Honeywell 30731811-001

Product Introduction 30731811-001 is a dedicated LCN coaxial cable assembly for Honeywell TDC 3000 distributed control system. It transmits LCN local control network differential signals between TDC 3000 control nodes, operator stations and redundant network paths. It maintains characteristic impedance matching required for LCN 5Mbps communication. It comes with pre-terminated standard coaxial connectors at both ends. It is a standard replacement spare part for TDC3000 LCN network wiring.

Material Composition Solid copper inner conductor Foamed polyethylene dielectric insulation layer Copper braided shielding layer Flame retardant PVC outer jacket Nickel-plated brass coaxial connectors Internal crimp locking structure for connectors

Structural Features Integrated finished cable assembly with connectors fixed at both ends. Concentric coaxial structure separates signal conductor and shielding layer. Braided copper shield wraps dielectric layer fully to block external noise. Connector shell mates with standard LCN interface port on TDC3000 network boards. Outer jacket has smooth surface and printed part number marking. Connector tail has strain relief structure to prevent cable breakage under bending.

Working Principle LCN differential communication signal propagates along inner copper conductor. Braided shielding layer connects to equipment ground to isolate external electromagnetic noise. Impedance matching structure ensures signal wave transmits without reflection at connector interface. Signal attenuation is controlled within LCN network design budget to guarantee correct packet decoding at receiving node.

Installation Requirements Do not bend cable beyond minimum bend radius during installation. Align connector pin correctly before inserting into LCN port. Tighten connector nut by hand without excessive wrench torque. Arrange cable routing separately from high voltage power cable. Fix cable with cable tie without crushing outer jacket. Verify LCN network communication status after connection. Test redundant network switchover after cable replacement.

Usage Notes Do not cut or re-terminate the factory finished cable assembly. Avoid sharp object scratch on outer jacket. Do not pull cable by connector directly. Replace cable if shielding layer is exposed or connector pin is deformed. Keep cable away from high-temperature components inside cabinet.
