Honeywell 6561430051 PLC Cable

The Honeywell 6561430051, also cataloged as the 6561430051 PLC Cable, operates as a dedicated hardware component for analog and digital signal transmission between C300 controllers and Field Termination Assemblies (FTAs) within Experion PKS and TDC 3000 networks.

Hardware Specifications

Process Control and DCS Instrumentation Characteristics

• 4-20 mA HART loop protocol: The 6561430051 is engineered to maintain signal integrity for HART-enabled field devices connected through the C300 backplane. Its internal construction minimizes resistive loss, ensuring that digital communication signals superimposed on the 4-20 mA analog loop are not attenuated.

• Channel-to-channel isolation: The cable utilizes shielded-pair construction to maintain electrical isolation between individual signal channels. This design prevents crosstalk, which is necessary when carrying mixed-signal payloads—such as sensitive analog inputs and high-speed digital outputs—through the same physical conduit.

• Cold junction compensation (CJC): In applications where the cable interfaces with thermocouple-based FTAs, the wiring geometry and thermal-insulative shielding properties assist in stabilizing the temperature profile at the termination point, supporting consistent CJC performance by the downstream controller.

• FOUNDATION Fieldbus / Profibus PA connectivity: The cable’s impedance characteristics are matched to the requirements of the C300 system architecture, providing the signal bandwidth needed for high-density digital fieldbus protocols without inducing signal reflections or excessive jitter.

Frequently Asked Questions

Q: Is this cable rated for use in hazardous areas?

A: The 6561430051 is designed for use in standard industrial control cabinets. For applications in Class I, Div 2 or other hazardous locations, verify that the cable’s jacketing and termination conform to the specific safety barrier requirements mandated by the site’s installation standards.

Q: Can this cable be used for signal runs between remote IO cabinets?

A: This cable is designed for point-to-point connections between the C300 controller and the FTA. It is not intended for inter-cabinet runs over long distances; such applications require specialized field-wiring practices and potentially signal boosters or protocol-specific repeaters.

Field Installation Guidelines

• Mounting: Use industrial-grade cable management hardware to support the weight of the cable at 300 mm intervals. Avoid excessive tension during pull-through, as mechanical strain can alter the internal twist geometry and degrade signal characteristic impedance.

• Grounding: Bond the cable shield to the designated grounding rail at the FTA interface. A low-impedance path to the cabinet earth bus is mandatory to ensure the shield effectively redirects EMI to ground rather than allowing it to couple into the signal conductors.

• Wiring: Maintain strict physical separation from AC power leads and VFD high-power cables. A minimum separation distance of 150 mm should be observed for parallel runs to prevent inductive interference with the analog loop measurements.
