It features integrated HART modems on every channel, allowing bidirectional super-imposed digital communications to pass transparently between host asset management software and field instruments like control valve positioners.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannel-to-Channel Isolation Parameters:\u003c\/strong\u003e Each current loop is optically and galvanically isolated from the controller’s logical backplane. This protects core processor components from ground differentials, field-side electrical surges, and line faults occurring on long field cabling paths.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFail-Safe State Execution:\u003c\/strong\u003e In the event of a LocalBus communication failure or controller CPU shutdown, each channel can be pre-configured via software parameters to hold its last state or ramp down to a predetermined safe value (typically 4.0 mA or 0.0 mA) to prevent erratic process upsets.\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 Does the VE4035S2B1 require an external power supply for the output loops?\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA:\u003c\/strong\u003e Yes. The module utilizes an external 24 VDC source connected to the terminal block to drive the active 4-20 mA current loops, while drawing separate low-power logic feeds directly from the carrier LocalBus.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ:\u003c\/strong\u003e Can this card be replaced while the process is running?\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA:\u003c\/strong\u003e Yes, the module supports hot-swapping. However, in non-redundant installations, pulling the card under load will break the 4-20 mA loops, immediately driving connected control valves to their fail-safe mechanical positions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ:\u003c\/strong\u003e How does the card signal an open-circuit loop fault?\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA:\u003c\/strong\u003e The module continuously monitors loop impedance. If a field wire breaks or disconnects, causing the loop current to drop below 3 mA, the module generates a channel-level open-circuit fault diagnostic that is propagated to the DeltaV alarm console.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Block Wiring:\u003c\/strong\u003e Strip the field loop wire insulation back by 6 mm before inserting them into the terminal block. Ensure the block is aligned perfectly with the card pins before pressing it into place.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShield Grounding Practice:\u003c\/strong\u003e Ground loop cable shields at a single point, preferably at the marshaling cabinet earth ground plate. Do not allow loop shields to contact ground at the valve positioner junction box.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow Clearances:\u003c\/strong\u003e Maintain a minimum of 50 mm convective clearance above and below the carrier rails to ensure natural air movement, preventing premature component aging due to stagnant thermal envelopes.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":48167443497150,"sku":"VE4035S2B1","price":650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-07-15_17-38-12_bf2cce67-2910-434a-a85d-18f20a658552.png?v=1784174558","url":"https:\/\/www.autooiltech.com\/products\/emerson-deltav-ve4035s2b1-output-card","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
