Features:

  • Signal Distribution Node Between the UCN Network Trunk and Field Instrumentation
  • Merges Multi-Port Cable Branching with Integrated Termination and Grounding Protection
  • Functions Within Honeywell TDC 2000, TDC3000, and TPS Distributed Control System Environments
The 51109693-100B serves as the 4-Port UCN Tap Kit in a Honeywell DCS network, providing reliable signal distribution and grounding management to all connected nodes across the Universal Control Network. It physically branches the UCN bus cable to support 2 to 4 connector ports and routes communication signals through the network backbone to enable steady state operation of all controllers, operator stations, and process I/O modules. Proper network termination is standard with the 51109693-100B, as the integrated terminators ensure signal integrity by preventing reflections at branch points. The 51109693-100B has made improvements in several areas over previous tap designs in addition to incorporating grounding protection within the UCN network architecture.

The 51109693-100B provides essential network connectivity functions common to the entire UCN segment, and is a critical component of the communication path, directly affecting the proper, normal operation of the overall control system. One or more 51109693-100B tap kits are required per UCN segment depending on the desired node count and physical layout. The 51109693-100B is typically mounted at strategic branching points along the UCN cable route to facilitate multi-point connections between the network trunk and field devices, occupying minimal physical space within the installation enclosure.

For expanded network applications, the UCN system requires additional 51109693-100B tap kits installed at subsequent branch points. In addition to standard single-tap operation, the distributed configuration also maintains proper signal distribution across all connected ports. The UCN network architecture executes communication routing using the integrated terminators built into the 51109693-100B design. Using this method, the network infrastructure ensures impedance matching across all branch points. If maintenance personnel determine that a network segment is no longer providing stable communication (outside configured impedance/tolerance levels), they can inspect the 51109693-100B terminators and grounding connections to restore proper network operation and record the corrective action in the system maintenance log.

The 51109693-100B Honeywell  4-Port UCN Tap Kit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

General

  • Manufacturer Honeywell
  • Model 51109693-100B
  • Condition New Original ready stock
  • Product Family 51402573-250,51404305-375,51201395-100
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • DCS Network Expansion: Used specifically in Honeywell TDC 3000 and Experion PKS (with UCN bridge) systems to expand the number of physical nodes on a single network segment.
  • Industrial Process Control: Deployed in environments requiring non-stop operation, such as Oil & Gas Refineries, Chemical Processing Units, and Power Generation Plants.
  • Signal Integrity Management: Applied in scenarios where long cable runs and multiple device connections risk signal degradation; the tap ensures clean branching and impedance matching.
  • Protocol Support: Designed for the UCN 5 Mbps Token Bus protocol, ensuring deterministic data exchange between controllers.
  • Multi-Port Branching: Provides 2 to 4-port connectivity, allowing the main UCN trunk (backbone) to "tap" into individual drop cables that lead to Process Managers (PM), Advanced Process Managers (APM), or High-Performance Process Managers (HPM).
  • EMI/RFI Protection: Serves as a Ground Tap, protecting the communication signal from electromagnetic interference and preventing ground loops that could lead to network-wide failures.
  • Mounting: Typically installed in marshalling cabinets or standard 19-inch racks where the UCN trunk cable is routed. Its compact footprint (12cm x 9.8cm) allows for dense installation.
  • Termination: The 51109693-100B often functions as a network endpoint or midpoint. It must be integrated with proper terminators (often part of the 51201395-100 kit) to prevent signal reflection.
  • Cabling Requirements: Requires high-quality coaxial drop cables. During installation, engineers must ensure the grounding screw is securely bonded to the cabinet's common ground bus to maintain the "Ground Tap" functionality.
  • Seamless Integration: As a passive electrical component, it does not require software configuration but must be physically verified during network commissioning using a signal analyzer to ensure low decibel (dB) loss across the ports.
Description
The Honeywell 51109693-100B is a specialized Ground Tap and Universal Control Network (UCN) Connector designed for high-performance industrial automation environments. As a critical component within the Honeywell TDC 3000 and Experion PKS ecosystems, the 51109693-100B facilitates reliable 2-4 port connections for UCN drop cables. 

This Honeywell 51109693-100B is specifically designed to handle the challenge of signal integrity and electrical grounding in complex Distributed Control Systems (DCS). In large-scale industrial plants, electromagnetic interference and improper grounding can lead to data corruption or hardware damage across the network. The 51109693-100B solves this problem by providing a dedicated, stable grounding point and a secure interface for UCN drop cables, ensuring that communication signals remain clean and consistent between the process controllers and the main network trunk.

In practical application scenarios, the Honeywell 51109693-100B is frequently deployed in oil refineries, chemical processing plants, and power generation facilities where continuous UCN uptime is mandatory. For instance, when expanding a control network to include new I/O modules, the 51109693-100B is used to tap into the existing coaxial bus, effectively managing the transition from the primary trunk to individual device drops. By utilizing the 51109693-100B, engineers can prevent impedance mismatches and reduce the risk of ground loops, thereby maintaining the overall health of the automation infrastructure.
