It provides signal coupling between the primary trunk cable and active node drop cables without requiring external electrical power. By maintaining strict insertion loss bounds below 0.25 dB, the physical assembly minimizes backplane bus communication velocity degradation and reflections across high-density drop configurations, ensuring deterministic packet timing and steady signal levels across all trunk segments.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the 1786-TPS\/C require external DC power to function on a ControlNet drop segment?\u003c\/p\u003e\n\u003cp\u003eA: No, the 1786-TPS\/C is a passive signal coupler that extracts power directly from the RF carrier signal present on the coaxial trunk line.\u003c\/p\u003e\n\u003cp\u003eQ: What coaxial cable specification must be paired with this tap module?\u003c\/p\u003e\n\u003cp\u003eA: The tap is engineered for impedance-matched operation with 75-Ohm RG-6 quad-shielded coaxial cable assemblies using standard BNC terminations.\u003c\/p\u003e\n\u003cp\u003eQ: How does insertion loss affect the maximum allowable number of taps per network segment?\u003c\/p\u003e\n\u003cp\u003eA: Each tap introduces an insertion loss under 0.25 dB. Total cumulative insertion loss must be calculated alongside total cable attenuation to remain within the ControlNet physical layer link budget limits.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eEnsure trunk cable segments are terminated with 75-Ohm trunk terminators at both physical end points of the ControlNet segment. Maintain minimum cable bend radii according to RG-6 coaxial standards during routing to prevent impedance shifts and signal reflection. Mount the tap assembly securely using a universal bracket or DIN-rail adapter to avoid mechanical strain on the BNC connectors. Verify that drop cable lengths between the tap and the device interface do not exceed maximum permitted ControlNet drop cable specifications.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":43757399343194,"sku":"1786-TPS\/C","price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4601\/3530\/files\/1786-TPS1.jpg?v=1785313927","url":"https:\/\/www.plcmasters.com\/products\/allen-bradley-1786-tps-c-controlnet-coaxial-t-tap","provider":"PLC Masters Ltd.","version":"1.0","type":"link"}
