Yokogawa AFV30D-A41152 Duplexed Field Control Unit

Product Description

The Yokogawa AFV30D-A41152 is a duplex redundant field control unit (FCU) for the Yokogawa CENTUM VP DCS system. It serves as the core controller of the Field Control Station (FCS), equipped with dual Vnet/IP communication and dual power supply design. It executes real-time process control logic, collects field I/O signals and communicates with the operation and monitoring station. With hot standby redundancy, it supports uninterrupted switching to avoid production shutdown caused by single point failure, widely used as critical spare parts for process plant DCS maintenance and retrofit.

Product Functions

• Run continuous PID, sequence control and interlock logic for industrial process loops
• Real-time data acquisition and output control for analog and digital I/O modules
• Dual redundant Vnet/IP communication for data exchange with HMI and other FCS stations
• Hot standby redundant operation, seamless master-slave switching without process interruption
• Integrated fault diagnosis, self-test and fault status upload to the monitoring system
• Support FIO field I/O modules and 19-inch standard rack mounting

Application Scenarios

• Petrochemical, refining and natural gas process control DCS systems
• Thermal power plant, boiler and turbine distributed control systems
• Chemical, pharmaceutical and water treatment continuous production facilities
• Pipeline, offshore platform and large-scale industrial process automation
• Spare replacement and repair of existing Yokogawa CENTUM VP racks
