Honeywell 51305072-100 LCN I/O Card
The Honeywell 51305072-100, also cataloged as the 51305072-100 Local Control Network I/O Card, operates as a dedicated hardware component for network node addressing and dual-coaxial signal interface management within Honeywell Experion and TDC 3000 LCN architectures. It manages physical data routing across LCN A and LCN B channels via onboard slide switches and hardware address logic.

Channel-to-Channel Isolation and Local Control Network Integrity
Designed for insertion into high-density DCS node chassis, the card provides galvanically isolated signal interface pathways between the dual Local Control Network channels (LCN A and LCN B) and the local node backplane. The hardware-based slide switch configuration fixes node addressing at the physical board level, maintaining deterministic token-passing communication cycles without software reliance. Integrated filtering and channel-to-channel isolation protect central node logic from network transients, preserving data throughput across 4-20 mA HART loop protocol networks and fieldbus interfaces tied to the system node.
Frequently Asked Questions
Q: How is the node address set on the 51305072-100 card?
A: Node addressing is established physically using the onboard slide switches prior to inserting the card into the chassis slot.
Q: What network connections are required for proper operation?
A: The card features dual coaxial connections for both LCN A and LCN B redundant network media cables to ensure continuous system communications.
Field Installation Guidelines
- Power down the host LCN chassis node or ensure proper live-insertion procedures are followed per Honeywell system guidelines before servicing.
- Set the designated binary/decimal node address using the onboard slide switches before sliding the card into the rack.
- Align the card edges with the cabinet slot guides and slide it in firmly until the backplane bus connector fully engages.
- Attach the LCN A and LCN B redundant coaxial cables to their respective BNC/coaxial connectors on the card front panel.
- Verify that coaxial cable shield grounding conforms to Honeywell single-point grounding rules to prevent ground loop noise on the LCN network.
