MU-KFTA15 Honeywell Field Termination Assembly Cable

The Honeywell 51201420-015, also cataloged as the MU-KFTA15 Field Termination Assembly Cable, operates as a dedicated hardware component for multi-channel field signal interconnection and data routing within Honeywell DCS platforms.

Hardware Specifications

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

The 15-meter cable assembly provides structured multi-conductor routing between field termination sub-bases and process I/O cards. Designed to operate alongside 4-20 mA HART loop protocol architectures and RS485 digital communication buses, the overall shield construction attenuates ambient high-frequency noise. Channel-to-channel isolation limits mutual capacitance coupling and prevents ground loops across parallel analog signal lines.

Frequently Asked Questions

Q: Does the MU-KFTA15 cable require an external power supply to operate?

A: No. The MU-KFTA15 functions as a passive physical interconnect assembly, carrying 24 VDC power and 0-10 VDC or RS485 signals without internal power consumption.

Q: Can the 15-meter cable length be shortened in the field?

A: Modification or field-cutting of pre-terminated connectors is not recommended, as altering factory solder and pin terminations degrades impedance characteristics and shield integrity.

Q: How does the cable shield limit signal corruption over the 15-meter run?

A: The continuous overall shielding layer channels electromagnetic transients directly to the system drain wire, suppressing noise induction across 0-10 VDC analog and RS485 differential lines.

Field Installation Guidelines

• Align plug keying tabs precisely with header slots on termination assemblies prior to seating to avoid pin bending.
• Maintain recommended minimum bend radius parameters along the entire 15-meter cable tray route to prevent conductor fatigue.
• Segregate signal extension cables from high-voltage AC power lines and variable frequency drive output conduits.
• Ground the shield drain conductor directly to the central system instrumentation earth bus bar.
• Secure strain relief fittings at panel entry points to isolate the multi-pin connectors from mechanical tension.
