Product Introduction

The YOKOGAWA YCB301-C100 is a 1-meter ESB bus cable designed for CENTUM VP distributed control system networks. It supports multiple CENTUM VP network types including V network, ER bus, ESB bus, and RIO bus, providing reliable data transmission between control stations, field control units, and communication nodes.

This cable is commonly used during DCS installation, expansion, or maintenance when replacing damaged or undersized bus cables. Having the correct length on hand avoids field cable routing issues and ensures proper connector strain relief within the cabinet. This unit is supplied as new original or new surplus, depending on stock availability.

 

QA & Testing SOP

Each unit is inspected before dispatch:

• Visual inspection: Check cable jacket for cuts, abrasions, kinks, or heat damage. Inspect connector housings for cracks or deformation.
• Connector inspection: Verify connector pins are straight, clean, and free of oxidation. Check locking mechanism integrity.
• Model verification: Confirm YOKOGAWA branding, model code YCB301-C100, and length marking on the cable or packaging.
• Continuity test: Verify pin-to-pin continuity and absence of short circuits across all conductors.
• Insulation test: Check insulation resistance between conductors to confirm no internal damage.
• Packaging: Packed with protective wrapping to prevent connector damage during transit.

 

Installation Pitfalls & Guide

❗ Match the cable length to the actual routing distance. The -C100 suffix means 1 meter. Using a cable that is too short creates tension on connectors; using one that is too long can cause clutter and signal integrity issues in tight cabinets.

❗ Do not substitute with generic cables. CENTUM VP bus cables use proprietary connectors and pinouts. Standard Ethernet or serial cables are not compatible.

❗ Avoid sharp bends and excessive tension. Bus cables should maintain a minimum bend radius to prevent internal conductor damage.

❗ Power down or follow hot-swap procedures. Depending on the network segment, replacing a bus cable may require taking the node offline. Follow site DCS maintenance procedures.

Replacement steps:

1. Pre-install: Record the existing cable routing, connector orientation, and node positions. Photograph the connections before removal.
2. Removal: Release connector latches and withdraw the cable gently. Do not pull on the cable body.
3. Install: Route the new cable along the same path, connect to the correct ports, and verify latch engagement.
4. Commissioning: Power up the nodes and confirm network communication status via CENTUM VP diagnostics.

 

Technical FAQ

Is pricing flexible for multiple units? Yes. Price depends on condition, quantity, and lead time. New original and new surplus stock are quoted separately. Send your quantity and we can provide a project-level quote.

What warranty is included? Standard warranty is 12 months from shipment for functional defects. This covers pre-shipment or manufacturing failures, not damage from incorrect installation, physical abuse, or environmental misuse.

What other lengths are available in the YCB301 series? The YCB301 series includes multiple length options such as 20 cm, 1 m (-C100), 2 m, 3 m, 4 m, and 8 m. Confirm the exact suffix needed for your installation.

Can YCB301-C100 be used for all CENTUM VP networks? Yes. The YCB301 series supports V network, ER bus, ESB bus, and RIO bus connections within CENTUM VP systems.

What information do you need to confirm compatibility? A photo of the existing cable label, the connected node models, and the required cable length are the most helpful. If available, share the cabinet wiring diagram or network topology.
