Emerson VE4003S2B1 – DeltaV S-series 2‑wide baseplate for modular I/O backplane integration

The Emerson VE4003S2B1 is a DeltaV S‑series 2‑wide baseplate designed to host and interconnect S‑series I/O hardware on the system backplane. From my experience, this carrier is the piece that quietly keeps things reliable—distributing 24 VDC and the DeltaV backplane signals between controller and I/O without fuss. You might notice that it’s often chosen for small expansions or phased upgrades, because it drops into existing S‑series enclosures with minimal wiring changes.

Key Features

• 2‑wide S‑series footprint – Hosts two S‑series module positions, ideal for compact expansions or localized I/O blocks.
• DeltaV backplane connectivity – Provides the system LocalBus/backplane path between controller and installed I/O for seamless data exchange.
• 24 VDC power distribution – Routes bulk power to the mounted I/O, simplifying cabinet wiring and keeping power organized.
• Drop‑in compatibility – Typically fits existing DeltaV S‑series panels and DIN setups without reworking the enclosure layout.
• Service-friendly layout – Clear module access for quick swap, which in many cases reduces process downtime during maintenance.
• Industrial temperature profile – Built for control cabinets in demanding plants; stable in typical process automation environments.

Technical Specifications

Application Fields

The VE4003S2B1 is typically used anywhere a DeltaV S‑series system is deployed: oil & gas terminals, chemical and refining units, life sciences skids, power generation balance-of-plant, and water/wastewater. One site lead at a midstream facility told us they like the 2‑wide carriers for “surgical” I/O additions—a few points at a time—without restructuring the entire cabinet.

Advantages & Value

• Form/fit/function for DeltaV S‑series – Keeps system architecture consistent and avoids custom mounting adapters.
• Faster turnaround – Small footprint means quicker cabinet work, which often cuts outage time during expansions.
• Lower lifecycle cost – Simplified power and backplane routing reduces wiring, documentation, and future maintenance effort.
• Risk reduction – Proven DeltaV backplane integration; seems to be the safest path when reliability and spares alignment matter.
• Technical backing – We support model checks, compatibility guidance, and pre‑shipment testing to de‑risk commissioning.

Installation & Maintenance

• Cabinet environment – Install in a clean, ventilated control enclosure; typical 0–55 °C, non‑condensing humidity. Allow airflow around modules.
• Mounting – DIN‑rail or panel mount per DeltaV S‑series layout practices. Maintain proper clearances for module extraction.
• Power & grounding – Feed 24 VDC bulk power through the recommended DeltaV distribution; follow star grounding and shield bonding guidelines.
• Wiring discipline – Separate power and signal bundles where applicable. Use proper ferrules and torque per manufacturer instructions.
• ESD & handling – Use ESD protection when inserting/removing modules. De‑energize circuits before service whenever possible.
• Routine care – Periodically inspect connectors, retighten terminals as needed, remove dust, and log firmware updates on connected I/O modules.

Quality & Certifications

• CE compliant; UL/cUL conformity applicable to DeltaV S‑series assemblies
• RoHS alignment for modern production runs
• Manufactured under ISO 9001 quality systems (Emerson)
• Warranty: 365 days (standard)

Recommended Related Components

For a smooth buildout, teams typically pair the VE4003S2B1 with DeltaV S‑series I/O modules, a compatible DeltaV controller, approved 24 VDC bulk power supplies, and the standard DeltaV terminal blocks. If you share your installed base list, we can sanity‑check part numbering to avoid mix‑and‑match issues.
