Product Overview
The Honeywell XLCNE2 (Part Number: 51305508-200) serves as a high-speed Local Control Network (LCN) extender paddle board designed specifically for Honeywell TDC 3000 and Experion PKS control systems. It facilitates seamless, high-integrity fiber optic communication over extended physical distances, bypassing the length limitations of standard coaxial cabling. By utilizing light-based transmission, the XLCNE2 eliminates electromagnetic interference (EMI) risks, ensuring that critical process data remains stable across large-scale industrial facilities.

Engineering Advantages
-
Long-Distance Signal Integrity: The XLCNE2 overcomes the 300-meter copper limit, allowing control systems to span kilometers via fiber. This capability supports distributed plant architectures without requiring intermediate signal repeaters.
-
EMI/RFI Immunity: Because fiber optic cable carries light rather than electrical current, the XLCNE2 provides absolute immunity to lightning strikes, high-voltage surges, and radio frequency interference commonly found in refinery and power plant environments.
-
Optimized Redundancy Path: A standard LCN extension utilizes four XLCNE2 boards (two at each end) to support both A and B communication cables. This configuration ensures that a single fiber break never disrupts the control network.
-
Simplified Maintenance: The use of industry-standard ST-type connectors ensures a secure, "twist-and-lock" mechanical connection. This minimizes signal attenuation caused by vibration and simplifies field testing with standard fiber optic diagnostic tools.
FAQs
Q: Is the XLCNE2 compatible with legacy LCNE or LCNE2 boards?
A: No. The XLCNE2 (51305508-200) features updated internal circuitry and is not backward compatible with older LCNE or early LCNE2 models. You must replace all boards in an extension string with the XLCNE2 version to ensure successful network synchronization.
Q: Is this unit 100% Brand New and original?
A: Yes. We supply only 100% Brand New and original Honeywell factory equipment. Every unit arrives in factory-sealed packaging with a full 12-month industrial warranty.
Q: Why do I need four boards for a single LCN extension?
A: Honeywell architecture requires redundancy for safety-critical control. You place two boards at the local node (one for Cable A, one for Cable B) and two boards at the remote node. This ensures that the network survives a failure of either the A or B fiber link.
Q: Does the XLCNE2 require specialized configuration software?
A: The board functions as a hardware-layer interface. Once correctly jumpered and installed into the LCN rack, the TDC 3000 or Experion system recognizes the fiber link automatically. Always verify your LCN node addressing after installation.
