NETWORK ROLE
PROFIBUS DP
A dedicated interface between a DeltaV S-Series I/O architecture and a PROFIBUS DP field network.
|
LOCALBUS
12 VDC / 600 mA
The specified LocalBus power requirement for the KJ3243X1-BK1 card.
|
TERMINAL KEY
D3
Rotary keying is used to maintain compatibility between the card and its matching terminal block.
|
|
Fieldbus Connectivity
KJ3243X1-BK1 is the S-Series PROFIBUS DP card within the DeltaV I/O family. Its role is communication rather than conventional analog or discrete signal conditioning. The card provides one isolated PROFIBUS DP port for fieldbus communication.
|
System Placement
The card mounts in the assigned slot of an S-Series I/O carrier. The carrier provides the LocalBus connection and the system-side interface. PROFIBUS termination and field wiring are handled through the matching terminal arrangement.

|
01
Isolated PROFIBUS Interface
The interface separates the PROFIBUS communication port from the system-side circuitry, supporting the intended S-Series fieldbus architecture.
|
02
Carrier-Based Integration
The card is installed in an S-Series carrier, where the LocalBus supplies the card and provides the system-side connection.
|
03
Keyed Termination
The D3 rotary key position helps prevent an incompatible terminal-block/card pairing after installation.
|
| S-Series Model | Primary Role | How It Differs from KJ3243X1-BK1 |
|---|---|---|
| KJ3241X1-BK1 | Serial Card | Designed for serial-device communication rather than PROFIBUS DP networking. |
| KJ3242X1-BK1 | FOUNDATION Fieldbus H1 Card | Targets H1 Fieldbus connectivity; KJ3243X1-BK1 is the PROFIBUS DP interface. |
| KJ3243X1-BK1 | PROFIBUS DP Card | Provides one isolated PROFIBUS DP port; D3 terminal key; 12 VDC LocalBus supply, 600 mA maximum. |
| KJ3244X1-BK1 | DeviceNet Card | Provides DeviceNet connectivity rather than PROFIBUS DP connectivity. |
| KJ3231X1-BK1 | 4-Channel Isolated Input Card | Handles isolated analog-type input signals; it is an I/O signal card, not a PROFIBUS communication interface. |
| KJ3206X1-BK1 | 8-Channel 24 VDC Isolated DI | Processes discrete field inputs; it does not provide the PROFIBUS DP network interface. |
|
Power Planning
The LocalBus requirement is 12 VDC with a 600 mA maximum card current. For carrier loading calculations, the KJ3243X1-BK1 is specified at approximately 400 mA typical and 600 mA maximum.
|
Termination Matching
The D3 rotary key position is part of the card-to-terminal-block compatibility arrangement. Matching the terminal key to the installed card helps avoid an incorrect termination pairing.
|
|
Environmental Envelope
The specified ambient operating range is -40°C to +70°C. Relative humidity is 5–95% non-condensing, with ISA-S71.04-1985 Class G3 airborne-contaminant conditions specified for the card.
|
Service Handling
The card contains no user-serviceable parts and calibration is not required. System power must be removed before the card is inserted or removed.

|
|
Q1. Is KJ3243X1-BK1 the correct choice when an existing S-Series slot requires PROFIBUS DP?
Yes, when the required fieldbus is PROFIBUS DP and the existing architecture is compatible with the S-Series card family. KJ3243X1-BK1 is specifically the S-Series PROFIBUS DP interface card, while KJ3241X1-BK1, KJ3242X1-BK1 and KJ3244X1-BK1 serve different communication protocols.
|
|
Q2. What should be checked if a replacement KJ3243X1-BK1 does not match the installed termination?
Check the terminal-block key position before installation. KJ3243X1-BK1 uses the D3 key position. The rotary keying arrangement is intended to ensure that the card and terminal block are correctly matched.
|
|
Q3. How much S-Series LocalBus capacity should be reserved for KJ3243X1-BK1?
The card is rated for 12 VDC LocalBus power at 600 mA maximum, with approximately 400 mA typical current. Carrier power calculations should therefore account for the 600 mA maximum requirement.
|
|
Q4. Can KJ3243X1-BK1 be removed from the carrier while the system remains energized?
No. The specified handling procedure requires system power to be removed before inserting or removing the card. Field power supplied to the device, whether at the field terminal or through the carrier, must also be removed before the connection is disturbed.
|
|
Q5. Is KJ3243X1-BK1 suitable for an installation exposed to wide temperature variation?
Its specified ambient operating range is -40°C to +70°C. The card is also specified for 5–95% non-condensing relative humidity, 10 g half-sine shock for 11 ms, and the stated vibration and airborne-contaminant conditions.
