YCB146 CENTUM DCS Network Branch Connector Original

Product Overview

The Yokogawa YCB146 functions as a high-precision T-shaped branching unit for the V net and ER Bus architectures. It enables the physical splitting of control bus signals, allowing multiple nodes or modules to interface with the primary DCS backbone without signal degradation. Designed specifically for the CENTUM series, this connector maintains strict signal synchronization and data integrity across complex automation networks. Its robust construction ensures that high-speed communication remains uninterrupted, even in environments with significant electromagnetic interference or physical vibration.

Technical Specifications

The YCB146 adheres to rigorous industrial communication standards to prevent network timeouts:

Engineering Advantages

• Maintains Bus Impedance: The YCB146 optimizes electrical impedance at branching points. This prevents signal reflections that typically cause packet loss or communication "jitter" in high-speed DCS networks.

• Simplifies Network Expansion: The T-shaped design allows engineers to add new I/O nodes or controller units to an existing V net segment without rerouting the entire bus backbone. This significantly reduces downtime during system upgrades.

• Superior EMI Shielding: The heavy-duty 2kg construction provides excellent shielding against electromagnetic interference. This protection proves vital in control cabinets located near high-voltage motor starters or variable frequency drives (VFDs).

• Vibration-Resistant Connections: Yokogawa utilizes high-retention contact surfaces within the YCB146. These internal connections resist the mechanical loosening caused by floor vibrations in power plants and manufacturing facilities, ensuring 24/7 network availability.

FAQs

Q1: Can the YCB146 be used for both V net and V net/IP systems?

A1: The YCB146 primarily supports traditional V net and ER Bus coaxial-style architectures. For V net/IP systems, which utilize Ethernet-based switching, you would typically use industrial Ethernet switches rather than T-shaped branching connectors.

Q2: Does this connector require an external power supply?

A2: No. The YCB146 is a passive branching component. It manages the physical layer of the control bus signal and does not require a separate power feed to operate.

Q3: How does the weight of the YCB146 (2 kg) impact installation?

A3: The substantial weight reflects its industrial shielding and robust internal components. We recommend secure mounting on the cabinet panel or rack frame to ensure the weight does not put undue mechanical stress on the connecting bus cables.

Q4: How do I verify that this YCB146 is a genuine Yokogawa part?

A4: We supply only 100% Brand New and Original Yokogawa hardware. Each unit features the official manufacturer labels, serial numbers, and comes in original factory packaging, backed by our 12-month warranty.
