• Color-Coded Conductors: Standardized color coding simplifies installation, troubleshooting, and maintenance by enabling rapid circuit identification without continuity testing
• Flexible Construction: Optimized cable flexibility facilitates routing through crowded marshalling cabinets, cable trays, and conduit while maintaining minimum bend radius requirements

DCS Integration Applications

This termination cable addresses critical wiring requirements across Bailey INFI 90 and Net 90 distributed control architectures where reliable field device connectivity directly impacts process control performance:

• Analog I/O Termination: Connects 4-20mA transmitters, RTD temperature sensors, and analog control valves to INFI 90 analog input/output modules with shielded signal paths preventing measurement errors from electrical noise
• Digital I/O Wiring: Interfaces discrete field devices including limit switches, solenoid valves, motor starters, and alarm contacts to digital I/O modules with reliable contact closure detection
• Fieldbus Communication: Provides physical layer connectivity for INFI-Net and Modbus fieldbus networks linking distributed I/O racks, operator stations, and engineering workstations
• Marshalling Cabinet Installation: Facilitates organized wiring between field termination blocks and DCS I/O modules in marshalling cabinets with proper segregation of signal types and voltage levels
• Redundant System Wiring: Supports dual-channel redundant I/O configurations in critical control loops requiring continuous operation during module failures or maintenance
• Retrofit & Upgrade Projects: Enables replacement of aging cables in legacy INFI 90 and Net 90 installations without system downtime through hot-swappable termination procedures
• Hazardous Area Interfacing: Connects intrinsically safe barriers and galvanic isolators to DCS I/O modules in applications requiring Zone 1/2 or Division 1/2 hazardous area protection

Bailey INFI 90 & Net 90 System Compatibility

The NKTT01-3 integrates seamlessly within ABB's Bailey INFI 90 and Net 90 distributed control ecosystems, providing standardized connectivity between field marshalling terminals and I/O module terminal blocks. The cable's pre-configured connectors match INFI 90/Net 90 module pinouts, eliminating field wiring errors and reducing commissioning time. Compatible with analog input, analog output, digital input, digital output, and specialty I/O modules across the complete Bailey product portfolio.

Engineering Design Excellence

• Factory-Tested Quality: Each cable undergoes continuity testing, insulation resistance verification, and shield integrity validation before shipment, ensuring zero-defect installation
• Standardized Length: 3-meter length accommodates typical marshalling cabinet layouts while minimizing excess cable that could create cable management challenges or signal degradation
• Durable Jacket Material: Abrasion-resistant outer jacket withstands cable tray installation, conduit pulling, and long-term exposure to oils, solvents, and cleaning agents
• Low Capacitance Design: Optimized conductor spacing and insulation materials minimize cable capacitance, preserving signal rise times and enabling accurate high-speed digital communication
• Grounding Provisions: Proper shield termination points enable single-point grounding configurations that eliminate ground loops while maintaining EMI protection effectiveness
• Documentation Support: Complete wiring diagrams, pinout specifications, and installation guidelines facilitate error-free installation by instrumentation technicians

Installation & Commissioning

Cable installation involves routing from field marshalling terminals to DCS I/O module terminal blocks with proper segregation from power cables and high-voltage circuits. Shield connections require single-point grounding at the DCS end to prevent ground loops while maintaining EMI immunity. Termination involves securing conductors to screw terminals with proper torque specifications and verifying continuity before energizing circuits. Commissioning includes insulation resistance testing, shield continuity verification, and signal integrity validation—typically completed in 15-20 minutes per cable.
