製品紹介
The Yokogawa AFV30D-S41251 S2 Duplexed Field Control ユニット (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, /fering 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.
