Yokogawa KS10-25*A Signal Cable

The Yokogawa KS10-25*A, also cataloged as the KS10 Signal Cable (50-50 pins), operates as a dedicated hardware component for 32-channel I/O signal interconnectivity within Yokogawa CENTUM VP and ProSafe-RS control systems. Configured with a 50-pin to 50-pin interface structure across a 25 m length, the cable transfers discrete and analog field instrumentation signals directly between I/O cards, terminal boards, and system node units. The assembly utilizes shielded twisted-pair conductors to preserve signal parameters across V net, ER bus, ESB bus, and RIO bus physical network layers.

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

The KS10-25*A cable supports high-density multi-channel analog signaling, enabling 4-20 mA HART loop protocol pass-through without signal attenuation or digital frequency distortion. The internal twisted-pair conductor geometry limits inter-pair crosstalk, allowing multi-core routing of sensitive 1-5 V DC and 4-20 mA instrument loops alongside HART digital carrier frequencies. When connected to isolated terminal blocks, the continuous foil shielding preserves individual channel-to-channel isolation barriers and shields cold junction compensation (CJC) reference lines from ambient low-frequency electromagnetic interference.

Frequently Asked Questions

Q: Does the 25 m cable length induce significant signal voltage drops on 4-20 mA current loops?

A: No. The low-resistance copper conductors are sized to maintain negligible voltage drop over 25 m, allowing standard 2-wire 24 V DC transmitter loops to operate within nominal voltage tolerances.

Q: Can the cable shield be grounded at both terminal ends?

A: System wiring specifications require grounding the overall cable braid shield at a single defined ground terminal bar (typically on the control cabinet frame) to prevent ground loop currents from flowing through the shield braid.

Q: How does the cable jacket react when installed near high-temperature steam lines?

A: The flame-resistant industrial outer jacket withstands continuous ambient operating temperatures up to +60 deg C. For installations exceeding +60 deg C, mechanical heat shielding or alternate conduit routing is required.

Field Installation Guidelines

Bending Radius Limits: Maintain a minimum bending radius between 50 mm and 100 mm during cabinet installation to prevent physical stress or insulation rupture on internal conductor pairs.
Shield Grounding: Connect the cable shield drain wire directly to the functional earth (FE) rail at the controller cabinet end. Ensure the field terminal end remains insulated to prevent multi-point ground paths.
Conduit Separation: Lay the KS10-25*A cable inside dedicated instrument wireways, keeping a minimum distance of 300 mm from 230 V AC / 400 V AC power lines and variable frequency drive motor leads.
Connector Engagement: Align the 50-pin pin-header housing carefully before tightening connector latching screws to guarantee positive contact pressure without bending pins.
