Honeywell 08566200A Measurex Cable Assembly

Configured for signal path interconnection in Measurex automation platforms, the Honeywell 08566200A (08566200A Industrial Cable Assembly) provides direct physical execution of low-voltage electrical data transmission between Honeywell Measurex system components.

Hardware Specifications

Process Control and DCS Instrumentation Characteristics

• 4-20 mA HART loop protocol: The cable assembly is constructed to maintain the characteristic impedance required for signal fidelity in Measurex measurement loops. This ensures that the transmission of process variables remains within tolerance, preventing signal attenuation across the interface.

• Channel-to-channel isolation: The assembly utilizes multi-core shielding to maintain electrical separation between internal signal conductors. This architecture is necessary to mitigate crosstalk, ensuring that high-precision measurement signals are not corrupted by digital switching noise.

• Cold junction compensation (CJC): In applications where this assembly interfaces with sensor termination modules, the internal wiring geometry supports stable thermal conditions, facilitating consistent CJC performance by the downstream control hardware.

• FOUNDATION Fieldbus / Profibus PA connectivity: The assembly provides the necessary bandwidth and electromagnetic shielding required for fieldbus protocol communication, ensuring deterministic data exchange between Measurex measurement hardware and the central control system.

Frequently Asked Questions

Q: Is the 08566200A assembly compatible with all Measurex series hardware?

A: Compatibility is specific to the connector interface and signal requirements of the hardware. Always cross-reference the part number with your system’s installation manual or the Measurex equipment technical documentation prior to deployment.

Q: Does the cable shield require bonding to the cabinet ground?

A: Yes. For effective electromagnetic interference (EMI) suppression, the cable shield must be bonded to the instrument ground bus at the point of interface. Failure to properly ground the shield can lead to noise injection into the measurement signal.

Field Installation Guidelines

• Mounting: Secure the assembly using industrial-grade cable management to prevent tension on the connector junctions. Maintain a minimum bend radius of 6 times the cable diameter to preserve the integrity of the internal conductors and shielding.

• Grounding: Terminate the shield at the module ground lug to ensure a low-impedance path to the cabinet earth bus. This is mandatory for maintaining the assembly’s surge protection and noise-rejection performance.

• Wiring: Maintain strict physical separation from AC power leads and high-power VFD output cables. Use dedicated signal cable trays to ensure that the assembly remains isolated from inductive coupling, which is necessary to maintain measurement accuracy in industrial environments.
