Product Details

Product Overview

The Yokogawa RB301 serves as a high-performance RIO (Remote I/O) Bus Interface Master Card designed for the Yokogawa DCS architecture. It establishes a high-speed communication backbone between the primary control station and remote I/O units, ensuring real-time data synchronization across the plant floor. We supply this hardware as 100% Brand New and Original, providing the critical link required to maintain the timing and integrity of your distributed control network.

Engineering Advantages

  • High-Density Device Integration: A single RB301 master card manages up to 31 RIO devices per bus segment. This high capacity reduces the number of physical interface cards required in the control station, optimizing rack space and lowering overall hardware costs.

  • Deterministic Data Throughput: The 10 Mbps bus speed provides the deterministic communication necessary for critical control loops. It ensures that process variables reach the CPU and control commands reach the field actuators within strict timing windows, preventing process instability.

  • Robust Physical Interface: The DB-37 connector provides a secure, industrial-grade mechanical connection. This multi-pin interface handles high-speed differential signals while resisting the mechanical stresses and vibrations common in industrial control cabinets.

  • Wide Thermal Tolerance: Engineered for longevity, the RB301 operates across a broad temperature range of -20°C to 60°C. This resilience allows for installation in varied environments, from climate-controlled server rooms to ventilated field enclosures.

FAQs

How many RIO devices can I connect to one RB301 card?

The RB301 supports up to 31 Yokogawa RIO bus devices per segment. Always ensure your total bus length and termination settings comply with Yokogawa's RIO networking guidelines to maintain 10 Mbps signal integrity.

Does the RB301 support redundancy?

Yes. In mission-critical DCS configurations, you should install a pair of RB301 cards to provide dual-redundant communication paths. This ensures the control bus remains active even if one master card or cable segment fails.

Can I install the RB301 in a standard PC?

While the RB301 uses a half-length PCI form factor, it requires specific Yokogawa drivers and a compatible CENTUM station environment (such as a Human Interface Station or Control Station) for proper operation. It is not intended for standard consumer PC applications.

Is this a refurbished or pull-out unit?

No. We offer only 100% Brand New Yokogawa RB301 cards. Every unit ships in its original anti-static factory packaging with an intact manufacturer serial number to guarantee authenticity and full factory-rated performance.
