Yokogawa KS1-03*B Signal Cable

The Yokogawa KS1-03*B, also cataloged as the KS1 Signal Cable, operates as a dedicated hardware component for multi-bus data transmission between I/O modules and terminal boards within Yokogawa CENTUM VP and ProSafe-RS control systems. Built with multi-strand high-grade copper conductors and dual-layer braided shielding, this 3 m cable assembly maintains physical transmission paths across V net (10BASE-5), ER bus (10BASE-2), ESB bus, and RIO bus physical network layers. The rugged assembly suppresses ambient electromagnetic interference (EMI) to deliver non-attenuated signal execution between local control nodes and field terminal interfaces.

4-20 mA HART Loop Protocol & Channel-to-Channel Isolation Integration

The KS1-03*B signal cable accommodates 4-20 mA HART loop protocol carrier frequencies by preserving signal wave integrity over its low-loss polyethylene/PVC dielectric paths. When routing analog telemetry between field terminal blocks and DCS input cards, the multi-strand twisted-pair geometry restricts cross-channel capacitive coupling, preventing channel-to-channel isolation degradation across adjacent process loops. The low-impedance braided outer shield drains induced high-frequency electrical noise to ground, ensuring precise cold junction compensation (CJC) mV reference readings from field thermocouples connected to terminal boards.

Frequently Asked Questions

Q: How does the dual-layer shielding affect grounding procedures during installation?

A: The combined braided shield and foil wrap isolate signal lines from high-frequency electromagnetic noise. To prevent ground potential loop currents across the shield, terminate the drain wire or braided shield to functional earth at one designated cabinet end only.

Q: Can this cable be deployed in hazardous locations requiring explosion protection?

A: When ordered with the /NL option code, the assembly complies with CSA non-incendive instrumentation standards for installation in designated Division 2 hazardous area environments without compromising signal execution.

Q: What is the mechanical limitation regarding cable routing inside crowded control cabinets?

A: Field technicians must maintain a minimum bending radius of 50 mm to 100 mm depending on the specific bus cable type (coaxial vs. twisted-pair). Exceeding this bend limit risks damaging the inner dielectric insulation and compromising EMI shield coverage.

Field Installation Guidelines

Cabinet Routing & Minimum Bend Radius: Lay the cable along dedicated wire ducts inside the enclosure, ensuring the physical bend radius does not drop below 100 mm at turn points to protect internal copper conductors.
Shield Grounding & Drainage: Connect the cable shield drain lug to the main cabinet functional earth (FE) bus bar. Ensure the shield remains floating at the remote terminal end to avoid ground loop currents across the 3 m span.
Separation from Power Lines: Maintain a minimum clearance distance of 200 mm between the KS1-03*B signal run and high-voltage AC power distribution wiring or variable frequency drive cabling.
Connector Strain Relief: Fasten all connector strain-relief hardware and screw locks firmly before applying tension, preventing mechanical stress on internal solder joints or screw terminal contacts.
