The Emerson VE4005S2B2 (KJ3221X1-BA1 + KJ4001X1-CB1) is a DeltaV Series 2 Analog Output (AO) Module designed for precise control of field devices in industrial automation systems. It converts digital control signals from the DeltaV Distributed Control System (DCS) into 4–20 mA analog output signals for actuators, control valves, positioners, recorders, and other process control equipment. The module supports HART communication and includes a fused I/O termination block for enhanced field circuit protection.
