MU-KFTA08 | Honeywell | Field Termination Assembly Cable

Configured for signal routing between field termination assemblies and control modules in Honeywell Experion PKS platforms, the Honeywell 51201420-008 (MU-KFTA08 Field Termination Assembly Cable) provides direct physical/electrical execution.

Hardware Specifications

Channel-to-Channel Isolation & 4-20 mA Loop Integration

The cable assembly provides structured multi-wire routing between Honeywell I/O processors and field termination sub-bases. Designed to maintain signal purity when operating parallel to 4-20 mA HART loop protocol wiring, the continuous foil-and-braid shielding structure isolates internal conductor pairs from external electromagnetic noise. Channel-to-channel isolation parameters are maintained by preserving fixed physical spacing across factory-molded connector pins.

Frequently Asked Questions

Q: Does the MU-KFTA08 cable assembly draw operational current from the I/O rack backplane?

A: No. The MU-KFTA08 is a passive field interconnect assembly that contains no active processing logic or internal backplane power draw.

Q: How does the internal shield barrier prevent field signal degradation?

A: The high-density shield layer encloses the conductor bundle to attenuate ambient electromagnetic and radio-frequency interference (EMI/RFI) before transient voltages can form on sensitive analog loops.

Q: What insulation voltage limits govern the internal conductors of the assembly?

A: The conductor insulation jacket is tested and rated for an overall operating potential limit of 300 V.

Field Installation Guidelines

• Align connector orientation keys precisely prior to seating plugs into host I/O boards or field termination cards to avoid pin deformation.
• Route signal cables through low-voltage instrument ducts, maintaining mandatory physical clearance from 480 VAC power lines and drive outputs.
• Anchor the cable jacket at cabinet entry points using strain relief clamps to prevent mechanical tension from stressing connector pins.
• Terminate the shield drain wire to the designated central system instrumentation grounding bar in accordance with factory guidelines.
• Observe minimum bend radius limits during tray installation to prevent shielding braid separation and conductor stress.
