Yokogawa AFV30D-A41252 Duplexed Field Control Unit
Product Introduction
The AFV30D-A41252 is a duplexed Field Control Unit (FCU) engineered for Yokogawa’s CENTUM® VP and CENTUM® CS 3000 distributed control systems. It features dual-redundant CPUs, power modules, and network interfaces to deliver continuous, fault-tolerant control in the most demanding industrial environments. With the embedded LFS1550 control function, the AFV30D-A41252 executes complex logic and sequential operations for field I/O modules, enabling rapid, deterministic control of valves, motors, and other field devices.
Built for 19-inch rack installation, the AFV30D-A41252 combines a robust metal enclosure with vibration-resistant mounting, ensuring long-term reliability in petrochemical, power, and water treatment facilities.
Key Applications
Continuous control of reactors, distillation columns, and separators in chemical and petrochemical plants.
Boiler, turbine, and auxiliary system management in thermal and combined-cycle power plants.
Pump station sequencing, valve interlocks, and chemical dosing in water and wastewater treatment.
Motion control and drive interlocking in pulp & paper production lines.
Critical batch control in pharmaceutical and specialty chemical manufacturing.
