Product Overview
The Emerson KJ3002X1-BA1 DeltaV Analog Input HART Module is an analog input interface module used in Emerson DeltaV distributed control system (DCS) architectures. It provides the connection between field transmitters and the DeltaV control platform, allowing process measurement signals to be collected, converted, and transferred to the controller for monitoring and control.
The module is primarily used for integrating HART-compatible field devices, such as pressure transmitters, temperature transmitters, flow transmitters, and level instruments, into industrial process control systems. Through HART communication capability, the module can support both conventional analog signal acquisition and digital device information exchange.
Unlike standard discrete I/O modules, the KJ3002X1-BA1 focuses on continuous process measurement applications. It receives analog signals from field instruments, processes the input data, and provides the controller with accurate process information for regulatory control, monitoring, and operational decision-making.
The module is commonly installed in process industries where reliable analog measurement and intelligent field device management are required, including chemical plants, oil and gas facilities, power generation, and manufacturing process systems.

Working Principle
The Emerson KJ3002X1-BA1 operates as the interface between field transmitters and the DeltaV control system.
A simplified signal path is:
Field Transmitter → KJ3002X1-BA1 Analog Input HART Module → DeltaV Controller → Operator Station / Process Control
During operation, the module receives analog signals from connected field devices. The input signals are conditioned and converted into digital information that can be processed by the DeltaV controller.
For HART-enabled instruments, the module can also exchange digital communication information through the same field wiring, allowing access to additional device parameters and diagnostic information.
The module performs functions including:
- Analog signal acquisition
- Signal conversion
- Field device communication
- Transmitter data transmission
- Process variable monitoring
- Diagnostic information exchange
This allows the control system to maintain accurate process supervision while improving field device management capability.
Role in a DeltaV Control Architecture
The KJ3002X1-BA1 belongs to the field signal interface layer within an Emerson DeltaV DCS architecture.
A typical control structure can be represented as:
Process Sensor / Transmitter → Analog Input HART Module → DeltaV Controller → Engineering Station / Operator Interface
Within this architecture:
- Field transmitters measure process conditions.
- The analog input module receives and processes measurement signals.
- DeltaV controllers execute control strategies.
- Operator stations display process information.
- Engineering tools support configuration and diagnostics.
The module provides the connection point between physical process equipment and the digital control environment.
