Product Introduction
The ABB P4LR 1KHL015107R0001 is a specialized ABB control-system board identified by the P4LR designation. Available records also associate the exact ordering code with RXRFP4LR, while other sources describe it simply as an ABB DCS/control board or network-partner component. Because the public documentation is inconsistent, the safest engineering description is a system-specific ABB control/interface board, rather than assigning it an unsupported PLC CPU, relay-output, or general-purpose I/O function.
For maintenance procurement, the complete number 1KHL015107R0001 should be treated as the primary identification. A board with the same P4LR designation but a different 1KHL ordering number should not automatically be considered interchangeable. One documented listing also associates this part with 1KHL015109P2 as a “network partner,” which is useful evidence that the board may form part of a larger proprietary ABB communication/control assembly rather than operating as a standalone PLC.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
The P4LR 1KHL015107R0001 is most appropriately considered a legacy ABB automation/control-system spare used within a larger proprietary control architecture. Its exact application should be determined from the cabinet BOM, adjacent boards, rack position, and equipment documentation. Public listings are particularly inconsistent: one source describes it as a DCS control board, another as a network partner, and others incorrectly attach modern computer-style processor and storage specifications.
Field checks before replacement:
- Match the full ABB number: Specify 1KHL015107R0001, not only .
- Confirm the parent system: Identify the exact ABB cabinet, rack, subassembly, or controller where the board is installed.
- Check the companion board: If the installed unit is paired with 1KHL015109P2, record that relationship before replacement.
- Do not assume generic PLC functionality: Available evidence does not establish this as a conventional PLC CPU or standard I/O module.
- Verify board revision: Compare PCB markings, connector layout, component population, and revision/date codes.
- Do not rely on unverified electrical data: Supply voltage, communication interfaces, I/O characteristics, and environmental ratings should come from the applicable ABB system manual.
- Preserve configuration information: If the board participates in a configured control or communications system, back up system parameters before replacement.
- Test the complete signal path: After installation, verify upstream/downstream communication and system diagnostics rather than judging the replacement only by power-up status.
