Honeywell 51200852-102 Data Communication Cable

The 51200852-102 is a dedicated data communication cable assembly from Honeywell, designed for high-speed digital signal interconnection and serial data frame transmission within High-Performance Process Manager and TDC 3000 platforms. This multi-conductor shielded cable assembly serves as a passive physical bus conductor, facilitating reliable point-to-point communication between field termination assemblies, multiplexer processing units, and control racks.

Shielding and Signal Integrity

The cable incorporates individually shielded twisted pairs to maximize channel-to-channel isolation and prevent external electromagnetic noise coupling across data lines. Precision differential signal conductors minimize crosstalk and signal distortion during high-frequency digital transmission. Furthermore, a high-dielectric outer insulation prevents ground loops caused by cabinet earth voltage differentials across distributed DCS racks.

Field Installation Guidelines

• Inspect male and female connector pin contacts for contamination or bent pins prior to mating with module sockets.
• Observe minimum cable bend radius limits along panel wireways to avoid internal conductor fatigue or shield tearing.
• Align connector keyways fully and hand-tighten locking thumbscrews to secure mechanical grounding.
• Separate data cable paths from AC high-voltage power conduits to eliminate inductive noise coupling.

Frequently Asked Questions

Q: Does the 51200852-102 data cable require external power or software configuration?

A: No, the cable is a passive physical inter-module bus assembly designed for direct point-to-point connection between compatible backplane interface headers.

Q: How is shielding handled across the cable connectors to protect against ground loops?

A: Cable shield drain wires tie directly to the connector strain-relief backshells to maintain single-point chassis grounding and high-frequency noise immunity.
