This digital trunk allows the host controller to continuously poll up to 32 total field transmitters or positioners across its two independent ports.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannel-to-Channel Isolation Parameters:\u003c\/strong\u003e To maintain robust execution under electrical line faults, the module features built-in galvanic isolation of 1500 VDC. This barrier prevents destructive ground loop currents and high-energy transients on the field bus from migrating into the central processing backplane.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1:1 Redundancy and Automatic Switchover:\u003c\/strong\u003e Supports seamless 1:1 redundancy when deployed on a redundant carrier assembly. The passive terminal block links two identical interface cards, providing continuous autosensing and automatic bumpless switchover of active communication states if a primary hardware fault occurs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ:\u003c\/strong\u003e What is the maximum physical device capacity per H1 port on this card?\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA:\u003c\/strong\u003e Each of the two ports can physically address up to 16 multi-drop devices, for a total of 32 devices per card. However, actual design limits depend on segment power supply capability, cable length, and overall loop execution latency requirements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ:\u003c\/strong\u003e How does the card handle power distribution to the H1 field segments?\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA:\u003c\/strong\u003e The VE4017 interface card does not supply power directly to the H1 trunk. External, dedicated FOUNDATION Fieldbus power supplies and impedance matchers (conditioners) must be integrated into the segment wiring topology.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ:\u003c\/strong\u003e Is a redundant terminal block required to achieve 1:1 hardware redundancy?\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA:\u003c\/strong\u003e Yes. To implement a fully redundant H1 segment, a redundant terminal block must be combined with two active VE4017 interface modules. This allows the secondary card to instantly monitor and take over communication without dropping fieldbus packets.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSegment Termination Verification:\u003c\/strong\u003e Every H1 field segment requires exactly two physical terminators, typically located at the power conditioner and at the furthest junction box in the field. Operating a segment with incorrect termination will cause severe wave reflections and communication failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShield Grounding Continuity:\u003c\/strong\u003e The H1 cable shield must be continuously connected through all field junctions but grounded at only one central point—typically at the H1 power conditioner cabinet. Do not ground the cable shield at the individual transmitter housings to prevent parallel ground loop paths.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModule Insertion and Latching:\u003c\/strong\u003e Align the card with the designated M-series carrier guide rails. Slide the card back until the pin connectors seat completely into the backplane, then hand-tighten the top and bottom retaining screws to secure the module against vibration.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":48167442448574,"sku":"VE4017","price":650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-07-10_10-58-30_9ba143c5-e91a-4954-b9fb-2db4613e1625.png?v=1784174442","url":"https:\/\/www.autooiltech.com\/ar\/products\/emerson-ve4017-deltav-fieldbus-h1-card","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
