Selection Guide
Use the following criteria to confirm the 140XCP51000 is the correct part for your application:
- ✅ You are using a Modicon Quantum backplane rack (140XBP series)
- ✅ You need to fill one single empty slot in the rack
- ✅ Your installation requires CE/UL compliance and EMC shielding continuity
- ✅ You want an OEM-original part for warranty and audit purposes
- ❌ If you need a functional I/O or communication module, refer to the 140ACI, 140ACO, 140NOE, or 140CRP series instead
- ❌ If your rack is M340 or M580, this module is not compatible — contact us for the correct blank module part number

Replacement & Compatibility FAQ
Q: Can I use any blank module in a Quantum rack?
A: Only modules with the correct Quantum single-slot form factor and backplane connector profile should be used. Using incorrect blanks may compromise EMC shielding and void CE/UL certification.
Q: Is the 140XCP51000 still in production?
A: Schneider Electric periodically updates its Quantum product lifecycle status. Contact Konmask.com for current availability and recommended alternatives if the part is end-of-life.
Q: Do I need to configure this module in Unity Pro / EcoStruxure Control Expert?
A: No. The 140XCP51000 is a passive mechanical component and requires no software configuration.
Q: Can one blank module replace another brand’s filler in a Quantum rack?
A: Yes, provided the third-party blank matches the Quantum slot dimensions and connector profile. OEM originals are always preferred for certified installations.
Q: What is the lead time?
A: In-stock items typically ship within 1–3 business days. Contact us for current stock status.
