Product Details

The Yokogawa AFV30D-A41452 S2 serves as the core Field Control Unit (FCU) for the CENTUM VP and CS 3000 Distributed Control Systems (DCS). This high-performance backplane module executes complex control strategies, manages distributed I/O modules, and facilitates high-speed data exchange with operator stations. We provide this unit as 100% brand new and original in factory packing, ensuring the highest level of computational reliability for mission-critical process automation.

Product Overview

The AFV30D-A41452 acts as the "brain" of the field control station. It integrates a high-performance CPU with dedicated memory to handle real-time control logic, PID loops, and sequence control. By utilizing a dual-redundant architecture, the AFV30D-A41452 maintains continuous plant operation even during a hardware or power failure. It connects directly to the Vnet/IP network for supervisory communication and utilizes the ESB/ER bus to manage local and remote I/O nodes, making it essential for large-scale refineries, power plants, and chemical facilities.

Engineering Advantages

Duplexed Fault Tolerance: The "D" designation signifies a duplexed configuration. This allows for seamless, bumpless transfer between the active and standby processors in less than a millisecond, preventing process upsets during hardware transitions.
High-Speed Vnet/IP Integration: The unit supports 1 Gbps Vnet/IP communication. This provides massive bandwidth for alarm management and real-time data polling, ensuring the Human Interface Station (HIS) always reflects the current field state without latency.
Scalable I/O Management: The AFV30D-A41452 manages extensive I/O counts through the ESB and ER bus nodes. This flexibility allows engineers to distribute I/O modules across vast plant distances while maintaining centralized control.
Robust Memory Protection: The onboard memory includes Error Correction Code (ECC) to prevent bit-flips and data corruption. This hardware-level protection ensures that complex control algorithms execute correctly 24/7.
Rugged Rack-Mount Design: The 19-inch modular rack design fits standard industrial cabinets. The chassis provides excellent thermal dissipation and EMI shielding, protecting the internal electronics from the harsh electrical noise found in heavy industrial environments.

FAQs

What does the "Duplexed" (D) function provide in the AFV30D?

The Duplexed function means the unit contains two independent processor circuits. If the primary processor detects an internal fault, the standby processor takes over control instantaneously. This ensures your plant never loses control visibility or logic execution.

Is the AFV30D-A41452 compatible with 220V power?

No. The "-4" in the part number specifies a 100-120 V AC power requirement. If your facility uses 220-240 V AC, you must use the -2 power variant to avoid damaging the internal power supply modules.

How does this unit connect to the Vnet/IP network?

The AFV30D-A41452 typically connects via standard RJ-45 Ethernet ports to an industrial L2 switch. For redundant Vnet/IP networks, you must connect both ports to separate switches to maintain path redundancy.

Can I replace an S1 unit with this S2 Style module?

Yes. The Style S2 revision is generally backward compatible with Style S1 systems in terms of form factor and basic functionality. However, always verify that your current CENTUM VP software version supports the S2 hardware revision to ensure all diagnostic features are available.
