Yokogawa Duplicated Field Control Unit (FCU) | AFV30D-A41452

Product Overview

The Yokogawa AFV30D-A41452 is a high-performance, high-capacity Field Control Unit (FCU) designed for the CENTUM VP Distributed Control System (DCS). As an evolution of the AFV10 series, the AFV30D provides significantly greater processing power and memory, making it the primary choice for large-scale, complex industrial facilities. The "D" signifies its Duplicated (Duplexed) architecture, ensuring that control logic continues to execute without interruption even if a processor component fails. This specific model features G3-level corrosive resistance, essential for harsh industrial environments.

Condition: 100% Brand New and Original Factory Sealed.

Part Number Breakdown: AFV30D-A41452

Yokogawa uses a detailed suffix code to define the hardware capabilities and environmental ratings of the AFV30 series:

• AFV30D: Duplicated Field Control Unit (High-capacity for Vnet/IP and FIO).

• -A: Standard type hardware.

• 4: Dual-redundant 100-120 V AC Power Supply.

• 1: 19-inch Rack-mount type.

• 4: With Vnet/IP interface (Dual-redundant).

• 5: With G3 Corrosive Resistance (Conformal coating for $H_{2}S$, $SO_{2}$, and $Cl_{2}$ protection).

• 2: Updated hardware revision for enhanced CPU stability and thermal management.

Technical Specifications

The AFV30D-A41452 provides the massive processing power required for high-point-count industrial automation.

• Processor: High-speed RISC processor (advanced capacity over AFV10 series).

• Control Network: Vnet/IP (1 Gbps redundant Ethernet-based network).

• I/O Bus: FIO (Field Input/Output) bus for high-speed module communication.

• Environmental Protection: ISA Standard S71.04 Class G3.

• Memory Protection: Battery-backed RAM and non-volatile flash memory.

• Mounting: Standard 19-inch rack-mount.

• Redundancy: CPU, Power Supply, and Network modules are all dual-redundant.

Engineering Advantages

• Ultra-High Control Capacity: The AFV30D series is engineered to manage a significantly higher number of function blocks and sequence tables than previous generations. This allows a single control station to manage larger plant sections, reducing the total number of FCUs required and simplifying system architecture.

• G3-Rated Corrosive Resistance: The internal circuit boards are treated with a specialized conformal coating. This protection is critical for oil refineries, chemical plants, and wastewater facilities where aggressive atmospheric gases would otherwise cause copper and silver corrosion.

• Seamless Mission-Critical Redundancy: Featuring "Hot Standby" duplication, the AFV30D-A41452 synchronizes data between two CPU modules every scan cycle. If the primary unit fails, the secondary takes over in milliseconds, ensuring zero "bumps" in process control.

• Vnet/IP 1 Gbps Backbone: By utilizing a high-speed redundant Ethernet-based network, this controller can exchange massive amounts of process data with the HMI and other controllers with negligible latency.

• Online Hardware Maintenance: All redundant components, including the PW481 power supplies and CP471 processor modules, are hot-swappable. Maintenance teams can replace a failed component while the plant remains under active control, maximizing uptime.

FAQs

• How does the AFV30D differ from the AFV10D?

  The AFV30D offers roughly double the application capacity and significantly faster processing speeds. It is designed for larger, more complex control strategies that would overwhelm an AFV10D.

• Does this unit include the CPU modules?

  The AFV30D-A41452 defines the chassis, power supply, and environmental specs. While it is the housing for the CPU modules (typically CP471), those modules are often ordered as separate components depending on the specific system configuration.

• Can I use this unit in a 220V AC environment?

  No. The suffix "-4" indicates a 100-120 V AC power requirement. For 220-240 V AC environments, you would need the model with the "-2" suffix.

• What is the significance of the "2" at the end of the suffix?

  The "2" indicates a hardware revision. Yokogawa periodically updates internal components for better thermal efficiency or to address component obsolescence, ensuring the controller remains reliable throughout its 20+ year lifecycle.
