Yokogawa VF702 Vnet Control Bus Interface Card

Product Overview

The Yokogawa VF702 functions as a high-performance Control Bus Interface Card designed for seamless communication within the Yokogawa DCS ecosystem. It manages high-speed data exchange between human interface stations and control stations across the Vnet network. We provide this hardware as 100% Brand New and Original, ensuring full signal integrity and factory-standard throughput for your industrial automation network.

Technical Specifications

The VF702 utilizes the 10BASE-2 standard to facilitate robust bus-topology networking in demanding control environments.

Engineering Advantages

• Optimized Bus Communication: The VF702 employs 10BASE-2 (Thinnet) technology, allowing for reliable data transmission over coaxial cabling. This setup effectively minimizes electromagnetic interference (EMI) in electrically noisy industrial environments, maintaining stable DCS network uptime.

• Simplified Integration: The card utilizes a standard BNC interface, which simplifies field connections. By pairing the VF702 with the YCB146 coaxial cable and T-type connectors, engineers can quickly expand or modify the control bus without complex rewiring.

• Compact Form Factor: With a thickness of only 2.5 cm, the VF702 maximizes slot density within the control station. This compact design allows for more intensive hardware configurations in space-constrained server rooms or cabinets.

• Plug-and-Play Compatibility: Engineered specifically for the Yokogawa system architecture, the VF702 requires no extensive software modification for recognition. This ensures rapid deployment during system upgrades or emergency hardware replacements.

FAQs

What cable and connector types does the VF702 require?

The VF702 requires a high-quality coaxial cable, specifically the Model YCB146, along with a T-type connector for bus integration. It features a standard BNC interface to ensure a secure, twist-lock connection.

Does the VF702 support redundant network configurations?

Yes. In most Yokogawa DCS architectures, you install two VF702 cards to provide dual-redundancy for the Control Bus. This configuration ensures that communication continues uninterrupted if one card or path fails.

Can I install the VF702 while the system is under power?

While many modern modules allow for hot-swapping, we recommend following the specific hardware installation manual for your specific station model (e.g., AFV or AV5). Always verify the "Hot Swap" status of the specific slot to prevent signal spikes on the control bus.

Is this network card a refurbished unit?

Absolutely not. We supply only 100% Brand New Yokogawa hardware. Each VF702 arrives in its original factory anti-static packaging, complete with the official manufacturer serial number to guarantee authenticity and long-term reliability.
