AFV10D-S41451 | Yokogawa CENTUM VP Duplexed Field Control Unit

Product Overview

The Yokogawa AFV10D-S41451 acts as the central intelligence hub for the CENTUM VP automation platform. This Duplexed Field Control Unit (FCU) manages high-speed data exchange across Vnet/IP networks while coordinating complex FIO module operations. It utilizes the LFS1500 control function to execute precise process logic. We provide this unit as 100% Brand New and Original, ensuring your facility utilizes the latest factory-certified hardware for mission-critical stability.

Technical Specifications

The AFV10D-S41451 optimizes processing power within a rack-mount form factor:

• Control Architecture: Duplexed (Dual-CPU) for automatic failover

• Network Interface: Vnet/IP (Dual-redundant)

• I/O Support: FIO (Field network I/O) series compatibility

• Control Function: LFS1500 specialized for Vnet/IP and FIO

• Operating Voltage: 24 V DC

• Mounting Type: 19-inch Rack Mountable

• Power Redundancy: Dual-redundant power modules included

Engineering Advantages

The AFV10D-S41451 resolves critical infrastructure challenges in process-heavy industries:

• Eliminate Process Upsets: The duplexed CPU architecture synchronizes data between the active and standby processors in real-time. If the primary unit fails, the standby takes control within milliseconds, preventing plant shutdowns or safety incidents.

• Low-Voltage Integration: The 24 V DC power configuration enables direct integration into standard industrial DC bus systems. This reduces the heat load and hardware footprint typically required for AC-to-DC conversion within the control cabinet.

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

• High-Density Rack Efficiency: The 19-inch rack-mountable design allows for high-density installation in standard enclosures. This compact layout maximizes cabinet space while the FIO interface allows for rapid expansion of local or remote I/O points.

FAQs

• Does this unit include the 24V DC power cables?

  The unit features dedicated terminals for 24V DC input. You must provide high-quality industrial-grade power cabling that meets the current draw requirements specified in the Yokogawa hardware manual.

• Is the LFS1500 control function pre-installed?

  The AFV10D-S41451 hardware supports the LFS1500 function. You configure and activate the specific control logic through the CENTUM VP engineering software to match your plant's operational needs.

• How does the unit handle power supply redundancy?

  The unit contains two separate power supply modules. It draws current from both simultaneously or switches to the healthy module if one input fails, ensuring the FCU logic never loses power.

• Can I mount this unit in a non-Yokogawa 19-inch rack?

  Yes. The AFV10D-S41451 follows standard EIA 19-inch dimensions. However, you must ensure the rack provides adequate natural convection and supports the structural weight of the duplexed unit.
