VE4002S2T2B8 Emerson 32-Channel Digital Output Module

Product Overview

The Emerson VE4002S2T2B8 is a high-density discrete output card engineered specifically for the DeltaV Series 2 Plus Distributed Control System (DCS). This module provides 32 independent high-side switching channels, delivering precise 24 VDC control signals to essential field equipment like solenoids, interposing relays, and status indicators. We supply this unit as 100% Brand New and Original, ensuring your critical process loops benefit from the latest hardware revisions and maximum MTBF (Mean Time Between Failures).

Technical Specifications

Engineering Advantages

• Granular Diagnostic Monitoring: The VE4002S2T2B8 tracks the health of every individual channel. This per-channel diagnostic capability allows the system to detect and report field-side faults immediately, significantly reducing troubleshooting time during unexpected outages.

• Optimized Space Efficiency: By packing 32 channels into a compact 41 mm wide form factor, this module maximizes I/O density within the DeltaV carrier. This reduces the total number of racks required and shrinks the overall footprint of your control cabinets.

• Hot-Swappable Design: The card supports full online replacement. Maintenance personnel can pull a faulty module and insert a brand-new VE4002S2T2B8 without powering down the carrier or interrupting the operation of adjacent I/O cards, maintaining continuous process uptime.

• Hazardous Environment Resilience: Built to withstand harsh industrial conditions, the module carries ATEX certification for Zone 2 locations. The wide operating temperature range (-40 C to +70 C) ensures stable performance in unconditioned field enclosures or extreme climates.

FAQs

• Can the VE4002S2T2B8 replace older DeltaV Series 1 discrete output cards?

  The VE4002S2T2B8 is optimized for Series 2 Plus hardware. While it maintains high-side switching logic similar to some older models, you must verify your specific carrier compatibility and DeltaV software version to ensure seamless integration.

• What type of field devices can this module drive directly?

  This module directly powers 24 VDC loads up to 100 mA per channel. It is ideal for driving small solenoid valves, LED indicator panels, and standard industrial control relays. For higher current loads, use an interposing relay.

• How do the per-channel diagnostics assist in maintenance?

  The module identifies open circuits or short circuits at the specific channel level. This information appears directly in the DeltaV Explorer or Diagnostic interface, allowing technicians to pinpoint the exact field wire or device causing the issue without manual point-to-point testing.

• Does this module require a separate field power terminal?

  The module receives 24 VDC through the bussed field power pins on the DeltaV I/O carrier. Ensure your power supply provides sufficient amperage to cover the combined draw of all 32 channels when active.
