Honeywell 51109620-200 Shielded Cable Assembly

The Honeywell 51109620-200, also cataloged as the 51109620 Shielded Cable Assembly, operates as a dedicated hardware component for physical signal transmission within Honeywell distributed control system architectures. This factory-terminated multi-core harness provides direct physical and electrical conduction paths to route low-level analog and digital communications between control modules and peripheral field interfaces.

Hardware Specifications

Process Control Instrumentation and DCS Communication

The cable assembly employs a dual-layer electrostatic shield matrix to maintain high signal processing velocity across distributed control system networks. When routing sensitive 4-20 mA HART loop protocol parameters or high-frequency digital pulse data, the internal copper conductors are subjected to heavy external electromagnetic interference (EMI).

Frequently Asked Questions

Q: How does the integrated shielding system handle industrial electrical noise over the 20-foot cable span?

A: The cable utilizes a combined foil and braided shield configuration that achieves total coverage over the copper cores. The foil layer blocks high-frequency radio frequency interference (RFI), while the high-density braid provides structural durability and a low-resistance path for dumping electromagnetic induced currents to the system ground.

Q: Can this cable assembly be hot-swapped while the connected I/O modules are fully energized?

A: While the physical insulation is rated up to 300 V, hot-swapping depends entirely on the connected field hardware and signal type. Disconnecting active analog loops or digital control lines during live process execution will drop the telemetry stream instantly, which can trigger system faults or initiate fail-safe shutdown states within the host controller logic.
