The Honeywell 51305508-100, also known as the XLCNE2, is a specialized Local Control Network (LCN) extender paddle board designed for use within Honeywell TDC 3000 distributed control systems. This module functions as a fiber-optic interface to extend the LCN communication backbone, facilitating reliable, high-speed data exchange between controllers, I/O subsystems, and operator interfaces across extended distances.

Features

• LCN (Local Control Network) extender paddle board for TDC 3000 systems.
• Enables fiber-optic communication extension for distributed network architectures.
• Supports redundant A/B network configurations for high availability.
• Utilizes standard ST-type fiber-optic connectors for multimode fiber integration.
• Designed for backplane-mounted installation within system cabinets.

Applications

• Oil and Gas Refining: Facilitates communication between remote offshore or onshore hubs and central control rooms.
• Chemical Manufacturing: Supports real-time data transmission across large-scale production environments.
• Power and Energy: Enables synchronous data exchange between turbines, substations, and management grids.
• Municipal Water Systems: Connects remote pumping stations and reservoirs to centralized urban operations platforms.

Technical Specifications

Installation Guidelines

• Ensure the system is powered down before inserting or removing the paddle board to prevent electrical damage.
• Handle with care using ESD-safe practices to protect sensitive electronic components.
• When connecting fiber-optic cables, ensure the bend radius is maintained and cables are not pinched or sharply folded.
• Inspect and clean fiber-optic tips using appropriate optical cleaning kits prior to connection.
• Verify the optical power budget if communication links fail to establish; check fiber runs for potential faults or signal degradation.
• Note: This module is not backward compatible with legacy LCNE (51109881-100) or LCNE2 (51304540-100) boards.

FAQ

What is the primary function of the 51305508-100?

It acts as a network interface to extend the LCN communication backbone over fiber-optic links, allowing for greater physical separation between control nodes than is possible with standard copper cabling.

How many boards are required for a typical installation?

A standard redundant LCN extension typically requires four XLCNE2 boards: one for each A and B redundant fiber link at both ends of the network segment.

Is this module compatible with older LCNE versions?

No, the 51305508-100 is a replacement for the older LCNE and LCNE2 series but is not backward compatible with them. System-wide upgrades are generally required when transitioning to this model.
