Load distributions must be engineered so that the cumulative active current does not exceed this 3.0 A boundary.\u003c\/p\u003e\n\u003cp\u003eQ: Does the module require an external 24 VDC source to power the output loads?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The LocalBus only powers the internal logic and optical couplers of the module. All 32 high-side output channels require external field power supplied through the matching 32-channel terminal block.\u003c\/p\u003e\n\u003cp\u003eQ: How does off-state leakage current affect high-impedance field devices?\u003c\/p\u003e\n\u003cp\u003eA: The off-state leakage current is 1.2 mA maximum. For ultra-low power solenoid valves or high-impedance relays, this leakage current may prevent the device from dropping out. An external bleed resistor must be installed in parallel with such loads to shunt the leakage current.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModule Pin Alignment:\u003c\/strong\u003e Prior to inserting the card into the carrier slot, inspect the rear connector keys to ensure they align perfectly with the backplane socket before pressing down on the locking tab.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Block Compatibility:\u003c\/strong\u003e Always pair the VE4002S2T2B8 card with the standard 32-channel discrete output terminal block designated for Series 2 Plus architectures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShield Grounding Conductors:\u003c\/strong\u003e Connect the shield wires of all digital output field cables to the designated ground bus on the DeltaV carrier to minimize electromagnetic radiation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVentilation Clearance:\u003c\/strong\u003e Maintain at least 50 mm (2.0 in) of free space above and below the carrier rack to ensure natural convection cooling under high-ambient temperature conditions.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":48170710925502,"sku":"VE4002S2T2B8","price":650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-07-09_17-01-18_0ee517db-6b0b-483d-bfaa-99f5ece54a22.png?v=1784280378","url":"https:\/\/www.autooiltech.com\/ar\/products\/emerson-ve4002s2t2b8-deltav-discrete-output-card","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
