Emerson VE4003S2B6 DeltaV M‑Series 16‑Channel 2‑Wire HART Analog Input Card

Product Description

The Emerson VE4003S2B6 is a DeltaV M‑Series traditional I/O analog input card supporting 16 channels of 2‑wire 4‑20mA HART field transmitters. It is used in DeltaV distributed control systems to collect process measurement signals from pressure, flow, level and temperature transmitters. Integrated HART communication enables remote parameter reading, calibration and diagnostics. It supports hot‑swap operation and is widely used as spare part for petrochemical, refining and power plant DCS maintenance and system upgrade.

Product Functions

• 16‑channel 2‑wire 4‑20mA analog input for standard field transmitters
• Built‑in HART protocol support for remote device configuration and diagnostic data access
• Channel isolation and over‑range protection to reduce interference from field noise
• Hot‑swap capable, allowing card replacement without shutting down the DeltaV control node
• Real‑time signal conversion and data transmission to DeltaV controllers and operator stations
• Onboard self‑diagnosis, open‑loop and short‑circuit fault alarm reporting

Application Scenarios

• Petrochemical, refinery and natural gas DeltaV distributed control systems
• Thermal power plant boiler, turbine and auxiliary process control cabinets
• Chemical, pharmaceutical and water treatment continuous production process loops
• Offshore platform and pipeline process monitoring and control systems
• Spare replacement and repair of existing Emerson DeltaV M‑Series I/O racks
