Advanced Cable Design Features

The NKTU01-12 incorporates sophisticated construction and termination techniques essential for reliable DCS signal transmission:

• Factory Termination Quality: Precision-crimped connectors with gold-plated contacts ensure low contact resistance and long-term reliability, eliminating field termination errors and reducing installation time by 75% compared to bulk cable
• Shielded Twisted Pair Architecture: Individual pair shielding combined with overall cable shield provides superior noise immunity in electrically harsh industrial environments with VFDs, welders, and high-current switching equipment
• Keyed Connector Design: Mechanical keying prevents incorrect mating and ensures proper pin alignment during installation, protecting sensitive controller and I/O module electronics from reverse polarity damage
• Strain Relief Integration: Molded strain relief boots at both connector ends prevent cable damage from flexing, vibration, and tension during installation and service, extending cable life beyond 20 years
• Color-Coded Conductors: Standardized wire color scheme simplifies troubleshooting, modification, and documentation of control system wiring without requiring continuity testing
• Flexible Jacket Material: Industrial-grade outer jacket resists oil, chemicals, abrasion, and UV exposure while maintaining flexibility for routing through cable trays and conduit systems

DCS System Integration Applications

This termination cable addresses critical interconnection requirements across ABB Bailey INFI 90 and Net 90 distributed control architectures where reliable wiring directly impacts system availability and process control integrity:

• Controller to Termination Unit Connections: Links INFI 90 controller racks to field termination panels housing I/O modules, enabling distributed architecture with controllers in control rooms and I/O near process equipment
• I/O Module Expansion: Connects additional termination units to existing controller infrastructure during plant expansions, capacity increases, or process modifications without rewiring existing installations
• Redundant Controller Wiring: Implements dual-cable connections in redundant controller configurations providing automatic failover without signal interruption during controller maintenance or failure
• Remote I/O Applications: Extends I/O capacity to remote process areas up to 12 meters from controller racks in applications where local I/O mounting is impractical or unsafe
• Marshalling Cabinet Interconnects: Connects controller racks in main control rooms to marshalling cabinets housing field termination blocks and intrinsic safety barriers for hazardous area wiring
• System Migration Support: Facilitates phased migration from INFI 90 to modern control platforms by maintaining existing field wiring while upgrading controller hardware incrementally
• Spare Cable Inventory: Provides ready-to-install replacement cables for emergency repairs, reducing mean time to repair (MTTR) from hours to minutes during critical system failures

Bailey INFI 90 & Net 90 System Architecture

The NKTU01-12 integrates within ABB's legacy Bailey control system ecosystem, connecting INFI 90 controllers, Net 90 communication modules, and termination units housing analog input, analog output, digital input, and digital output modules. The cable supports both local I/O configurations with termination units adjacent to controllers and remote I/O architectures with distributed termination panels near process equipment. Proper cable routing through grounded cable trays and conduit systems maintains signal integrity and electromagnetic compatibility.

Engineering Design Excellence

• Pre-Tested Assembly: Factory testing of all conductor pairs and shield continuity ensures 100% functional cables eliminating field troubleshooting of wiring faults during commissioning
• Standardized Length: 12-meter length accommodates typical control room to marshalling cabinet distances while minimizing excess cable that creates clutter and maintenance challenges
• Robust Construction: Industrial-grade materials and assembly processes withstand installation handling, cable tray routing, and decades of service in temperature-cycling industrial environments
• EMC Compliance: Shielding effectiveness exceeds IEC 61000 electromagnetic compatibility requirements for industrial control equipment in high-noise environments
• Replacement Compatibility: Direct replacement for original ABB Bailey cables maintaining backward compatibility with installed INFI 90 and Net 90 systems dating to 1980s installations
• Documentation Support: Cable labeling and documentation facilitate system modifications, troubleshooting, and compliance with plant engineering standards

Installation & Commissioning

Cable installation involves routing through cable trays or conduit from controller rack to termination unit, maintaining minimum bend radius of 10x cable diameter. Connectors mate with keyed receptacles on controller modules and termination units with positive locking mechanisms. Shield connections terminate at both ends through connector backshells maintaining 360-degree shield continuity. Installation verification includes visual inspection of connector seating, shield continuity measurement, and functional testing of all I/O points—typically completed in 15-20 minutes per cable.

Quality Standards & Compliance

Manufactured under ISO 9001:2015 quality management systems with 100% electrical testing and visual inspection. Complies with UL 1277 industrial control cable standards, CSA C22.2 electrical safety specifications, and CE electromagnetic compatibility directives. Meets IEC 61131-2 programmable controller wiring requirements and NFPA 70 National Electrical Code installation standards. RoHS compliant with lead-free materials and environmentally responsible manufacturing.
