The 140CRA93200 is a Remote I/O (RIO) Drop Adapter for the Modicon Quantum platform by Schneider Electric. It functions as the communication interface between a remote I/O rack and the central Field Control Station (FCS), enabling deterministic data exchange over a coaxial S908 RIO network.
By decentralizing I/O modules, the 140CRA93200 significantly reduces field wiring while maintaining reliable, high-speed communication. The module features dual female “F” connectors to support redundant coaxial topologies. If one cable path fails, the adapter automatically switches to the secondary path, ensuring uninterrupted process control.
Fully compatible with standard and specialty Quantum I/O modules, this drop adapter is widely deployed in distributed automation architectures across utilities, oil & gas, and heavy industry.

The 140CRA93200 is commonly used in:
Municipal wastewater and water treatment plants
Power generation facilities
Oil & gas processing sites
Large distributed manufacturing systems
It is particularly valuable in geographically dispersed installations where remote I/O racks are located across multiple buildings or process areas. In redundant architectures, it ensures continuous communication even if one coaxial cable segment is damaged.
Q1: How is the module address configured?
The address (01–31) is set using two decimal rotary switches on the module. The selected address must match the configuration in Unity Pro / EcoStruxure Control Expert or Concept software.
Q2: Does it support Ethernet RIO (eRIO)?
No. The 140CRA93200 is designed for traditional coaxial S908 RIO networks. Ethernet-based remote I/O requires different modules (e.g., CRA/CRP Ethernet series).
Q3: Can it be used in a Hot Standby system?
Yes. The 140CRA93200 is commonly used in Quantum Hot Standby architectures, ensuring remote I/O remains accessible to the active (Primary) processor.
