Product Details:

Schneider 140CRA31200 is a rack-mounted Ethernet RIO drop adapter module for Modicon Quantum PLC systems. This remote I/O adapter works with the 140CRP31200 head adapter to build distributed Ethernet RIO network architecture. It collects field I/O signals from the local Quantum rack and transmits data to the main CPU via EtherNet/IP and Modbus TCP protocols. The module supports daisy-chain and ring network topology, delivering stable real-time data exchange between remote I/O stations and the main control rack. Multiple LED status indicators clearly display module running status, network connection and I/O fault information for quick on-site inspection. Built-in self-diagnostic functions detect network disconnection, backplane and hardware faults, helping maintenance technicians rapidly locate system anomalies. Industrial hardware design offers good resistance to vibration and electromagnetic interference, suitable for continuous operation in power, petrochemical and manufacturing environments. Installed in standard Quantum rack slots, this adapter communicates with backplane and I/O modules to expand distributed control distance. Widely applied in process automation projects, this remote I/O accessory extends PLC control capacity, realizes decentralized field signal collection, reduces on-site wiring workload and supports reliable long-distance automation control.
