The ABB NKAS01-10 serves as the primary NKAS01 Analog Module Termination Cable utilized to execute point-to-point analog signal routing between I/O cards and terminal units across Bailey Infi 90 platforms. It routes multi-channel low-voltage analog signals, providing multi-conductor physical interconnection rated for 300 V AC and up to 2 A per conductor without introducing channel cross-talk or measurement offset errors.

Cable Assembly Designator & Subsystem Structure

• NKAS01: Base part identifier for Bailey Infi 90 analog module terminal unit interconnect cables.
• -10: Specific cable designator for pre-terminated field wiring interfacing (10 ft nominal / 10 in physical connection span rating).
• Conductor Wiring: 20-22 AWG multi-conductor copper bundle with 300 V insulation rating and 80 deg C thermal barrier.

Physical & Electrical Data

Backplane Integration & High-Density IO Scaling

The NKAS01-10 cable maintains analog measurement precision across high-density I/O density scaling configurations in Infi 90 racks. By ensuring consistent conductor resistance and low signal capacitance across all channels, it prevents voltage drop and loop noise that interfere with backplane bus communication velocity and analog-to-digital processing. The cable construction supports uninterrupted firmware flash compatibility during module hot-swaps, protecting internal multiplexing logic on host processing cards.

Cabinet Interconnect & Cable Handling Rules

• Connector Latching: Fully engage and secure screw-locks on both cable header connectors to prevent pin contact resistance and intermittent analog input drops.
• Routing Isolation: Keep analog signal cable runs separate from high-current AC lines and inductive loads by at least 200 mm to avoid noise coupling.
• Strain Relief: Fasten the cable assembly to internal cabinet tie-bars within 150 mm of the connection header to eliminate physical strain on terminal pins.
• Static Bend Radius: Maintain a minimum static bend radius of 60 mm during installation inside wiring ducts to preserve conductor insulation and shield coverage.

Operational FAQ & Technical Constraints

• What is the maximum continuous current capacity per conductor on the NKAS01-10?

  Each conductor path within the cable assembly is rated to carry up to 2 A continuous current at 300 V AC.

• Can this termination cable be disconnected while the host analog module is powered?

  Disconnecting under power interrupts live 4-20 mA or voltage loops, causing open-circuit fault detection on controller channels.

• How does conductor gauge size affect signal loss across this cable assembly?

  The 20-22 AWG conductors minimize series loop resistance, preserving instrument accuracy across 1-5 V or 4-20 mA signal ranges.

• What voltage isolation rating applies to the internal conductor insulation?

  The wire insulation layer is factory tested and rated for continuous operation up to 300 V AC.

• Does the NKAS01-10 cable require external ground wire connections?

  The cable shield grounds automatically through the mating header pin assignment on the termination module chassis.

• What is the maximum operating ambient temperature for this cable assembly?

  The cable insulation material is rated for continuous field exposure from -20 deg C up to +80 deg C.

• How does this cable prevent channel-to-channel cross-talk in analog loops?

  Individually twisted conductor pairs and internal shielding isolate low-level analog signals from adjacent channel interference.

• What maintenance check is recommended for aging cable installations?

  Inspect terminal connector pin contacts for oxidation and measure pin-to-pin loop resistance to ensure values stay under 1 ohm.
