Présentation du produit
The Yokogawa AFV30D-S41251 S2 Duplexed Field Control Unité (FCU) is a high-reliability control platform developed for Yokogawa’s CENTUM VP distributed control system. This model builds upon the proven AFV30D architecture with S2 enhancements, surfering stronger redundancy, improved processing capabilities, and advanced fault tolerance.
The FCU is specifically designed for large-scale, mission-critical process industries where downtime and process interruptions are unacceptable. With duplexed CPUs, redundant power supplies, and dual communication paths, the AFV30D-S41251 S2 ensures continuous operation even if critical hardware fails. Its hot-swappable design allows maintenance while the system is live, minimizing plant downtime.
