Honeywell 51201420-004 Experion PKS FTA Cables

The Honeywell 51201420-004, also cataloged as the 51201420-004 Field Termination Assembly Cable, operates as a dedicated hardware component for physical signal interconnects within Honeywell Universal Control Network (UCN) platforms. This 4-meter non-shielded Field Termination Assembly (FTA) cable provides direct point-to-point wiring paths between field termination panels and I/O processing cards. Weighing 0.52 kg and jacketed with high-durability polyethylene insulation, the assembly maintains physical conductor integrity across high-density routing paths in Experion PKS and TDC 3000 control enclosures.

Hardware Specifications

DCS Process Control & Signal Interconnection

The passive 4-meter FTA cable routes low-voltage analog and discrete signal paths between Field Termination Assemblies and I/O processors across 4-20 mA HART and digital control topologies. Internal conductor geometry preserves channel-to-channel isolation parameters to mitigate cross-talk between adjacent signal lines. Built-in strain relief assemblies and polyethylene jacket materials maintain stable electrical contact resistance across industrial operating temperatures ranging from 0 to 60 deg C.

Frequently Asked Questions

Q: Does this 4-meter cable assembly draw operational current from the I/O backplane or field supply?

A: No, the cable functions entirely as a passive copper interconnection assembly and draws no operational current from the system backplane or external field power supplies.

Q: How should technicians route non-shielded FTA cables to prevent electromagnetic interference?

A: Technicians must run non-shielded cable runs through separate grounded metallic conduits or dedicated cable trays, maintaining at least 300 mm clearance from high-voltage AC power lines.

Field Installation Guidelines

Inspect the cable connector pins and locking latches prior to installation to confirm no physical deformation or contamination exists on contact surfaces. Align the cable head with the FTA socket and press firmly until both side retention clips snap securely into position. Avoid exceeding the minimum cable bend radius of 50 mm during enclosure routing to prevent internal conductor fatigue. Keep low-voltage non-shielded signal runs separated from high-power distribution lines and variable frequency drive wiring by a minimum gap of 300 mm.
