Honeywell MU-KFTA05 FTA I/O Cable | 50-Pin 5-Meter Ribbon

Cable Overview and Application Scope

This I/O cable assembly provides the essential physical link between field termination assemblies and control system modules. It transmits digital and analog signals reliably across the cabinet infrastructure. The cable features a 50-pin connector on each end for straightforward installation. Its flexible construction simplifies routing through cable ducts and tight spaces. This assembly serves as a direct replacement for original Honeywell cabling solutions.

Connector Design and Contact Quality

Each connector housing features a metal backshell for improved mechanical strength. Gold-plated contacts ensure low contact resistance and excellent signal fidelity. The connectors include jack-screws for secure mating with panel receptacles. These jack-screws prevent accidental disconnection due to vibration. Each pin maintains reliable contact even after multiple insertion cycles.

Signal Integrity and Electrical Performance

The MU-KFTA05 maintains consistent impedance for clean signal transmission across all 50 conductors. Its low capacitance design minimizes signal distortion on high-speed data lines. Adjacent conductors experience negligible crosstalk due to controlled dielectric properties. This cable supports both analog measurement signals and digital communication busses. Use it within its rated voltage and current limits for optimal performance.

Physical Dimensions and Handling

This cable assembly measures 5 meters from connector to connector. Its flat ribbon design allows for easy folding and shaping inside cabinets. The cable remains flexible even at low temperatures for convenient installation. Its lightweight construction reduces strain on connected components. Plan cable routing to avoid sharp bends or excessive tension.

Installation and Routing Recommendations

Route the cable through designated cable trays or ducting channels. Secure the cable using nylon cable ties at regular intervals. Leave sufficient service loops to accommodate future maintenance access. Mate each connector carefully to avoid bending any pins. Tighten the jack-screws firmly to lock the connection in place.

Compatibility and System Integration

This cable interfaces directly with Honeywell FTA boards and I/O modules. It serves as a key component in Series T and Series C system architectures. The cable works with both digital input/output and analog termination assemblies. Verify the correct cable length before installation. This assembly replaces the equivalent Honeywell part number without modification.

Storage and Handling Precautions

Store the cable in a clean, dry environment away from direct sunlight. Avoid stacking heavy objects on top of the cable assembly. Protect the connectors with dust caps during storage periods. Handle the cable gently to prevent insulation damage. Inspect the connectors for bent pins before each use.
