YOKOGAWA YCB149 V-net Converter Connector | DCS Communication Module | CENTUM Platform
Engineering Background: The YOKOGAWA YCB149 is a dedicated V-net (Vnet) converter connector module engineered for YOKOGAWA’s CENTUM distributed control system (DCS) platform. V-net is YOKOGAWA’s proprietary high-speed, deterministic control bus that forms the backbone of CENTUM VP, CENTUM CS 3000, and legacy CENTUM CS architectures. The YCB149 serves as the physical and electrical interface between field devices, I/O modules, and the V-net control bus, ensuring reliable, low-latency signal transmission in mission-critical process automation environments.
Product Positioning: Designed for procurement engineers and system integrators maintaining or expanding YOKOGAWA CENTUM DCS installations, the YCB149 is a direct OEM replacement and expansion component. It is the correct choice when replacing failed converter connectors, adding new V-net nodes, or commissioning parallel redundant control loops in refinery, chemical, power generation, and pharmaceutical plant environments.

System Architecture & Signal Flow
In a CENTUM DCS architecture, the V-net serves as the primary control bus connecting the Human Interface Station (HIS), Field Control Stations (FCS), and Engineering Workstations (EWS). The YCB149 V-net Converter Connector acts as the physical termination and signal conversion point at each node, converting the V-net bus signal to the appropriate electrical interface for connected I/O modules or field devices.
Typical Signal Path: HIS / EWS → V-net Bus → YCB149 Converter Connector → FCS / I/O Module → Field Instruments
The YCB149 ensures signal integrity across the V-net segment, supporting the high-speed, deterministic communication required for real-time process control. In redundant configurations, dual YCB149 modules operate in parallel, with automatic failover managed by the CENTUM FCS controller.

Technical FAQ
Q: Is the YCB149 compatible with CENTUM VP R6.x?
A: The YCB149 is designed for the CENTUM V-net bus architecture. Compatibility with specific CENTUM VP revisions should be confirmed against your system’s hardware revision documentation. Contact our technical team for confirmation.
Q: Can the YCB149 be used in a redundant V-net configuration?
A: Yes. CENTUM DCS supports dual-redundant V-net bus configurations. Two YCB149 modules are required per redundant node — one per bus segment.
Q: What is the lead time for YCB149?
A: Standard in-stock orders ship within 3–5 business days. For large quantities or urgent requirements, contact us for expedited options.
Q: Do you provide a test report or certificate of conformance?
A: Yes. A certificate of conformance and functional test report are available upon request for all orders.
Q: What export documentation is provided?
A: We provide commercial invoice, packing list, country of origin certificate, and HS code documentation for all international shipments.
