Product Introduction
The ABB PFVK135 3BSE007135R1 is a processor board used within the PFVA 131 Control Unit hardware assembly. ABB’s spare-parts information places PFVK135 together with the PFVK138 backplane, PFVI131 power-supply unit, PFVK134 signal processor board, and PFVO131 panel unit.
This is therefore a system-specific control board, not a conventional S800 I/O module, standalone PLC CPU, or general-purpose communication card. Replacement should be based on the complete PFVA 131 assembly configuration and the exact board identification.
Applications & Field Pitfalls — Engineer’s Perspective
The main procurement issue with PFVK135 is incorrect functional classification. Some secondary listings describe the part as an S800 I/O component, signal cable assembly, pulse-frequency input module, or generic controller. Those descriptions conflict with the ABB product-level identification of PFVK 135 as a Processor Board.
Typical Application Areas
- PFVA 131 control assemblies — processor-board replacement within the corresponding ABB control unit.
- Legacy ABB control-system maintenance — replacement of failed or degraded processor hardware.
- Industrial process equipment — maintenance of equipment incorporating the PFVA 131 control-unit architecture.
- Control-unit refurbishment — restoration of an existing assembly while retaining its original backplane, power, and signal-processing hardware.

Field Pitfalls
- Do not treat PFVK135 as a standalone PLC CPU. The documented product type is Processor Board, and it belongs to a larger PFVA 131 control-unit assembly.
- Check the complete part number. Verify PFVK135 / 3BSE007135R1 against the board marking and equipment BOM.
- Inspect the mating hardware. The associated PFVK138 backplane, PFVK134 signal processor board, PFVI131 power supply, and PFVO131 panel unit should be checked when troubleshooting the complete control unit.
- Do not assume S800 compatibility. The presence of ABB terminology in secondary listings does not establish that PFVK135 belongs to the S800 I/O platform.
- Exchange designation matters. ABB identifies the type designation as PFVK 135/EXCHANGE, so the exchange/replacement status should be retained in procurement records.

Procurement Note
Specify the component as:
ABB PFVK135 — 3BSE007135R1 — PFVK 135/EXCHANGE — Processor Board
For a replacement, the strongest verification is the 3BSE007135R1 product number plus the physical board marking. If the existing equipment is a PFVA131 control assembly, compare the processor board with the installed PFVK138 backplane, PFVK134 signal processor, PFVI131 power supply, and PFVO131 panel unit before approving the replacement.
ABB’s product-level data reports approximately 0.52 kg gross weight and identifies the item as a spare-part processor board.
Avoid publishing unsupported processor speed, memory size, communication protocol, operating voltage, or I/O-channel specifications for PFVK135 unless they are confirmed from the specific PFVA131 technical documentation or the board revision. The available product-level evidence does not establish those values.
