Remote I/O Automation Solution – Schneider Electric 140CRA93100 | Quantum Series
Where This Product Is Used
The Schneider Electric 140CRA93100 is a Quantum Remote I/O (RIO) Adaptor Module designed for distributed control architectures in demanding industrial environments. Engineers specify this module when they need to extend Modicon Quantum PLC I/O capacity across long distances without running individual signal cables back to the main rack.
Typical deployment sites include:
- Oil & Gas Facilities – Remote wellhead monitoring, pipeline SCADA, and compressor station control where field devices are spread across large areas.
- Water & Wastewater Treatment Plants – Pump station automation, valve control, and flow monitoring across distributed lift stations.
- Power Generation & Utilities – Substation automation, turbine control auxiliaries, and distributed protection relay interfacing.
- Automotive Manufacturing – Body-in-white welding lines, paint shop conveyors, and assembly transfer systems requiring high-density I/O at multiple stations.
- Food & Beverage Processing – CIP (Clean-In-Place) systems, filling lines, and cold-storage monitoring with remote drop I/O.
- Mining & Minerals – Conveyor belt control, crusher automation, and remote pump control in harsh, dusty environments.
- Chemical & Petrochemical Plants – Distributed safety instrumented systems (SIS) and process control loops requiring IEC 61511-compliant architectures.

Why Engineers Specify This Model
- Proven Modbus Plus Architecture – The 140CRA93100 uses Schneider’s battle-tested Modbus Plus protocol, delivering deterministic, high-speed communication between the Quantum CPU and remote I/O drops with minimal latency.
- Scalable Distributed I/O – Supports up to 31 RIO drops per MB+ segment, enabling engineers to scale field I/O without redesigning the control network topology.
- Backward Compatibility – Fully compatible with the entire Quantum I/O module library (140xxx series), protecting existing investments in field wiring and I/O hardware.
- Rugged Industrial Design – Rated for wide temperature ranges and high-humidity environments, making it suitable for outdoor enclosures and harsh process areas.
- Simplified Commissioning – Drop address is set via rotary switches on the module face, eliminating software configuration for network addressing.
- Long-Term Availability – Konmask.com maintains verified stock of legacy Quantum modules to support brownfield plant maintenance and MRO procurement.

Application-Specific FAQ
Q: Can the 140CRA93100 be used with a Quantum Hot Standby (HSBY) CPU system?
A: Yes. The 140CRA93100 is fully compatible with Quantum Hot Standby configurations. Both primary and standby CPUs communicate with the RIO drops via the Modbus Plus network, and the adaptor module handles the switchover transparently.
Q: What is the maximum cable distance for a Modbus Plus RIO segment?
A: A single Modbus Plus segment supports up to 450 meters (1,476 ft) of cable. With repeaters (490NRP95400), the network can be extended to cover larger plant footprints.
Q: How do I set the drop address on the 140CRA93100?
A: The drop address is configured using the two rotary switches on the module’s front face. Drop addresses range from 01 to 31. The address must be unique on the Modbus Plus segment and set before powering up the drop.
Q: Is the 140CRA93100 compatible with Unity Pro / EcoStruxure Control Expert?
A: Yes. Quantum RIO drops using the 140CRA93100 are fully supported in EcoStruxure Control Expert (formerly Unity Pro). The I/O modules in the drop are configured in the I/O bus editor under the Quantum CPU project.
Q: Can I mix analog and discrete I/O modules in the same RIO drop?
A: Yes. The 140CRA93100 supports any combination of Quantum 140xxx series I/O modules in the same backplane, up to the power supply capacity of the drop.
Q: Do you provide a warranty on this module?
A: Konmask.com provides a 90-day functional warranty on all modules. Extended warranty and exchange programs are available — contact us for details.
