The YOKOGAWA YCB141-M015 (YCB141 Vnet Cable) serves as the primary YCB141-M015 communication cable utilized to execute deterministic data exchange across CENTUM and ProSafe control platforms.

Suffix Breakdown & Model Matrix

• YCB141: Base series identifier for 10BASE-2 coaxial Vnet communication cabling.
• M015: Suffix code designating a physical cable length of 15 meters.

Hardware Specifications

DCS Process Control Integration

The YCB141-M015 provides the physical transmission medium for the Vnet control bus, enabling real-time synchronization between distributed control nodes. The cable is manufactured to precise 10BASE-2 coaxial specifications, maintaining the characteristic impedance required to prevent signal reflection at 10 Mbps transmission speeds. Integrated factory-terminated BNC connectors ensure optimal contact resistance and mechanical robustness, providing a consistent signal path that minimizes packet error rates in environments requiring high network availability.

Frequently Asked Questions

Q: Does the 15-meter length affect the maximum allowable bus segment length?

A: Yes, the 15-meter segment contributes to the total cumulative length of the Vnet bus. Ensure the total segment length does not exceed the manufacturer-specified limits for 10BASE-2 coaxial segments to maintain network determinism.

Q: Can this cable be extended by coupling it with another YCB141 cable?

A: While physical extension is possible via BNC barrel connectors, each additional connection point introduces potential impedance discontinuities and insertion loss; direct continuous cable runs are preferred.

Field Installation Guidelines

1. Power down the communication bus prior to cable installation to prevent potential damage to the Vnet controller interfaces.
2. Route the 15-meter cable through dedicated signal cable trays, maintaining a minimum 15 cm clearance from power conductors.
3. Observe the cable's minimum bend radius to prevent internal dielectric compression, which can lead to signal attenuation.
4. Verify all BNC connections are firmly locked into the bulkhead ports, ensuring the outer shield maintains a continuous path to the chassis ground.
5. Use calibrated strain relief hardware to support the 15-meter span, preventing the weight of the cable from exerting pull-force on the connector interfaces.
