Product Details
Product Overview
The Yokogawa YCB301-C020 functions as the high-speed communication backbone for the CENTUM VP integrated control system. This ESB (Extended Serial Backplane) Bus Cable facilitates the critical connection between the Field Control Station (FCS) and its expansion I/O nodes. With a specialized 36-to-36 pin interface, it enables real-time, deterministic data exchange across the control network. We supply this unit as 100% Brand New, ensuring factory-spec signal integrity and mechanical durability for your mission-critical automation infrastructure.

Engineering Advantages
The YCB301-C020 optimizes system architecture through several technical features:
-
Minimal Latency for Adjacent Expansion: The short 20 cm length provides an ideal solution for side-by-side node expansion. It eliminates excess cable slack in the cabinet, reducing signal propagation delay and preventing cable clutter in high-density racks.
-
EMI/RFI Suppression: The cable incorporates heavy-duty industrial shielding. This design protects high-speed data packets from electromagnetic interference generated by adjacent power supplies or high-voltage switching gear within the control cabinet.
-
Vibration-Proof Locking Mechanism: The 36-pin connectors utilize mechanical fastening screws. These anchors prevent accidental disconnection in high-vibration industrial environments, ensuring continuous network uptime.
-
Engineered Impedance Matching: Yokogawa tunes the internal conductor impedance to match the ESB Bus interface precisely. This prevents signal reflection and data corruption, which often occur when using non-genuine or poorly terminated cables.
FAQs
Can I use the YCB301-C020 to connect to a remote I/O rack?
No. The C020 suffix indicates a 20 cm length, which engineers design specifically for connecting adjacent units within the same cabinet. For remote node expansion, you must select a longer YCB301 variant with a larger length suffix.
Does this cable support hot-swapping during operation?
While the CENTUM VP architecture offers redundancy, we recommend following standard Yokogawa safety protocols. Power down the expansion node before connecting or disconnecting the ESB Bus cable to prevent voltage spikes or communication errors on the live backplane.
Why is the shipping weight listed as 2 kg for a 20 cm cable?
To protect the high-density 36-pin connectors from damage during transit, we utilize heavy-duty protective packaging. This ensures the cable arrives with perfectly straight pins and intact shielding, ready for immediate installation.
Is this cable compatible with both the primary and redundant ESB Bus ports?
Yes. The YCB301-C020 serves both the "Bus 1" and "Bus 2" ports of the ESB interface. For a fully redundant configuration, we recommend purchasing two identical cables to ensure matched signal characteristics across both communication paths.

Tech & Buying Guide
Evolving SCADA System Architectures in Industrial Automation
A robust Supervisory Control and Data Acquisition (SCADA) system serves as the heartbeat of modern industrial operations. Understanding SCADA system architecture is vital for engineers designing efficient control systems. These architectures have evolved from isolated, monolithic structures to highly interconnected, networked ecosystems. Choosing the right design requires balancing data visibility, processing power, and long-term scalability requirements.
Choosing the Right Controller: PLC vs. Motion Controller in Industrial Automation
Selecting the optimal control architecture is a foundational decision in industrial automation. Engineers must frequently choose between a Programmable Logic Controller (PLC) and a dedicated Motion Controller. While both systems manage machinery, their underlying design philosophies differ significantly, impacting performance, scalability, and system integration.
Mastering PLC Power Supply Architectures and Operating Voltages
Selecting the correct operating voltage is a critical step in designing reliable industrial automation systems. Whether you are working with a compact PLC or a large-scale DCS, your power architecture dictates the system's longevity. In this guide, we explore the standard voltage ranges and power distribution strategies required to maintain stable factory automation operations.
