Honeywell 51304540-200 LCNE2 Paddle Board

The Honeywell 51304540-200 LCNE2 Paddle Board is a communication interface board for the Honeywell TDC 3000 distributed control system. It is used to extend the Local Control Network (LCN) over fiber-optic links, enabling communication between local and remote network segments while supporting redundant A and B cable paths.

Key Features

• Designed for Honeywell TDC 3000 systems

• Extends LCN communications through fiber-optic connections

• Supports SMA fiber-optic connectors

• Independent A-path and B-path communication channels

• Channel-to-channel isolation to reduce EMI and ground loop effects

• CE-compliant LCNE2 version

Technical Specifications

Network Architecture

The LCNE2 Paddle Board is used to extend the Local Control Network to remote locations through fiber-optic cabling. A typical redundant installation uses four boards, with dedicated A and B communication paths at both ends of the fiber link.

Installation Considerations

The 51304540-200 is not hot-swappable. Removing or installing the board while the rack is energized may generate bus transients that can interrupt communications or damage hardware.

Frequently Asked Questions

Q: What is the main purpose of the 51304540-200 board?
