Product Details：

Honeywell 51196694250 (51196694-250) is a longer version pre-terminated shielded coaxial cable assembly for Honeywell TDC3000 UCN universal control network,used for connecting NIM gateway modules,HPM controllers and UCN field nodes which require longer wiring distance inside control room or field cabinet. Compared with 51196694150,this cable is designed for longer transmission distance,while maintaining strict impedance matching consistent with UCN bus specification to reduce signal attenuation and high-frequency crosstalk. It adopts double-layer copper braided shielding structure,which can effectively resist interference from frequency converters,relay circuits and power lines in heavy industrial environment,avoiding packet loss,node dropout and communication instability on UCN bus. Both ends are pre-installed with dedicated coaxial connectors,plug and play directly without field crimping processing,greatly reducing poor contact faults during system reconstruction and spare replacement. It transmits real-time process data,control commands and node status feedback signals on UCN bus,cooperating with 51196692100 NIM network interface module to realize data interaction between LCN network and HPM controller rack. It has oil-resistant,anti-aging and flexible outer sheath,adapted to long-term operation in industrial cabinet environment. It is a rare original spare network cable accessory for legacy TDC3000 projects. When the original UCN trunk or drop cable is insufficient in length,insulation damaged or conductor broken,this cable can restore the communication link of the control layer network.

Key specifications：Pre-assembled shielded coaxial cable for TDC3000 UCN bus,impedance matched for UCN protocol,pre-molded dedicated connectors at both ends. Operating temperature range is 0°C to +60°C. It supports continuity and short-circuit continuity test for maintenance troubleshooting.

This UCN cable assembly is widely deployed in petrochemical,chemical,power generation and water treatment plants for legacy TDC3000 DCS cabinet layout adjustment,remote UCN node wiring and spare replacement projects. It cooperates with Honeywell NIM gateway board,HPM processor board and rack power supply to build complete LCN+UCN two-layer distributed control network. As a core unit for UCN long coax cable and network harness,it provides extended-distance signal transmission medium for TDC3000 universal control network. Clearly marked connector pins simplify rack wiring,network signal debugging and regular cable insulation aging inspection work for control engineers.
