The ABB NKTT01-10, also cataloged as the NKTT01 termination cable, provides a physical termination interface for signal conductors within ABB Bailey Infi 90 hardware connections. The assembly is specified as a 10 ft cable with an integrated 75 ohm terminator.

Model and Configuration

The NKTT01-10 designation identifies the NKTT01 cable assembly with the -10 length variant. The supplied data specifies a 10 ft cable configuration and a 75 ohm termination element.

Hardware Specifications

Industrial Control Interface Characteristics

For ABB industrial control installations, termination components affect the electrical behavior of connected signal conductors. The NKTT01-10 incorporates a specified 75 ohm termination element rated at 0.25 W. The termination resistance should remain matched to the intended Infi 90 circuit and should not be substituted with a different resistance value without confirming the system wiring specification.

Ordering Information

Cable Installation Guidelines

• Route the termination cable separately from high-voltage switching conductors where practical.
• Avoid sharp bends, crushing, or excessive mechanical tension on the cable assembly.
• Maintain conductor insulation and connector integrity during installation.
• Use the specified termination point for the intended Infi 90 circuit.
• Do not replace the 75 ohm termination element with an unverified resistance value.
• Keep cable routing away from strong electromagnetic interference sources where system wiring practice requires it.
• Verify continuity and termination resistance before energizing the associated circuit.

Frequently Asked Questions

• What is the ABB NKTT01-10?
  It is a Bailey Infi 90 termination cable assembly incorporating a specified 75 ohm termination element.
• What is the cable length?
  The supplied specification identifies the NKTT01-10 as a 10 ft cable configuration.
• What termination resistance is specified?
  The integrated terminator is specified as 75 ohm with a tolerance of +/- 1% and a 0.25 W rating.
• What voltage is the cable rated for?
  The specified voltage rating is 300 V AC/DC. Installation should remain within the applicable circuit and wiring requirements.
• What current can each conductor carry?
  The supplied specification gives a conductor current rating of 3-5 A. Actual circuit loading must remain within system wiring limits.
• What is the operating temperature range?
  The specified operating range is -20 to +80 deg C with 5-95% RH non-condensing humidity.
• Is NKTT01-10 an electronic module?
  No. It is identified as a termination cable assembly. No electronic processing or independent power consumption is specified.
• Can the 75 ohm terminator be replaced with another value?
  It should not be changed without confirming the associated Infi 90 circuit requirements, because termination resistance affects signal-line electrical characteristics.
