Emerson VE4002S1T2B2 DeltaV S-Series Analog Input Module
Configured for high-resolution current loop processing in DeltaV S-series DCS platforms, the Emerson VE4002S1T2B2 (VE4002S1T2B2 Analog Input Module) provides direct physical/electrical execution. The 8-channel card converts incoming 4-20 mA field signals into digitized process variables via an onboard 16-bit analog-to-digital converter, routing primary values across the LocalBus backplane interface.

4-20 mA HART Loop Protocol and Channel-to-Channel Isolation
The VE4002S1T2B2 incorporates individual channel-to-channel galvanic isolation across all 8 input paths, preventing cross-channel ground loops and suppressing common-mode voltage spikes present in field cabling. The internal signal processing stack maintains transparent 4-20 mA HART loop protocol pass-through communication in point-to-point configurations. This enables secondary digital variable transmission, real-time diagnostic flags, and remote field instrument configuration updates to flow directly to DeltaV asset management tools without disturbing the primary analog measurement loop.
Frequently Asked Questions
Q: Can engineers hot-swap the VE4002S1T2B2 module on an energized DeltaV S-series carrier?
A: Yes. The hardware supports live removal and insertion under system power without interrupting adjacent I/O cards or corrupting backplane bus communications.
Q: How does the VE4002S1T2B2 power 2-wire field transmitters?
A: The module utilizes its bussed field power connection rated at 12 VDC at 300 mA alongside field circuit capabilities rated up to 24 VDC at 32 mA to energize external loops.
Q: What environmental protection is required when installing the card in Zone 2 locations?
A: Field panels must house the IP20-rated card inside an enclosure providing at least IP54 ingress protection to comply with ATEX and IECEx Zone 2 requirements.
Field Installation Guidelines
Align the VE4002S1T2B2 module with the carrier baseplate slot and push firmly until the locking mechanism latches into the backplane connector. Wire the 4-20 mA field loops to the corresponding terminal block terminals, separating low-level analog wiring from high-voltage power lines to eliminate inductive noise. Terminate cable shields at a single-point system earth bar near the cabinet entry point. Confirm cabinet ventilation maintains local ambient operating conditions within -40 to +70 deg C before applying system power.
