Honeywell 51201420-010 MU-KFTA10 FTA Cable

Product Overview

The Honeywell 51201420-010 MU-KFTA10 provides a reliable interconnection between field termination assemblies and I/O modules. This cable assembly transmits discrete and analog signals with minimal signal degradation. It bridges the physical gap between the FTA board and the main controller chassis. The unit suits Honeywell Series C and TDC 3000 system architectures.

Technical Specifications

Physical Characteristics and Construction

This cable assembly measures 1.0 meter in total length from end to end. The assembly weighs approximately 0.15 kg for easy handling. It features a flat ribbon construction with 50 color-coded conductors. The PVC insulation provides flexibility while maintaining signal isolation between adjacent wires. Each end terminates with a 50-pin D-sub connector for secure mating. The connectors include metal thumbscrews for reliable mechanical locking.

Electrical Performance and Signal Integrity

The 51201420-010 MU-KFTA10 maintains consistent impedance across all 50 conductors. The flat ribbon design minimizes crosstalk between adjacent signal lines effectively. Each conductor carries 28 AWG tinned copper for low resistance transmission. The insulation material resists moisture and common industrial chemicals. This cable supports both digital and analog signals without degradation. Consequently, it preserves signal fidelity over the full transmission distance.

Connector Interface and Compatibility

Both ends feature standard 50-pin D-sub connectors with pin assignments matching Honeywell specifications. These connectors mate directly with FTAs and I/O modules in the Series C lineup. The metal thumbscrews provide secure attachment and prevent accidental disconnection. The connector housings include polarization features to prevent incorrect orientation. This design eliminates the risk of reversed connections during installation.

Installation and Application Guidance

You can route this cable within cabinet wireways or cable trays for organized installation. The flat profile allows convenient bundling with other ribbon cables. Always avoid sharp bends that might damage internal conductors during routing. The cable length of 1.0 meter suits most cabinet configurations perfectly. For longer distances, use multiple cables with intermediate connectors. Verify that both mating connectors are clean and free of debris before insertion.

Durability and Environmental Resistance

This cable meets UL and CSA standards for industrial control wiring. The PVC insulation withstands typical ambient temperatures in control rooms. The tinned copper conductors resist oxidation and maintain low contact resistance. The connector contacts feature gold-plating for reliable signal transfer over repeated mating cycles.
