Operating at the physical layer of the DCS architecture, the module routes communications between Field Control Units (FCUs) and human interface stations while maintaining impedance matching across the bus network. This physical isolation prevents noise propagation between network segments and maintains deterministic data transfer alongside 4-20 mA HART loop protocol subsystem networks.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What physical network protocol does the RS71*C module support?\u003c\/p\u003e\n\u003cp\u003eA: The module supports the proprietary Yokogawa V-net coaxial bus protocol, regenerating network signals between distributed Field Control Units.\u003c\/p\u003e\n\u003cp\u003eQ: How does the RS71*C maintain signal integrity across long coaxial cable segments?\u003c\/p\u003e\n\u003cp\u003eA: The module performs active wave-shaping and signal amplification to eliminate voltage attenuation and impedance mismatches across extended V-net bus segments.\u003c\/p\u003e\n\u003cp\u003eQ: What is the factory part number designation for the RS71C repeater module?\u003c\/p\u003e\n\u003cp\u003eA: The complete hardware part number designation for the RS71C repeater module is S9045BL-0.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eDe-energize system rack power before installing or servicing the RS71*C module. Observe electrostatic discharge (ESD) safety protocols by using a grounded wrist strap during card handling. Mount the module vertically into the designated CENTUM node rack slot, ensuring the backplane bus connectors seat fully before tightening top and bottom securing screws to maintain frame ground continuity. Terminate V-net coaxial cables using standard 75-ohm impedance connectors, ensuring proper grounding of outer cable shields at the cabinet entrance point. Maintain physical isolation between V-net communication cables and high-voltage AC power wiring to prevent electromagnetic interference.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":53278659281205,"sku":"RS71*C","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/RS71C.png?v=1786611763","url":"https:\/\/www.5gplc.com\/products\/rs71-c-yokogawa-centum-v-net-repeater-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
