Yokogawa YCB111-M120 Vnet Cable

Product Introduction

The Yokogawa YCB111-M120 VNet Cable is a high-performance industrial communication cable specifically designed for Yokogawa’s VNet control networks. Engineered for reliable and noise-resistant data transmission, this cable provides a stable communication link for Distributed Control Systems (DCS) and plant-wide automation networks. With a factory-specified length of 120 meters, the YCB111-M120 ensures consistent signal integrity across long cable runs, making it ideal for large process facilities that require dependable real-time control and monitoring.

Technical Specifications

Applications

The YCB111-M120 VNet Cable is used wherever reliable and secure industrial communication is critical:

• Distributed Control Systems (DCS): Provides dependable links between controllers, operator stations, and I/O nodes.

• Power Generation Plants: Maintains continuous data transfer for turbine monitoring and control.

• Oil & Gas Processing: Ensures secure communication in environments with heavy electromagnetic interference.

• Chemical & Petrochemical Facilities: Supports high-speed, real-time process control.

• Water Treatment Plants: Guarantees long-distance data transmission for remote pumping and filtration stations.

• Factory Automation: Integrates production line controls with supervisory systems.

Advantages

• High Signal Integrity: Low attenuation and precise impedance maintain data accuracy over long distances.

• Robust Shielding: Dual-layer shielding protects against electromagnetic interference (EMI) and radio frequency interference (RFI).

• Industrial Durability: Flame-retardant, chemical-resistant jacket ensures reliability in harsh plant conditions.

• Easy Installation: Flexible multi-strand conductors simplify routing through trays or conduits.

• Optimized for VNet: Fully compatible with Yokogawa VNet protocols and legacy installations.

• Long Cable Run Capability: The 120 m length enables extended connections without repeaters.

• Low Maintenance: Designed for years of continuous service with minimal inspection needs.

FAQ

1. What is the nominal impedance of the YCB111-M120 cable?
   100 Ω balanced, ideal for high-speed industrial communication.

2. Is this cable compatible with standard Ethernet devices?
   It is optimized for Yokogawa VNet systems, but can interface with compatible industrial Ethernet hardware supporting the same specifications.

3. How does the cable prevent electromagnetic interference?
   Through double shielding using aluminum foil and a copper braid to block EMI and RFI.

4. Can the cable operate in high-humidity environments?
   Yes, the jacket is moisture-resistant, making it suitable for humid or damp areas.

5. Is the cable flame-retardant?
   Yes, it meets industrial flame-resistance standards for safety.

6. What is the maximum recommended bend radius during installation?
   Typically 10 times the outer diameter, approximately 100 mm.

7. Does the cable require termination resistors?
   Termination depends on the network design; VNet systems often use matched terminations at endpoints.

8. Can the cable be used outdoors?
   Yes, if properly protected from direct UV exposure or installed in conduits.

9. Is the conductor solid or stranded?
   It uses high-purity multi-strand copper for flexibility and conductivity.

10. What is the frequency range supported for data transmission?
    It supports high-frequency signaling consistent with VNet requirements, typically up to several MHz.
