The Emerson VE4003S2B1 (KJ3222X1-BA1 + KJ4001X1-CA1) is a DeltaV Series 2 analog input module designed for precise acquisition of 4–20 mA process signals in industrial automation systems. It is widely used to interface with smart field instruments such as pressure transmitters, temperature transmitters, flow meters, and level sensors, supporting both standard analog measurement and HART digital communication.
This configuration uses the KJ3222X1-BA1 analog input card together with the KJ4001X1-CA1 standard I/O termination block, enabling structured field wiring, simplified maintenance, and stable signal integrity in demanding process environments.
