Yokogawa AFV30D-S41252 Duplexed Field Control Unit
Product Introduction
The AFV30D-S41252 is a robust duplexed Field Control Unit (FCU) designed for seamless integration with Yokogawa’s CENTUM® VP distributed control system. Equipped with the LFS1550 control function, it executes complex sequence logic and provides deterministic field I/O management. Dual-redundant CPUs, power supplies, and network interfaces ensure continuous operation even in the event of a component failure. The unit’s steel chassis and vibration-dampening rack mounts guarantee stability and long service life in harsh industrial environments.
Key Applications
Continuous control of refining processes, including fractionation and reactor temperature regulation.
High-speed sequencing for turbine governors, boiler feedwater systems, and auxiliary plant equipment.
Automated pump station coordination, chemical dosing, and valve interlocks in water and wastewater treatment.
Motion control and safety interlocks in pulp and paper lines, including dryer drives and headbox systems.
Batch recipe execution, data logging, and alarm management in pharmaceutical and specialty chemical production.
Brand Overview
Yokogawa stands as a pioneer in industrial automation since 1915. With core strengths in process control, test and measurement, and information solutions, Yokogawa supports critical industries worldwide through rigorous quality standards, innovative R&D, and comprehensive lifecycle services.
Product Advantages
-
Fault-Tolerant Architecture: Redundant CPUs, power modules, and Vnet/IP interfaces with instantaneous switchover protect operations from single-point failures.
-
Expanded I/O Capacity: LFS1550 supports up to 32 field I/O nodes, enabling flexible scaling across large process areas.
-
Rack-Optimized Footprint: At just 4U high and 482.6 mm deep, the unit conserves valuable control room real estate without compromising functionality.
-
High-Speed Communications: Dual-redundant Vnet/IP ports deliver deterministic data exchange and support oversubscription topologies.
-
Enhanced Maintainability: Front-panel LEDs, two dry-contact alarm outputs, and SNMP trap capability enable rapid fault detection and preventive maintenance.
