Schneider Electric 140CRA31200 Ethernet RIO Drop Adaptor

Product Overview

The Schneider Electric 140CRA31200 delivers reliable Ethernet-based RIO communication for the Modicon Quantum automation platform.
Moreover, this RIO drop adaptor supports a single Ethernet channel while ensuring stable data exchange across distributed I/O architectures.
Additionally, Schneider Electric integrates Ethernet IP and Modbus TCP protocols to simplify network standardization and system scalability.
Therefore, the 140CRA31200 fits automation systems requiring deterministic Ethernet communication with compact mechanical dimensions.

Application and Performance

First, the 140CRA31200 connects remote I/O drops using Ethernet while maintaining daisy chain loop network topology.
Next, the adaptor operates consistently within industrial cabinets thanks to its IP20-rated enclosure design.
Furthermore, the module handles high-humidity environments up to ninety-three percent without performance degradation.
Consequently, system designers achieve stable communication across demanding industrial automation installations.

Mechanical and Environmental Design

Notably, the 140CRA31200 uses a rack-mountable form factor to streamline installation inside Modicon Quantum control racks.
In addition, the compact housing measures approximately 6.6 inches wide and 2 inches high.
Likewise, the lightweight structure, weighing about 0.91 kilograms, simplifies handling during maintenance and upgrades.
Meanwhile, the adaptor operates reliably between 0°C and 60°C under continuous industrial workloads.
