This is a passive backplane, not a powered module — it carries the rack’s power/data bus and holds CPU, I/O, and communication modules in their slots. Confirm slot compatibility against your specific CPU and module mix using Schneider’s Quantum system planning guide before ordering.
Product Introduction
The Schneider Electric 140XBP00600 is a six-slot rack backplane for the Modicon Quantum platform. It’s the physical rack chassis that carries the power/communication bus between the CPU and whatever local, remote, or distributed I/O modules you install in it — not a powered module itself, just the foundation everything else plugs into.
Techs pull this part when a rack physically fails (cracked connector, bent pins, corrosion) rather than any individual module in it. Since it’s passive, there’s no firmware, no protocol, and no configuration riding on it — swap it, reseat your existing modules, and the rack is back in service.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| One slot’s module won’t power up | Bad backplane connector pin at that slot | ✅ High | Visually inspect connector pins for bending/corrosion, try the module in a different slot | If the module works elsewhere, the backplane slot is suspect |
| Entire rack dead, no modules powering | Power supply module failure | ❌ Low | Check output voltage at the power supply module terminals | Replace/troubleshoot the power supply before the backplane |
| Intermittent faults across multiple modules | Loose module seating or backplane crack | ✅ High | Reseat all modules firmly, visually inspect backplane PCB for hairline cracks | Physical backplane damage usually means replacement |
| Single module faults, others fine | Module-level failure, not the rack | ❌ Low | Swap the suspect module into a known-good slot | Issue is likely the module, not this part |
| Rack won’t accept a specific module type | Wrong backplane variant for that module | ❌ Low | Check module’s slot/power requirements against backplane spec | Verify compatibility before assuming backplane defect |
If a suspect slot still won’t hold power after reseating and cross-testing, send us photos of the connector pins and a note on which slot is affected — that’s usually enough to confirm a backplane fault versus a module issue.
Frequently Asked Questions (FAQ)
Is this a powered module, or just a rack?
Just the rack. The 140XBP00600 is a passive backplane — it has no processor, no firmware, and nothing to configure. It carries power and bus signals between whatever CPU, I/O, and communication modules you install in its six slots.
Can I mix local, remote, and distributed I/O modules in the same backplane?
Yes. This backplane is rated for all three module categories, so you’re not locked into one I/O architecture per rack.
Do I need to reconfigure anything in my PLC program after swapping backplanes?
No. Since the backplane holds no configuration or firmware, your program, IP settings, and module configs stay with the modules themselves. Reseat them in the same slot positions and you’re back in service.
Is this a direct fit for my existing 6-slot Quantum rack?
If your current backplane is a 140XBP00600, yes — direct swap. If you’re working from a different XBP part number (4-slot, 10-slot, 16-slot variants), don’t assume interchangeability; slot count and physical mounting differ across the range.
Why is this cheaper than ordering new through Schneider?
Same reason as any New Surplus part — it’s sourced from decommissioned systems, cancelled builds, or excess OEM inventory rather than Schneider’s direct new-production channel. Functionally it’s the same backplane; you’re just not paying the new-channel markup.
What’s the warranty on this unit?
We back it with our standard warranty from the ship date. Schneider’s own contractual warranty on this part is 18 months from date of manufacture, for reference on OEM terms.
