Information About 51305072-200
The 51305072-200 functions as the paddle board interface for LCN Cable A in Honeywell’s Total Plant Network (TPN) systems, forming part of the dual redundant Local Control Network (LCN) configuration. Cable A connects through this board, while Cable B is connected via a separate CLCN-B paddle board in the same chassis. The board includes BNC tee connectors that allow a node to be disconnected from the coaxial segment without interrupting communication between other nodes. Cable A is identified with yellow shrink-fit bands, and the LCN supports up to seven coaxial segments, including a central segment and up to six remote nodes. When extended with LCNE2/XLCNE2 fiber optic extenders, the system provides ground isolation and supports communication in hazardous areas.
Key Features:
-
LCN Cable A Interface: Serves as the connection point for LCN “A” cable in dual-node Honeywell control systems.
-
BNC Tee Connectors: Enable node disconnection without affecting communication on the rest of the segment.
-
Redundant Communication Support: Works in conjunction with CLCN-B paddle board for dual-path LCN redundancy.
-
Coaxial and Fiber Optic Integration: Supports extension with LCNE2/XLCNE2 modules for hazardous or remote areas.
-
Segment Connectivity: Allows up to seven coaxial segments (one central and up to six remote) in the LCN.
-
Color-Coded Cabling: Yellow shrink-fit bands identify Cable A, ensuring correct installation and maintenance.
-
Industrial-Grade Design: Built for continuous operation in demanding process control environments.
-
Lightweight and Compact: Weighs only 0.35 lbs for easy installation in existing chassis.
The 51305072-200 delivers the connectivity and redundancy required for reliable communication within Honeywell’s LCN-based control networks.
