces, and power supplies within a single rack-mounted enclosure.

This FCS is engineered for continuous operation in critical industrial environments, ensuring system availability even under hardware faults. Its modular design allows easy integration with field networks and higher-level control systems.
