Configured for signal and power loop propagation in Symphony and INFI 90 control architectures, the ABB NKAS01-15 (NKAS01-15 Termination Cable) provides direct physical electrical interface execution between Multi-Function Processor (MMU) modules and termination assemblies.

Model Suffix Specifications

The NKAS01-15 is a standard-length shielded interconnect assembly. The "15" suffix denotes a fixed length of 15 feet (4.57 meters). No variable sub-configurations exist for this part number, as it utilizes a uniform conductor gauge and connector termination standard required for INFI 90 system backplane compatibility.

Hardware Specifications

Control System Performance

The cable utilizes backplane bus communication velocity standards consistent with Symphony INFI 90 hardware. The design incorporates shielding to minimize electromagnetic interference (EMI) and cross-talk, ensuring signal integrity across high-density I/O configurations. I/O density scaling remains compliant with standard INFI 90 specifications, as the cable impedance characteristics are matched to the MMU interface requirements, preventing signal attenuation or data corruption in long-run deployments.

Installation Guidelines

• Routing: Avoid running the cable parallel to high-voltage power lines or Variable Frequency Drive (VFD) output cables to maintain signal purity.

• Bend Radius: Adhere to a minimum bend radius of 10 times the outer diameter to prevent internal conductor fatigue.

• Connector Seating: Verify that all pins are aligned before insertion into the MMU or termination unit. Ensure the locking mechanism is fully secured to prevent vibration-induced loosening.

• Shielding: Ensure the cable shield is bonded to the equipment chassis ground at the designated grounding terminal to maximize noise immunity.

Frequently Asked Questions

• Q: Does this cable support hot-swapping?

  A: No. Disconnect all power sources from the MMU and termination unit before disconnecting the cable to avoid electrical shorts.

• Q: What is the maximum current capacity?

  A: The cable is rated for a continuous current of 5 A; verify that the connected load does not exceed this limit.

• Q: How do I verify cable integrity if communication errors occur?

  A: Use a digital multimeter to check for continuity on each conductor and ensure insulation resistance exceeds required system standards.

• Q: Is this cable shielded?

  A: Yes, the cable features internal shielding to protect against electrical noise within the control cabinet environment.

• Q: Can I shorten or extend the 15-foot length?

  A: Modifying the length alters the impedance and capacitance characteristics, which can lead to communication errors in Symphony systems.

• Q: How does the operating temperature affect the cable?

  A: The insulation material is specified for -25 deg C to +80 deg C; exceeding these limits will cause embrittlement or degradation of the outer jacket.

• Q: Are the connectors compatible with standard DB-style interfaces?

  A: The cable utilizes proprietary ABB INFI 90 system connectors; verify interface compatibility before attempting to connect to non-ABB hardware.

• Q: Does the cable require routine maintenance?

  A: Inspect for physical damage or wear to the insulation jacket periodically, especially in areas subjected to vibration or mechanical movement.
