Yokogawa YCB141-M035 V net Cable

The Yokogawa YCB141-M035, also cataloged as the YCB141 V net Cable (10BASE-2), operates as a dedicated hardware component for high-speed deterministic control network communication within CENTUM VP and CS 3000 Field Control Station (FCS) systems. Configured for bus signal transmission between the processing units and remote nodes, the cable provides direct physical/electrical execution of real-time control network traffic.

Layout Configuration Selection: Layout 2

Suffix Breakdown & Model Matrix

The YCB141 nomenclature denotes specific physical parameters governed by the chosen alphanumeric options. The base model number designates the 10BASE-2 coaxial bus configuration, while the metric suffix indicates structural length:

Process Control & DCS Instrumentation Technical Attributes

This coaxial medium interfaces directly with V net processors to preserve high-frequency data integrity across an continuous 35 m span. The media architecture implements rigorous channel-to-channel isolation limits to block high-frequency common-mode noise propagation generated by surrounding heavy power switching gear. By adhering strictly to the 10BASE-2 signaling protocol, the physical cable layer ensures a reflection-free propagation path for real-time control variables, preventing data frame dropouts between integrated FCS racks.

Frequently Asked Questions

Q: Does the installation of the YCB141-M035 require distinct terminal resistor modules?

A: Yes, every segment of the 10BASE-2 V net trunk requires standard 50 ohm termination blocks at both physical end-points to mitigate signal reflection and frame distortion.

Q: How does the passive nature of this component alter voltage tracking across long distance nodes?

A: The passive physical layer does not inject or amplify power, meaning engineers must manage inline attenuation profiles to keep data levels within the operational tracking boundaries of the network interface.

Field Installation Guidelines

  • Trunk Layout Deployment: Route the cable assembly through distinct low-voltage wire trays, maintaining physical isolation from all high-current AC motor supply circuits.
  • Shield Grounding Matrix: Connect the structural outer metallic shield of the bus segment directly to the master instrumentation earth at one termination point.
  • Bend Limit Enforcement: Protect the internal physical core structure by enforcing a minimum static bend radius of 10 times the cable diameter during layout phases.
  • Connector Integrity Check: Inspect the locking interfaces for contamination or oxidation before locking the connections to prevent high-resistance contact loops.
