Description

Yokogawa YCB141-M035 V net Cable

The Yokogawa YCB141-M035, also cataloged as the YCB141 V net Cable, operates as a dedicated hardware component for coaxial data transmission across CENTUM VP and ProSafe-RS networks. It is engineered to maintain signal integrity for 10BASE-2 standard communication in distributed industrial control systems.

Process Control Integration

The YCB141-M035 supports channel-to-channel isolation inherent to Yokogawa DCS and SIS networks. The coaxial shielding minimizes cross-talk and EMI/RFI interference between parallel control loops. It maintains deterministic 10BASE-2 communication for HART/4-20 mA loop protocol integration and FOUNDATION Fieldbus or Profibus PA extensions where interface adapters are applied. Cold junction compensation (CJC) considerations in connected analog modules are preserved by controlled cable impedance and consistent grounding practices.

Frequently Asked Questions

Q: Can the YCB141-M035 be cut or field-terminated to a different length?
A: No. The cable is pre-cut to 35 m with factory termination to maintain impedance and shielding integrity. Field modification may compromise signal quality.

Q: How should the cable shielding be grounded?
A: Shielding should be connected to a single-point system ground at one end only to avoid ground loops.

Q: Is this cable suitable for hot-swap operations of FCS/HIS nodes?
A: The cable supports physical bus connection/disconnection only under powered-down conditions. Hot-swap is not recommended due to potential transient signals on the coaxial bus.

Field Installation Guidelines

• Route the cable away from high-voltage AC lines or heavy motor drives to reduce induced noise.
• Maintain minimum bending radius of 50 mm at all turns; do not exceed specified curvature.
• Connect the solderless lugs with M4 screws firmly to designated terminals, ensuring full contact with the bus interface.
• Avoid stacking or parallel bundling with other signal cables; maintain separation per plant wiring standards.
• Secure cable along trays or conduits using non-metallic ties to prevent mechanical stress.
• Verify continuity and shielding integrity before commissioning system nodes.
