AFV30D-A41251 | Yokogawa Duplexed Field Control Unit | CENTUM VP

Product Overview

The Yokogawa AFV30D-A41251 serves as the high-availability processing core for the CENTUM VP Distributed Control System (DCS). This Duplexed Field Control Unit (FCU) executes critical process control logic and manages high-speed data synchronization across Vnet/IP and FIO subsystems. By integrating dual-redundant processor and power modules, the AFV30D-A41251 eliminates single points of failure, ensuring uninterrupted plant operation. We supply this unit as 100% Brand New and Original, providing factory-certified hardware for mission-critical automation environments.

Part Number Breakdown: AFV30D-A41251

Yokogawa utilizes a structured suffix system to define the functional capabilities and power requirements of the AFV30D series:

Technical Specifications

The AFV30D-A41251 incorporates industrial-grade components to handle large-scale I/O throughput:

• Control Function: LFS1500 (Optimized for Vnet/IP and FIO systems)

• Architecture: Duplexed CPU for instantaneous failover

• Network Interface: Dual-redundant Vnet/IP (1 Gbps high-speed bus)

• Power Input: 220 V to 240 V AC, 50/60 Hz

• Mounting: Standard 19-inch rack mountable

• I/O Capacity: Supports high-density FIO module integration

• Redundancy: CPU, Power, and Communication redundancy paths

Engineering Advantages

The AFV30D-A41251 resolves complex industrial infrastructure challenges through superior hardware engineering:

• Instantaneous Hardware Failover: The duplexed CPU architecture synchronizes data in real-time. If the active processor detects a fault, the standby unit assumes control within milliseconds. This prevents process bumps and ensures safety in volatile chemical or power generation environments.

• Network Fault Tolerance: Dual-redundant Vnet/IP ports maintain continuous communication even if a network cable sustains physical damage or a switch port fails. This ensures operators never lose visibility of field variables during a network disturbance.

• Streamlined Rack Integration: The unit follows standard 19-inch dimensions, fitting perfectly into existing marshaling cabinets. This allows engineers to upgrade control capacity without requiring custom metalwork or extensive cabinet modifications.

• High-Voltage Grid Compatibility: Specifically configured for 220–240 V AC (Suffix '2'), the internal power modules filter line noise and protect the logic circuits from voltage transients common in heavy industrial grids.

FAQs

• Does the AFV30D-A41251 include the LFS1500 software license?

  The hardware includes the LFS1500 control function capabilities. However, you must verify your CENTUM VP system license permits the addition of a new Field Control Station (FCS) within your specific project project file.

• How do you guarantee the quality of this unit?

  We source only 100% Brand New and Original Yokogawa hardware. Each unit arrives in its original factory packaging with a clean serial number history, ensuring full compatibility with Yokogawa's R6.01+ engineering environments.

• Can I replace an older AFV30S (Single) model with this AFV30D (Duplexed)?

  Yes, you can upgrade to the duplexed version to enhance reliability. Ensure your rack power distribution handles the redundant power module load and that your software configuration supports duplexed CPU operation.

• What maintenance does the unit require?

  This FCU utilizes natural convection for cooling. Ensure you maintain the specified 19-inch rack clearances to allow heat dissipation. Additionally, check the internal battery status periodically to ensure RAM data protection during power outages.
