Yokogawa AFS40D Duplexed Field Control وحدة

مقدمة المنتج

The Yokogawa AFS40D Duplexed Field Control وحدة is a state-من-the-art control processor used in Yokogawa’s CENTUM VP Distributed Control System (DCS). As a fully redundant (duplexed) FCU, the AFS40D is engineered for critical control processes requiring high availability and operational integrity. Equipped with dual CPUs, dual power supplies, and redundant communication interfaces, this وحدة ensures uninterrupted control even during hardware or system faults.

Designed for scalability and performance, the AFS40D supports advanced field networks like Vnet/IP, FOUNDATION Fieldbus, HART, and Modbus, and provides seamless integration into the broader CENTUM VP architecture. It is ideal for industries such as oil & gas, chemicals, utilities, pharmaceuticals, and power generation, where reliability, speed, and fault tolerance are essential.
