Product Description
The YOKOGAWA AFV30D-A41251 Duplexed Field Control Unit represents advanced process automation technology designed for high-availability industrial control systems. This dual-redundant FCU ensures continuous operation in mission-critical environments where downtime is not an option.
Technical Architecture
Built on YOKOGAWA's proven CENTUM VP platform, the AFV30D-A41251 features duplexed processing architecture that provides seamless failover capability. The unit supports both Vnet/IP Ethernet-based control networks and traditional FIO (Field Input/Output) interfaces, enabling flexible integration with legacy and modern automation infrastructure. Dual processors operate in hot-standby configuration, automatically switching control authority within milliseconds upon detecting primary controller anomalies.
Application Scenarios
Ideal for continuous process industries including oil & gas refining, petrochemical production, power generation, pharmaceutical manufacturing, and pulp & paper operations. The duplexed architecture eliminates single points of failure in critical control loops managing temperature, pressure, flow, and level regulation. Particularly suited for Safety Instrumented Systems (SIS) integration where IEC 61511 compliance and high integrity protection layers are required.
Integration & Connectivity
The AFV30D-A41251 seamlessly integrates with YOKOGAWA's comprehensive automation ecosystem including HIS (Human Interface Station), EWS (Engineering Workstation), and various field devices through FOUNDATION Fieldbus, HART, and conventional 4-20mA analog signals. Vnet/IP connectivity enables distributed control architecture across multiple control rooms and remote facilities with deterministic real-time performance.
Reliability Solutions
Diagnostic capabilities include continuous self-monitoring, predictive maintenance alerts, and comprehensive event logging. The unit's modular design facilitates online replacement of failed components without process interruption. Environmental hardening supports operation in industrial temperature ranges with enhanced EMI/RFI immunity for harsh electromagnetic environments.
