Yokogawa AFV30D-S41262 Duplexed Field Control Unit

Product Introduction

The Yokogawa AFV30D-S41262 Duplexed Field Control Unit (FCU) is a high-performance controller used in the CENTUM VP distributed control system. This unit is engineered for mission-critical applications where uninterrupted plant operation is essential. Designed with full duplex redundancy, it provides failover protection for CPUs, power supply, and network communication.

The AFV30D-S41262 offers enhanced data processing capabilities and expanded memory compared with earlier FCU variants, supporting large I/O loads and high-speed communication across industrial environments. Its hot-swappable modular design makes maintenance seamless, and its built-in diagnostics provide predictive monitoring to reduce downtime. With certification for hazardous areas, it is suitable for diverse sectors such as petrochemical, oil & gas, power generation, pharmaceuticals, and water treatment.
