Yokogawa AFV30S-S41151 Field Control Unit | CENTUM VP

Product Overview

The Yokogawa AFV30S-S41151 acts as the central intelligence hub for the CENTUM VP distributed control system. This Field Control Unit (FCU) manages complex process control tasks, executing the LFS1700 control function set to coordinate high-speed data exchange between field instruments and the operator interface. We supply this unit as 100% Brand New and Original, providing a factory-fresh solution for facilities requiring high-speed Vnet/IP communication and FIO expansion capabilities.

Part Number Breakdown: AFV30S-S41151

Yokogawa utilizes a structured suffix system to define the redundancy and power specifications for the AFV30S series:

Technical Specifications

The AFV30S-S41151 provides high-density processing power in a standardized rack-mount format:

• Control Function: LFS1700 (Control Function for Field Control Station)

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

• I/O Interface: Supports FIO (Field network I/O) modules

• Power Supply: 100-120 V AC, 50/60 Hz (Dual-redundant configuration)

• Mounting: 19-inch rack mountable

• Redundancy: Supports redundant power and redundant network paths

• CPU Configuration: Single CPU architecture

Engineering Advantages

The AFV30S-S41151 provides specific technical solutions for large-scale industrial automation:

• High-Speed Network Redundancy: By utilizing dual-redundant Vnet/IP, the unit maintains continuous communication even if a network cable or switch fails. This prevents loss of visibility on the HMI (Human Machine Interface) during critical process phases.

• Continuous Power Availability: The dual-redundant power supply configuration allows the unit to draw power from two independent sources. If one supply fails, the second module assumes the full load instantly, eliminating the risk of a controller reset.

• Streamlined Rack Integration: The 19-inch rack-mountable design fits into standard industrial enclosures. This layout optimizes cabinet space and simplifies the cooling path for natural convection within the control room.

• Robust FIO Compatibility: The unit interfaces directly with FIO modules, allowing engineers to scale I/O points rapidly. This modularity enables easy expansion of the DCS without replacing the core control unit.

FAQs

• What is the difference between AFV30S and AFV30D?

  The AFV30S features a single CPU architecture, while the AFV30D provides a duplexed (redundant) CPU set. Choose the AFV30S-S41151 for applications where network and power redundancy are required, but CPU-level redundancy is not a mandatory requirement for the process loop.

• Does this unit support 220V AC power?

  No. This specific model (suffix code ending in '1') targets 100-120V AC environments. For 220-240V AC installations, you must select the corresponding power suffix (typically code '2').

• Can I hot-swap the power supply modules in this unit?

  Yes. The AFV30S-S41151 supports hot-swapping for its redundant power modules. You can replace a faulty power unit while the CPU remains operational, ensuring zero downtime for your control logic.

• Is the LFS1700 control function license included?

  This hardware supports the LFS1700 control functions; however, you must ensure your CENTUM VP software project includes the appropriate software licenses to activate and engineer the control logic.
