Emerson DeltaV VE4005S2B2 (KJ3221X1-BA1) Analog Output Card

Product Description

The VE4005S2B2 is an Emerson DeltaV M-series 8-channel analog output card with HART support and fused termination, part number alias KJ3221X1-BA1. It outputs 4–20mA analog signals for valve positioners, actuators and field transmitters. The fused design provides individual channel overcurrent protection, improving field circuit safety and fault isolation. It plugs into DeltaV M-series I/O carrier and communicates over LocalBus to the controller.

Features

• 8 channels, 4–20mA analog output, HART protocol capable
• Fused I/O termination block version (differentiated from VE4005S2B1 standard type)
• High accuracy, suitable for continuous process control loop
• Hot swap supported for online replacement without system shutdown
• Diagnostics for open circuit, short circuit and fuse fault
• Operating temperature: -40°C ~ +60°C, CE / UL / FM certified
• Compact M-series form factor for DeltaV DCS rack

Applications

• Oil & gas, refining, chemical process DCS control
• Power plant, pulp & paper, water treatment automation
• Control of modulating control valves, I/P converters, actuators
• HART instrument integration for remote parameter configuration

FAQ

Q: What is the difference between VE4005S2B1 and VE4005S2B2?
A: VE4005S2B1 is standard termination; VE4005S2B2 is fused termination version with channel fuse protection.
