Honeywell 51202329-110 Violet Drop Cable

The Honeywell 51202329-110, also cataloged as the 51202329-110 Series C I/O Link Cable (Cable A), operates as a dedicated hardware component for localized data routing and multi-drop communication within Series C distributed control architectures.

Hardware Specifications

Process Control System Specifications

• 4-20 mA HART Loop Protocol Network Arbitration Alignment The multi-drop cable acts as the high-speed physical link layer that routes synchronized digital I/O data back to the primary C300 controllers. By preserving signal edge definition across the 6 network drops, it supports uncorrupted macrocycle execution rates for upstream 4-20 mA HART analog input cards and related safety infrastructure modules.
• Channel-to-Channel Isolation Performance and Signal Integrity The multi-drop assembly features high-density protective shielding designed to limit electromagnetic interference (EMI) and capacitive cross-talk within the cable bundle. This architecture maintains strict signal isolation parameters between processing channels, protecting the fieldbus communications from high-frequency electrical spikes generated by adjacent cabinet switching components.

Frequently Asked Questions

Q: What is the specific engineering purpose of the "Cable A" and "Violet" color designation?

A: In Honeywell Series C architectures, the violet jacket color paired with the Cable A designation identifies the primary data path of a redundant I/O link topology. It must be installed in parallel with a corresponding Cable B assembly to establish fully isolated, redundant communication routing.

Q: How does the fixed 6-inch pitch affect the mounting alignment of the Series C I/O modules?

A: The 6-inch (152 mm) pitch matches the physical layout of standard Series C input/output terminal blocks. This pre-engineered spacing allows plug-and-play installation straight down the vertical card rack, minimizing installation complexity and preventing excess cable loop accumulation.
