Product Overview
The Emerson VE4005S2B3 KJ3221X1-BA1 + KJ4001X1-CE1 Output Module with Terminal Blocks is an industrial process-control I/O assembly designed to provide an organized interface between a compatible Emerson automation system and connected field equipment. The assembly combines the KJ3221X1-BA1 output module with the KJ4001X1-CE1 terminal block, integrating the electronic I/O function with a dedicated field-wiring interface.
In modern process automation systems, output modules are responsible for transferring commands generated by the control system to field devices. Depending on the application and configured signal type, these devices may include control valves, actuators, positioners, process equipment, and other equipment requiring a controlled electrical command.
The terminal block provides an important connection point between the I/O electronics and field wiring. Combining the output module and terminal interface into one assembly can simplify cabinet organization, wiring identification, commissioning, troubleshooting, and maintenance.
The Emerson VE4005S2B3 has supplied dimensions of 107 × 41 × 105 mm and a weight of approximately 0.231 kg. Its compact physical format makes it suitable for industrial control cabinets and distributed I/O installations where space efficiency is important.
The exact electrical characteristics of the KJ3221X1-BA1 and KJ4001X1-CE1 combination, including channel configuration, signal range, electrical loading, isolation, resolution, accuracy, and terminal assignments, should be verified against the applicable Emerson documentation and hardware revision before engineering, installation, or replacement.

What Is the Emerson VE4005S2B3?
The Emerson VE4005S2B3 described here is an Output Module with Terminal Blocks consisting of the KJ3221X1-BA1 output module and KJ4001X1-CE1 terminal block.
The assembly provides a structured interface between an Emerson control system and external field circuits.
The output module performs the electronic I/O function, while the terminal block provides the physical termination interface for associated field wiring.
A simplified signal architecture is:
Controller → KJ3221X1-BA1 → KJ4001X1-CE1 → Field Wiring → Field Device
This arrangement provides a clear separation between control-system electronics and field-level wiring.
KJ3221X1-BA1 Output Module
The KJ3221X1-BA1 is the output-module component of the VE4005S2B3 assembly.
Its primary role is to interface controller-generated output commands with the field side of the automation system.
An output module can be used to communicate commands to compatible field equipment according to the configured control strategy.
For example, a process controller may calculate a valve command based on pressure, flow, temperature, or level feedback. The output module then provides the corresponding interface to the field circuit.
The exact electrical output characteristics must be confirmed from the applicable system documentation.
KJ4001X1-CE1 Terminal Block
The KJ4001X1-CE1 is the terminal-block component associated with the VE4005S2B3 assembly.
A terminal block provides an organized physical connection between the I/O module and field wiring.
This is especially useful in industrial control cabinets where numerous field circuits must be installed, identified, tested, and maintained.
The terminal interface can support maintenance activities such as:
- Field-wire inspection
- Loop testing
- Continuity checks
- Signal tracing
- Terminal verification
- Wiring replacement
- Fault isolation
The exact terminal assignment should always be verified using the applicable Emerson wiring documentation.
Function and Working Principle
The VE4005S2B3 works as part of a complete process-control system.
A representative control loop can be described as:
Process → Sensor → Input System → Controller → Output Module → Terminal Block → Field Device → Process
Process Measurement
Field instruments detect physical process conditions.
Typical variables include:
- Pressure
- Flow
- Temperature
- Level
- Equipment status
- Other process-specific measurements
Controller Processing
The controller compares process measurements with configured setpoints and executes the programmed control strategy.
Output Calculation
When a process adjustment is required, the controller calculates an appropriate output command.
Output Interface
The KJ3221X1-BA1 receives the output command and provides the corresponding field-side output interface.
Field Termination
The signal is routed through the KJ4001X1-CE1 terminal block and associated field wiring.
Field Device Response
The connected field device responds to the command.
Feedback
The resulting process condition is measured again, allowing the control system to continue regulating the process.
Role in Emerson Process Automation
The VE4005S2B3 serves as part of the I/O interface layer in a compatible Emerson automation architecture.
A modern process-control system may contain:
- Field sensors
- Transmitters
- Input modules
- Controllers
- Output modules
- Terminal blocks
- Control valves
- Actuators
- Drives
- HMI systems
- Engineering workstations
- SCADA platforms
The controller handles process logic, while the output assembly provides the physical connection to field equipment.
The combination of KJ3221X1-BA1 and KJ4001X1-CE1 therefore provides an organized path from control logic to field wiring.
Industrial Applications

The specific electrical requirements of the valve positioner must be confirmed before connection.
Chemical Processing
Chemical-processing facilities contain many automated control loops.
Output assemblies can interface with valves, actuators, dosing systems, and other equipment involved in chemical-process regulation.
Oil and Gas
Oil and gas facilities use distributed control and instrumentation for production, processing, storage, and utility systems.
Output modules can form part of the field interface for compatible control equipment.
Water and Wastewater
Water-treatment facilities use automated process equipment for:
- Flow control
- Pump control
- Chemical dosing
- Pressure regulation
- Level management
- Valve control
An output module with terminal interface can be incorporated into suitable Emerson control systems.
Power Generation
Power-generation plants require extensive process instrumentation and control.
Output I/O assemblies can support control loops involving valves, auxiliary systems, cooling equipment, pumps, and other process equipment.
Industrial Manufacturing
Manufacturing systems may require variable control of heating equipment, actuators, drives, valves, and other process devices.
The VE4005S2B3 can be integrated where the installed Emerson architecture supports the required output function.
System Integration
The VE4005S2B3 should be treated as one component within a complete industrial automation architecture.
A representative arrangement is shown below:
