Hardware Specifications

DCS Process Control Integration

The YCB141-M002 facilitates signal propagation via 10BASE-2 coaxial media, supporting the high-speed data requirements of the Vnet control bus. The cable construction features a shielded core design to mitigate electromagnetic interference and maintain signal integrity between control stations. With a defined characteristic impedance and precision BNC terminations, the assembly ensures low-latency communication packets required for real-time process monitoring and control. The internal geometry supports robust mechanical handling while maintaining the electrical properties necessary for reliable 10 Mbps operation within distributed control environments.

Frequently Asked Questions

Q: What is the significance of the 50 mm minimum bend radius during installation?

A: Maintaining the minimum bend radius prevents dielectric crushing and center-conductor kinking, which would otherwise alter the cable's characteristic impedance and cause signal reflections.

Q: Is this cable compatible with fiber-optic Vnet/IP upgrades?

A: No, this module is specific to the coaxial physical layer. Direct connection to Vnet/IP fiber-optic networks is not supported without appropriate media conversion.

Field Installation Guidelines

1. Ensure the Vnet bus is powered down before disconnecting or connecting the BNC interfaces to avoid potential ground-loop transients.
2. Verify that both ends of the coaxial segment are terminated with 50 Ohm BNC terminators to prevent signal oscillation.
3. Secure the cable using non-conductive cable ties to prevent mechanical stress on the connector ports.
4. Maintain a separation distance of at least 15 cm from high-voltage power conduits to reduce the risk of electromagnetic interference.
5. Inspect the BNC male connector pins for alignment and signs of oxidation to ensure low-resistance contact with the female bulkhead.
