Description

Brief Product Description

The Yokogawa AFV30D S2 is a high-performance, duplexed field control unit designed for the CENTUM VP distributed control system.¹ It provides redundant processing capabilities to ensure continuous, fault-tolerant operation for safety-critical industrial automation and large-scale process management.

​Product Description

Redundant Processing for Process Continuity

The Yokogawa AFV30D S2 serves as the primary intelligence node within the CENTUM VP architecture. This duplexed field control unit (FCU) utilizes dual-redundant processors to eliminate single points of failure.² If the active processor detects an internal fault, the standby unit assumes control instantaneously without interrupting the process. This “bumpless” transfer is essential for complex industries where unplanned downtime results in significant financial loss or safety risks. By executing control logic and managing I/O communication simultaneously, the AFV30D S2 maintains stable plant operations around the clock.

Optimized Design for Industrial Integration

Yokogawa engineered the AFV30D S2 with a focus on spatial efficiency and environmental resilience. The unit features a 19-inch rack-mountable form factor, allowing for straightforward installation in standard control cabinets.³ Despite its compact size, the hardware remains robust enough to withstand the vibrations and thermal fluctuations typical of industrial environments. Furthermore, the S2 version includes enhanced circuitry protection, such as optional conformal coating, to resist corrosive atmospheric elements. These characteristics make it a preferred choice for petrochemical plants, refineries, and power generation facilities.

Connectivity and Global Compliance

Communication versatility distinguishes the AFV30D S2 from standard controllers. It supports the Vnet/IP high-speed control network, ensuring rapid data exchange between the FCU and Human Interface Stations (HIS). Moreover, the unit facilitates the integration of various fieldbus protocols, enabling comprehensive visibility into field instrumentation.⁴ To support global deployment, the unit carries UL, CSA, and CE certifications, adhering to rigorous international safety and electromagnetic compatibility standards. This compliance ensures that the AFV30D S2 fits seamlessly into regulated industries while providing a secure and reliable control environment.
