Honeywell 51305072-700 TDC 3000 Input Output Board

The Honeywell 51305072-700, also cataloged as the CLCN-A/B I/O short face-plate PWA, operates as a dual-channel Local Control Network (LCN) interface card for Honeywell TDC 3000 and Experion PKS systems.

Hardware Specifications

Backplane Bus Communication and Profinet/EtherNet-IP Deterministic Networks

The 51305072-700 card provides deterministic backplane bus communication velocity across dual LCN paths (Cable A and Cable B). Integrated BNC tee connectors allow seamless insertion or removal of nodes without interrupting communication across active segments. The short face-plate variant is designed for secondary expansion rows, ensuring compatibility with multi-slot chassis assemblies. Electrical isolation up to 1500 VDC protects against industrial interference and fault conditions.

Frequently Asked Questions

Q: Can the 51305072-700 be disconnected while the LCN is live? A: Yes, the front-mounted BNC tee connectors allow hot-disconnection without disrupting communication across remaining nodes.

Q: What chassis slots are supported? A: The module fits standard 5-slot and 10-slot chassis assemblies, excluding Slot 1.

Q: How does the card achieve redundancy? A: Dual coaxial routing supports A/B channel redundancy, ensuring fault-tolerant communication.

Field Installation Guidelines

• Insert the card into designated chassis slots with full connector engagement.
• Ensure BNC tee connectors are properly seated and shielded to prevent signal reflection.
• Maintain grounding continuity for shielding layers to minimize electromagnetic interference.
• Route coaxial cabling separately from high-voltage conductors.
• Verify redundant A/B path integrity during commissioning before enabling system operation.
