Important: Do not rely on generic online specifications claiming 12 V DC, Modbus, CANopen, EtherCAT, or specific environmental ratings for this part. Those claims appear on a secondary listing but are not corroborated by the stronger part-number-specific references reviewed here.
Product Introduction
The ABB 086348-001 is a PWA7 ECF End Col Frame PC board associated with ABB / ASEA Brown Boveri ACCURAY equipment. Catalog records identify it as a VME-style board with two connectors, used as an end-column-frame board rather than a conventional PLC CPU or general-purpose I/O module.
This is an obsolete component, so the primary procurement concern is exact part-number matching and condition verification. Do not substitute a visually similar ABB board without confirming the board designation, connector arrangement, revision, and installed-system compatibility.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No system response after board installation | Board not seated correctly | ✅ High | Remove power, inspect connector engagement and board seating | Reseat only with power isolated |
| Intermittent system operation | Connector/contact problem | ✅ High | Inspect both connectors for oxidation, bent contacts, or mechanical damage | Clean/repair connector interface before condemning board |
| Board not recognized by system | Incorrect board or revision | ✅ High | Compare complete part number and PCB markings with removed unit | Match 086348-001 exactly before replacement |
| Existing fault remains after replacement | External system fault | ⚠️ Medium | Review system diagnostics and adjacent-board status | Check associated hardware before replacing another board |
| Visible corrosion or contamination | Storage/environmental damage | ✅ High | Inspect PCB, connectors, solder joints, and component leads | Do not install until condition is evaluated |
| Physical connector mismatch | Wrong part/revision | ❌ Low | Compare connector count and mechanical layout against original | Stop installation and verify part number |
| Board powers up but system remains faulty | Upstream/downstream equipment issue | ⚠️ Medium | Check related boards and system-level diagnostics | Isolate the fault before replacing additional hardware |
Technician’s warning: Don’t assume that a board that physically fits is electrically interchangeable. For an obsolete board such as 086348-001, photograph the installed board, connector positions, labels, and revision markings before removal. Then compare the replacement against those records.
If the fault remains unclear, provide the supplier with photos of the original board, complete nameplate/part-number markings, connector area, and diagnostic logs. That is much more useful than simply reporting “board failed.”
Frequently Asked Questions (FAQ)
Is ABB 086348-001 still manufactured?
Available part-number-specific sources identify 086348-001 as discontinued by the manufacturer. That means procurement normally depends on remaining original inventory, surplus stock, or professionally refurbished units.
What exactly is ABB 086348-001?
It is identified as a PWA7 ECF End Col Frame PC board. A repair catalog further describes it as a VME-style board, while another catalog specifies two connectors.
Is 086348-001 a PLC CPU?
No. The available part-specific descriptions classify it as a PC board / PWA7 ECF End Col Frame, not as a conventional PLC CPU. Calling it a generic PLC processor would be misleading.
Can I substitute another ABB board with a similar appearance?
I would not do that without documented compatibility. The board is obsolete, and the correct replacement decision should be based on the complete 086348-001 part number, board designation, connector arrangement, revision, and equipment configuration.
What condition should I specify when ordering?
Specify the condition explicitly: New Original / New Surplus, Never Used Original Packaging, or Refurbished / Tested. Do not accept the generic description “used” without asking for photographs and test information. Current market listings demonstrate that this part is sold in multiple condition categories.
Why can an obsolete 086348-001 cost substantially more than a normal PLC board?
This is a low-volume legacy spare rather than a current mass-market automation module. Remaining inventory is limited, and specialized repair/refurbishment services also list the part. Current listings show substantial price differences between unused and refurbished examples, which reflects condition and remaining availability rather than a standard new-production price.
What should I verify before placing a purchase order?
At minimum, verify 086348-001, PWA7 ECF designation, connector configuration, board revision/markings, physical condition, and the seller’s stated condition and warranty. For a production-critical replacement, request actual photos of the unit being shipped rather than relying solely on a catalog image.
