The Emerson SE4003S2B1 KJ3222X1-BK1 is an 8-channel analog input card for the DeltaV S-series control platform, handling 4–20 mA signals with HART communication.
In a typical process-control installation, transmitters located in the field continuously report variables such as pressure, flow, level, or temperature through current-loop signals. The SE4003S2B1 brings these measurement signals into the DeltaV control system, where they can be displayed, alarmed, recorded, and used by control strategies.
The KJ3222X1-BK1 designation is associated with the SE4003S2B1 hardware configuration. The combination is commonly encountered when identifying S-series I/O hardware for system maintenance, replacement, or inventory management.
An 8-channel arrangement allows multiple field loops to be handled within the same I/O section, making the card applicable to distributed transmitter connections in process plants.

The SE4003S2B1 receives analog current signals from field transmitters and makes the measured information available to the DeltaV control system.
A common signal path is:
Process Variable → Field Transmitter → 4–20 mA Loop → SE4003S2B1 → DeltaV Controller → Control / Monitoring Application
For example, a pressure transmitter may convert the measured process pressure into a 4–20 mA signal. The input card receives the current-loop signal and transfers the measurement into the DeltaV system.
Where HART communication is used, the same field loop can also carry digital device information in addition to the primary analog measurement. This allows the control system to work with both the process variable and applicable transmitter information.
The resulting measurement can be used for:
The SE4003S2B1 sits on the measurement side of the DeltaV control architecture.
| System Element | Function |
|---|---|
| Process Equipment | Produces the measured process condition |
| Field Transmitter | Converts the physical variable into a measurement signal |
| 4–20 mA Loop | Carries the analog measurement |
| SE4003S2B1 | Acquires the analog input |
| DeltaV Controller | Processes the measurement |
| Control Application | Uses the value for control and monitoring |
| Operator Station | Displays process information |
| Historian / Supervisory Layer | Stores and analyzes process data |
The quality of the final process value depends on the complete measurement path, including the transmitter, loop wiring, termination, input channel, and DeltaV configuration.
The card can collect transmitter signals associated with pressure, flow, level, and other continuously measured process variables.
Typical applications include monitoring reactor conditions, vessel levels, pipeline pressure, and process flow.
Analog measurements from plant instrumentation can be brought into the DeltaV system for equipment monitoring and process regulation.
The input channels can be used with process transmitters measuring flow, pressure, level, and other plant variables.
Applications include monitoring process equipment and integrating analog transmitter measurements into automated production systems.
Correct loop identification is important when working with an analog input card because each channel may correspond to a specific process transmitter.
Recommended maintenance practices include:
An incorrect process value should not automatically be attributed to the input card. The transmitter, loop power, wiring, termination, channel configuration, and process instrument itself should all be considered during troubleshooting.

The card is intended for 4–20 mA analog field signals and can be used with process transmitters that communicate measurement information through this current-loop format. HART-enabled devices can also use the digital communication layer associated with the loop.
The 4–20 mA signal carries the primary analog measurement, while HART can carry additional digital information from the field device. This can be useful for device-related information, configuration, and diagnostics without replacing the basic current-loop measurement.
Start by checking whether the transmitter output changes with the actual process condition. Then check loop power, wiring, termination, input-channel status, and DeltaV configuration. A fixed value can originate from either the field instrument or the signal path rather than the input card alone.
Compare the transmitter’s actual loop output with what reaches the corresponding input channel. If the transmitter produces the expected signal but the DeltaV value is incorrect, attention should shift toward the wiring, termination, input hardware, or configuration. If the transmitter output itself is incorrect, the investigation should begin at the field instrument.
