Remote I/O Automation Solution – Schneider Electric 140CRA31200C | Modicon Quantum Series
Where This Product Is Used
The Schneider Electric 140CRA31200C is a Modicon Quantum RIO (Remote I/O) Drop Cable Adapter Module designed for distributed control architectures in demanding industrial environments. Engineers specify this module wherever a Quantum PLC head-end must communicate with remote I/O drops over a coaxial RIO cable backbone.
Typical deployment sites include:
- Oil & Gas Facilities – Wellhead control panels, pipeline SCADA nodes, and compressor station automation where long-distance I/O extension is required.
- Water & Wastewater Treatment Plants – Pump station remote monitoring, chemical dosing control, and distributed sensor networks across large plant footprints.
- Power Generation & Utilities – Substation automation, turbine control auxiliaries, and distributed protection relay interfacing.
- Automotive & Heavy Manufacturing – Assembly line I/O extension, robotic cell integration, and conveyor system control.
- Chemical & Pharmaceutical Plants – Batch process control, reactor monitoring, and safety instrumented system (SIS) I/O expansion.
- Building Automation & Infrastructure – Large-scale HVAC, access control, and energy management systems requiring distributed I/O over long cable runs.

Why Engineers Specify This Model
- Proven Quantum Platform Compatibility – The 140CRA31200C is a native Quantum-series component, ensuring seamless integration with existing Quantum CPU racks, power supplies, and I/O modules without gateway or protocol conversion overhead.
- Long-Distance I/O Extension – The RIO coaxial bus supports cable runs up to 3 km (with repeaters), making it the preferred choice for geographically distributed plant layouts.
- High Noise Immunity – Coaxial RIO architecture provides superior EMI/RFI rejection compared to twisted-pair alternatives, critical in high-voltage switchgear rooms and VFD-dense environments.
- Deterministic Scan Cycle – RIO drops maintain deterministic I/O update times, essential for time-critical process control and safety applications.
- Simplified Wiring – A single coaxial drop cable connects the adapter to the RIO trunk, reducing field wiring complexity and commissioning time.
- Hot-Standby System Support – Compatible with Quantum Hot Standby CPU configurations for high-availability control architectures.

Application-Specific FAQ
Q: Is the 140CRA31200C compatible with all Modicon Quantum CPU models?
A: Yes. It is compatible with all Quantum-series CPUs that support the RIO bus, including 140CPU311, 140CPU434, 140CPU651xx, and Hot Standby variants. Verify your CPU’s RIO head adapter (140CRP93200) is installed.
Q: How many 140CRA31200C drop adapters can be connected per RIO trunk?
A: The Quantum RIO architecture supports up to 31 remote drops per RIO head adapter, depending on cable length and repeater configuration.
Q: Can this module be used in a SIL-rated safety application?
A: The standard 140CRA31200C is not SIL-certified. For safety-rated applications, consult Schneider Electric’s Quantum Safety PLC product line (140CPU671 60S series).
Q: What is the maximum RIO cable distance without a repeater?
A: Up to 1,500 m (approximately 4,900 ft) without a repeater. With Quantum RIO repeaters (140CRP93100), total bus length can extend to 3,000 m.
Q: Do you supply the coaxial cable and T-connectors?
A: We can source Schneider Electric-compatible RIO cable accessories. Contact us with your cable length and drop count requirements for a bundled quote.
