Schneider Electric 140CRA31200 EtherNet/IP Remote I/O Adapter – Modicon Quantum Series
When a Modicon Quantum PLC loses communication with its remote I/O drops, the consequences cascade instantly — production lines halt, safety interlocks trip, and maintenance teams scramble to diagnose a fault that could have been prevented with the right adapter module. The Schneider Electric 140CRA31200 is the purpose-built EtherNet/IP communication adapter that keeps Quantum remote I/O drops reliably connected to the control network, eliminating that single point of failure in mission-critical automation architectures.
Within the Modicon Quantum family, the 140CRA31200 occupies a strategic position as the standard single-channel EtherNet/IP RIO drop adapter. It bridges the Quantum backplane to a standard 10/100 Mbps EtherNet/IP network, enabling deterministic I/O scanning over the same Ethernet infrastructure used for HMI, SCADA, and enterprise data — a topology that has become the global benchmark for scalable, open industrial automation.

Frequently Asked Questions
Q: What is the difference between 140CRA31200 and 140CRA93100?
A: The 140CRA31200 uses EtherNet/IP as its network protocol, while the 140CRA93100 uses Modbus Plus. They are not interchangeable — your CPU and network infrastructure must match the adapter protocol.
Q: Can the 140CRA31200 be used with Modicon M340 or M580 CPUs?
A: No. The 140CRA31200 is exclusively designed for the Modicon Quantum backplane architecture. For M580 distributed I/O, Schneider Electric offers the BMECRA31210 EtherNet/IP adapter.
Q: How many I/O modules can one 140CRA31200 drop support?
A: A single RIO drop can support up to 16 I/O module slots depending on the backplane selected (e.g., 140XBP01600 = 16 slots).
Q: Is the 140CRA31200 still in production?
A: Schneider Electric has transitioned the Quantum platform to a mature/maintained status. The 140CRA31200 remains available as a spare part. Contact us to confirm current stock and lead times.
Q: What firmware version does the 140CRA31200 ship with?
A: Firmware versions vary by production batch. Please specify your Unity Pro / Control Expert version when enquiring so we can advise on compatibility.
