Product Overview
The Emerson SE4001S2T2B5 KJ4006X1-BP1 + KJ3203X1-BK1 DeltaV S-series Discrete Input Card Assembly combines a DeltaV S-series discrete input card with its associated carrier and terminal components to form an integrated field-input assembly.
Unlike a standalone I/O card, this assembly represents a broader hardware combination. The SE4001S2T2B5 provides the discrete input function, while the KJ4006X1-BP1 and KJ3203X1-BK1 form part of the physical interface and connection arrangement required to integrate the I/O point into the DeltaV system.
This configuration is particularly relevant when replacing an existing installed assembly rather than replacing only the electronic I/O card. Matching the complete assembly can simplify maintenance by preserving the intended relationship between the I/O module, carrier, and terminal interface.
For troubleshooting, engineers should distinguish between a fault in the input card itself and a problem involving field wiring, terminal connections, carrier hardware, or the connected field device. The complete signal path should be evaluated before replacing individual components.

Product Features
The assembly combines the electrical input function with the associated DeltaV mounting and field-connection hardware.
Key characteristics include:
- Emerson DeltaV S-series discrete input assembly
- Main I/O model SE4001S2T2B5
- Includes KJ4006X1-BP1 carrier component
- Includes KJ3203X1-BK1 terminal/interface component
- Intended for discrete field signal acquisition
- Provides an integrated connection path between field wiring and the DeltaV system
- Suitable for equipment-status monitoring
- Useful for alarms, permissives, and interlock-related signals
- Suitable for DeltaV system maintenance
- Practical for assembly-level replacement applications
The assembly format is important during replacement because the individual card and interface components form part of the same physical installation arrangement.
Working Principle
The assembly handles the transition from a physical discrete condition in the field to an input value that can be evaluated by DeltaV application logic.
A simplified signal path is:
Field Device → KJ3203X1-BK1 → KJ4006X1-BP1 → SE4001S2T2B5 → DeltaV Control System
The operation can be understood through several stages:
-
Field Device Changes State
A switch, relay contact, sensor, or other binary device changes its operating condition.
-
Field Signal Reaches the Terminal Interface
The electrical signal travels through field wiring to the applicable terminal/interface component.
-
Carrier and I/O Interface
The carrier hardware establishes the physical connection between the terminal arrangement and the discrete input card.
-
Discrete Input Acquisition
The SE4001S2T2B5 receives and processes the applicable discrete input condition.
-
DeltaV Processing
The acquired state becomes available to the DeltaV control application.
-
Application Response
Depending on the programmed strategy, the input can initiate an alarm, interlock, permissive, sequence transition, status indication, or other control action.
The complete relationship can be summarized as:
Field State → Terminal Interface → I/O Assembly → DeltaV Logic → Control Response
Role in a DeltaV S-series Control Architecture
This assembly occupies the field-interface portion of the DeltaV S-series architecture.
A practical arrangement can be represented as:
Field Equipment → Terminal Interface → I/O Assembly → DeltaV Controller → HMI / Supervisory System
Each component contributes a different function:
| Component | Function |
|---|---|
| SE4001S2T2B5 | Provides discrete input acquisition |
| KJ4006X1-BP1 | Provides the associated carrier/interface arrangement |
| KJ3203X1-BK1 | Provides terminal/interface connectivity |
| DeltaV Controller | Executes application logic |
| Field Devices | Generate discrete equipment states |
| HMI | Displays equipment and process conditions |
| Alarm / Interlock Logic | Responds to configured input states |
Using the assembly as a complete unit can be particularly useful when the existing installation has a defined card-to-carrier-to-terminal arrangement.
Industrial Applications
| Application | Typical Use |
|---|---|
| Oil and Gas | Monitoring valve and equipment states |
| Chemical Plants | Interlocks and process-status signals |
| Manufacturing | Machine-state acquisition |
| Water Treatment | Pump and valve monitoring |
| Power Generation | Equipment status inputs |
| Process Automation | Alarm and permissive conditions |
| Packaging Machinery | Sequence-related discrete inputs |
| Material Handling | Conveyor and equipment-state monitoring |
The actual channel assignment depends on the field instrumentation and DeltaV application configuration.
Installation and Maintenance
Because this product represents an assembly rather than a standalone electronic card, maintenance should include both the I/O hardware and its physical connection components.
Recommended practices include:
- Confirm SE4001S2T2B5 as the main I/O model.
- Verify KJ4006X1-BP1 carrier identification.
- Verify KJ3203X1-BK1 terminal/interface identification.
- Record the existing assembly position.
- Document field wiring and terminal assignments.
- Record channel-to-device relationships.
- Check the condition of terminal connections.
- Inspect the carrier and mounting arrangement.
- Check field cables for loose or damaged conductors.
- Verify the connected field device.
- Confirm the DeltaV I/O configuration.
- Follow the approved assembly replacement procedure.
- Ensure all connections are correctly seated.
- Check card diagnostics after installation.
- Verify representative input states.
- Confirm corresponding DeltaV application indications.
- Test related alarms, permissives, and interlocks where applicable.
- Record the completed maintenance configuration.
If a replacement assembly does not resolve the original fault, investigate the field device and wiring before assuming the electronic input card is defective.

Technical FAQs
Why would an engineer replace the complete SE4001S2T2B5 assembly instead of only the I/O card?
A complete assembly replacement can be appropriate when the existing installation requires the specific relationship between the I/O card, carrier, and terminal/interface components. It also reduces the risk of overlooking a damaged connection component when troubleshooting an assembly-level fault.
What should be checked if the input card appears healthy but the DeltaV signal is incorrect?
The troubleshooting path should move outward from the controller toward the field: verify the DeltaV configuration, input channel, carrier connection, terminal/interface wiring, field cable, and finally the field device. A healthy-looking I/O card does not prove that the correct electrical signal is reaching its channel.
How does the KJ3203X1-BK1 affect maintenance of the assembly?
The terminal/interface component forms part of the physical connection between field wiring and the I/O arrangement. Its terminals, wiring, and mechanical condition should therefore be included when investigating intermittent, missing, or unstable discrete input signals.
What is the best post-replacement test for this assembly?
A practical test should begin with card and system diagnostics, followed by verification of several representative field states. The corresponding DeltaV indications should then be checked, along with any application functions such as alarms, permissives, or interlocks that depend on those inputs.
