EMERSON VE4003S2B3 Analog Input Module

Product Overview

The Emerson VE4003S2B3 is an 8-channel 4–20 mA HART analog input module used in the Emerson DeltaV Distributed Control System (DCS). It is designed to acquire signals from field transmitters (pressure, temperature, flow, level) and convert them into digital values for process control.

It is a core DeltaV M-series I/O module, widely used in high-reliability industrial automation systems.
