Description
The Yokogawa YCB301-C100 is a 100-meter, high-performance ESB (Extended System Bus) processor bus cable designed for the CENTUM VP and ProSafe-RS control architectures. This specialized communication link connects safety control units, safety node units, or field control stations, facilitating high-speed, deterministic data transmission across the main control backplane network.

Installation and System Integration Notes
Are you running this 100-meter bus cable through high-voltage cable trays? Because the YCB301-C100 carries high-speed master-slave clock and control signals between nodes, routing it parallel to heavy motor-drive power lines will induce electromagnetic noise and trigger frame-check sequence (FCS) communication errors. In field deployments of ProSafe-RS systems, we found that isolating the ESB bus lines inside dedicated grounded steel conduits or separate communication channels keeps transmission jitter to zero.
Well, technically it supports a 100-meter straight run, but don’t underestimate the physical strain on the connectors during vertical routing; you must provide strain-relief clamping at both ends of the cabinet entry point. When inserting the heavy rectangular connectors into the controller’s bus card, tighten the retention thumbscrews evenly on both sides—unbalanced tightening can misalign the internal pins, leading to intermittent node dropouts.
Verify your layout topology limits and bus termination requirements with the official Yokogawa Hardware Manual (TI 33J01A10-01EN) prior to pulling the cable through conduits.
Global Trade & Shipping Logistics
Shipping bulk, pre-terminated system bus cabling internationally requires exact regulatory and physical handling considerations to ensure the assembly arrives without internal structural damage.
- HS Code (Harmonized System): 85444220 (Insulated electric conductors for a voltage not exceeding 80 V, fitted with connectors)
- ECCN (Export Control Classification Number): EAR99 (No specific export license required for most commercial destinations, subject to standard restricted-party screening)
- Incoterms Options: Ex Works (EXW), Free Carrier (FCA), or Cost, Insurance, and Freight (CIF) to your designated destination port.
- Customs Documentation: Every international shipment includes an itemized Commercial Invoice, a detailed Packing List specifying spool dimensions/gross weights, and a Certificate of Origin where required by regional free trade agreements.
- Transit Packaging: Wound securely on a protective inner spool, sealed inside heavy moisture-barrier plastic wrap, and shipped within a reinforced wooden crate or extra-strength corrugated carton to prevent crushing or pinching during international transit sorting.
For urgent expansion projects or emergency system maintenance, we utilize priority air freight (DHL Express, FedEx International Priority, or UPS Worldwide Saver) to minimize operational downtime. Standard customs processing usually clears within 24 to 48 hours provided the importer of record documentation is complete.
Frequently Asked Questions
- Can the YCB301-C100 cable be cut and spliced to shorter lengths in the field?Absolutely not. The YCB301 series cables are factory-assembled, impedance-matched, and pre-tested with molded connectors. Cutting the cable or attempting manual pin splicing in the field will alter the high-frequency transmission characteristics, causing severe signal reflections and stopping the ESB bus from initializing.
- What does the “-C100” portion of the part number represent?The suffix code explicitly identifies the length configuration of the assembly. The “C” indicates the length unit is measured in meters, and the “100” establishes the total end-to-end span as exactly 100 meters. Other length variants (e.g., -C010 for 10 meters or -C050 for 50 meters) follow the same syntax rules.
- Is an external terminator required when using this 100-meter cable?The need for terminators depends on the specific interface modules installed in your node. Generally, when connecting an ESB Bus Master Module to an ESB Bus Interface Module over a long distance, the final module on the physical bus topology must have an active termination block (such as the YCB301 matched termination caps or internal card jumpers set) to prevent signal echo.
