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
Understanding Marshalling Cabinets in Industrial Control Systems Architecture
Industrial control system deployments rely on structured signal distribution to bridge field instrumentation with central processing hardware. A marshalling cabinet serves as the vital intermediate connection point between heavy field home-run multi-pair cables and delicate input/output (I/O) modules housed inside Programmable Logic Controller (PLC) or Distributed Control System (DCS) enclosures. By segregating field cable terminations from control hardware, engineers maintain system flexibility, safeguard controller components, and streamline commissioning workflows.
FAT vs SAT in Industrial Control Systems: Key Differences and Execution Guide
Industrial control system deployment relies on strict verification protocols to guarantee operational safety, system stability, and regulatory compliance. Commissioning complex Programmable Logic Controller (PLC) racks, Distributed Control Systems (DCS), and Safety Instrumented Systems (SIS) requires two critical milestones: the Factory Acceptance Test (FAT) and the Site Acceptance Test (SAT). Both procedures validate that system automation meets design specifications, but they occur at different stages of project execution and target distinct operational risks.
Hub vs Switch vs Router in Industrial Automation Architecture
Modern factory automation relies on reliable industrial networking infrastructure to exchange real-time field data across operational technology systems. Engineers often encounter networking hardware like hubs, switches, and routers when integrating Programmable Logic Controllers, Distributed Control Systems, and SCADA monitoring nodes. Although these devices share physical ports, they operate at different layers of the Open Systems Interconnection reference model and deliver distinct traffic management capabilities.
