Emerson KJ3243X1-BK1 SE4022 12P4691X042: Maintaining PROFIBUS DP Connectivity in DeltaV S-Series Systems
For plants operating DeltaV S-Series systems, replacing a communication card requires careful attention to hardware identification, terminal arrangements and the existing field network. The Emerson KJ3243X1-BK1 SE4022 12P4691X042 listed by AMIKON is a PROFIBUS DP interface card for connecting compatible field devices to the DeltaV control system.
Its role becomes particularly relevant when maintenance teams need to restore an installed communication interface or support a modernization project that retains existing PROFIBUS equipment. Accurate selection starts with the complete product reference and continues through the installed system configuration.
01 / IDENTITY
The three identifiers in the product listing provide different information for purchasing and verification:
| Identifier | Meaning in the AMIKON listing | What buyers should confirm |
|---|---|---|
| KJ3243X1-BK1 | Hardware model | Complete model and installed hardware identification |
| SE4022 | Ordering reference for the simplex PROFIBUS DP interface arrangement | Whether the quotation includes the interface card and required terminal block |
| 12P4691X042 | Listed part-number reference | Exact agreement with the requested label or approved replacement specification |
Emerson’s published ordering information describes SE4022 as a simplex PROFIBUS DP I/O interface supplied with a termination block. This makes the scope of supply an important purchasing detail: a request for an individual replacement card and a request for a complete interface arrangement may require different quotations. Emerson ordering reference.
For an existing installation, send AMIKON a clear photograph of the full nameplate. Preserve 12P4691X042 exactly rather than shortening the enquiry to the base KJ model.
02 / SIGNAL PATH
The card provides the communication connection between compatible PROFIBUS DP field equipment and the DeltaV S-Series I/O subsystem.
A typical application involves distributed equipment whose process signals and operating status need to reach the control system. The engineering review should follow the complete path:
DeltaV controller and I/O subsystem → PROFIBUS DP interface → field network → compatible devices
Record the controller model, system release, carrier arrangement and existing card identification.
KJ3243X1-BK1 connects compatible PROFIBUS DP field equipment to the DeltaV S-Series I/O subsystem.
Review station addresses, communication settings and network drawings as part of the installed configuration.
GSD information describes communication rates, timing, available I/O and device features used for configuration.
Device configuration is an essential part of this connection. Emerson explains that a PROFIBUS device’s GSD file describes information such as supported communication rates, timing, available I/O and device features. DeltaV uses this information to configure communication with the device. Emerson PROFIBUS integration documentation.
For maintenance teams, this means a replacement enquiry should include the installed hardware reference and the relevant system records. Successful communication depends on the card, device configuration and network arrangement working together.
03 / SPECIFICATIONS
The Emerson instruction sheet for KJ3243X1-BK1 identifies the following electrical, environmental and installation characteristics:
| Parameter | Published specification |
|---|---|
| Product type | S-Series PROFIBUS DP interface card |
| LocalBus power rating | 12 VDC at 600 mA |
| Terminal-block key position | D3 |
| Parameter | Published specification |
|---|---|
| Ambient temperature | −40°C to +70°C |
| Relative humidity | 5–95%, non-condensing |
| Shock | 10 g, half-sine pulse for 11 ms |
| Vibration | 1 mm peak-to-peak at 2–13.2 Hz; 0.7 g at 13.2–150 Hz |
| Airborne contaminants | ISA-S71.04-1985 Class G3 |
| Parameter | Published specification |
|---|---|
| Calibration | Not required |
The instruction sheet also requires removal of system power and applicable field power before insertion or removal. Work should follow the referenced DeltaV installation documentation and the site’s approved procedures. Emerson KJ3243X1-BK1 instruction sheet.
These specifications help establish the installation requirements. The exact supplied unit, terminal arrangement and system compatibility still need to be checked against the project documentation.
04 / COMPATIBILITY
Record the controller model, system release, carrier arrangement and existing card identification. These details provide the basis for checking the proposed replacement.
Check its complete reference and required D3 keying arrangement. For a card-only replacement, establish whether the installed termination will remain in service.
Retain the device list, station addresses, GSD information, communication settings and network drawings. These records help engineers distinguish a hardware replacement requirement from a field-network or configuration issue.
SE4022 identifies a simplex ordering arrangement. Projects requiring redundancy should verify the documented hardware configuration, termination and software requirements before purchasing.
For procurement teams, including these details in the initial enquiry reduces uncertainty about what must be supplied.
05 / MODERNIZATION
PROFIBUS connectivity remains relevant in projects where plant operators want to retain serviceable remote I/O and field wiring while changing other parts of the control system.
Emerson’s November 2025 DeltaV IO.Connect documentation describes modernization approaches that retain supported Siemens remote I/O through PROFIBUS DP or PROFINET interfaces. This illustrates the continuing role of field-network integration in phased upgrades. The suitability of a particular KJ3243X1-BK1 SE4022 12P4691X042 unit must still be established for the specific project. Emerson DeltaV IO.Connect documentation.
Typical projects to evaluate include:
In each case, the installed network and approved engineering design determine the required hardware.
