EMERSON VE4003S2B2 – DeltaV S-series 4–20 mA HART Analog Input Module (8 channels)

The EMERSON VE4003S2B2 is a DeltaV S‑series analog input module designed for plants that rely on 4–20 mA loops and want native HART diagnostics inside DeltaV. From my experience, this model is typically selected for brownfield replacements and capacity expansions where you need eight reliable AI channels on a single card while keeping HART device data accessible for maintenance and asset health.

You might notice that it fits into standard S‑series I/O carriers and supports hot‑swap in most configurations, which keeps downtime tight during a swap. A customer in a chemical blending unit told us they dropped it in place to restore a failed AI bank and immediately recovered HART pass‑through without touching their controller configuration—exactly the kind of low‑risk change operations teams prefer.

Key Features

• Eight 4–20 mA AI channels: Consolidates common process inputs (pressure, flow, level, temperature transmitters) on one card.
• Native HART support: Pass‑through diagnostics for device status, PV, and configuration—very handy for proactive maintenance.
• DeltaV S‑series integration: Seamless diagnostics in DeltaV Explorer; typically zero extra middleware.
• Hot‑swap capability: Swap the module on a powered carrier in most cases, reducing downtime during maintenance.
• Flexible field wiring: Works with standard S‑series terminal blocks; neat for mixed 2‑wire and 4‑wire transmitter loops.
• Proven reliability: Designed for control room environments; stable readings and robust channel health reporting.

Technical Specifications

Related or Supporting Products

• EMERSON VE4003S2B1: Similar S‑series AI module variant; often used as a direct spare in earlier systems.
• EMERSON VE4003S2B3: Later hardware revision in the same family; check channel specs and certifications before mixing.
• EMERSON S‑series terminal blocks (AI): Matching field‑wiring blocks for 2‑wire/4‑wire transmitters.
• DeltaV S‑series I/O carrier: Required backplane for module installation; ensure slot availability and proper keying.

Installation & Maintenance

• Cabinet & environment: Mount in a clean, dry control cabinet; typical ambient 0–55°C with adequate ventilation. Keep clearance for airflow and service access.
• Wiring: Use shielded twisted pairs for 4–20 mA loops. Land shields per site EMC practice. Verify loop power (2‑wire vs 4‑wire) and polarity before commissioning.
• Grounding & EMC: Bond cabinet ground to plant earth; separate high‑voltage cabling from low‑level analog signals to minimize noise.
• Hot‑swap: In most cases, modules can be replaced live on powered carriers—confirm with MOC and follow site procedures to avoid nuisance alarms.
• Routine checks: Periodically verify channel health in DeltaV diagnostics, clean dust from cards and vents, and review HART alerts for early device issues.
• Calibration: Loop calibration is typically done at the field transmitter; trend AI values after maintenance to confirm stability.
• Firmware/Hardware compatibility: Before mixing revisions, check DeltaV release notes so the module hardware aligns with your system version.

Quality & Certifications

• CE compliant
• UL/cUL recognized (typical for DeltaV S‑series modules)
• RoHS conformity for electronics, where applicable
• Manufacturer’s standard warranty practices apply; sales warranty provided is 365 days

If you’re replacing an installed card, share your current DeltaV version and the existing module revision. It seems to save a lot of time matching firmware and terminal block layouts, and in many cases we can cross‑check the exact spare you need before you place the order.
