Selection Guide
Use the following criteria to determine whether the 140CRA31200 is the right module for your application:
- Platform: Is your PLC a Modicon Quantum (140-series)? → Yes: proceed. No: consider BMXCRA31200 (M340) or BMECRA31210 (M580).
- Environment: Standard industrial environment? → 140CRA31200. Harsh/corrosive atmosphere? → 140CRA31200C (conformal coat).
- Redundancy Required? Single network path → 140CRA31200. Dual-ring / redundant Ethernet → 140CRA93200.
- Drop Count: Up to 31 RIO drops per Ethernet RIO network supported by the head-end adapter.
- I/O Module Slots: Up to 16 I/O slots per remote drop rack (depending on backplane selected).
- Fiber vs. Copper: 140CRA31200 uses copper RJ45. For fiber runs >100 m, use a media converter or select a fiber-capable variant.

Replacement & Compatibility FAQ
Q: Can I replace 140CRA31200 with 140CRA31200C?
A: Yes. The 140CRA31200C is a conformal-coated version with identical electrical and communication specifications. It is a direct drop-in replacement.
Q: Is 140CRA31200 compatible with Modicon M580?
A: No. The M580 platform uses BMECRA31210 or similar 580-series adapters. The 140CRA31200 is exclusive to the Quantum (140-series) backplane.
Q: Can I use 140NOE77100 instead of 140CRA31200?
A: Partially. The NOE module provides Ethernet communication but does not function as a remote I/O drop adapter. It cannot replace the CRA in a distributed I/O topology.
Q: What happens if the firmware versions mismatch between head-end and drop adapter?
A: Firmware mismatch can cause communication faults or prevent the drop from being recognized. Always align firmware versions across all CRA/CRP modules in the RIO network.
Q: Do you provide a warranty on surplus units?
A: Yes. Konmask.com offers a 90-day functional warranty on all refurbished and surplus units. New-in-box units carry the original Schneider Electric warranty.
Q: Can I order a single unit or do you require minimum quantities?
A: Single units are available. Volume discounts apply for orders of 3+ units. Contact us for a quote.
