140CRA93100 | Schneider Electric Modicon Quantum RIO Drop Adaptor Module

Product Overview

The Schneider Electric 140CRA93100 serves as the primary Remote I/O (RIO) drop adaptor for the Modicon Quantum automation platform. This module facilitates high-speed communication between a remote I/O rack and the main PLC head-end. By utilizing a rugged coaxial interface, it extends the control architecture across large physical plant areas while maintaining deterministic performance. We provide this module as 100% brand new original equipment, offering a critical solution for maintaining or expanding legacy Quantum systems where manufacturers have discontinued production.

Engineering Advantages

• High-Speed Deterministic Control: The 1544 Mbit/s transmission rate ensures that remote I/O data reaches the processor with minimal latency. This speed allows the Quantum system to manage remote sensors and actuators as effectively as local I/O, supporting time-critical process loops.

• Extensive Rack Expansion: A single 140CRA93100 supports up to 27 I/O expansions per drop. This high capacity allows engineers to centralize remote instrumentation into a single drop, reducing the number of physical nodes required on the coaxial network.

• Rugged Coaxial Signal Integrity: The 35 dB dynamic range compensates for signal attenuation over long cable distances. This feature ensures reliable data packets even in electrically noisy environments where standard twisted-pair cabling might fail.

• Simplified Field Wiring: The module utilizes a standard female F-connector, allowing for secure and quick termination of 75 Ohm coaxial lines. This standardized connection reduces installation time and minimizes the risk of signal reflections caused by poor terminations.

• Superior Electrical Isolation: 500 VDC isolation between the coaxial center and ground protects the backplane electronics from potential ground loops and field-side surges, significantly increasing the lifespan of the remote rack hardware.

FAQs

• Can the 140CRA93100 replace a 140CRA93200 redundant adaptor?

  The 140CRA93100 features a single communication port. While it functions within the same RIO architecture, it does not support cable redundancy. Only use this module in non-redundant RIO drops or where the secondary cable path is not required.

• Is this a genuine Schneider Electric part if it is discontinued?

  Yes. Although the manufacturer has discontinued this series, we supply 100% Brand New original stock. These units remain in their factory-sealed packaging, ensuring they meet the original engineering specifications for your legacy system.

• What is the maximum cable distance supported by this adaptor?

  The distance depends on the quality of the 75 Ohm coaxial cable and the number of taps in the network. The 35 dB dynamic range typically allows for reliable communication over several hundred meters in a standard Modicon RIO topology.

• Does this module require specific software configuration?

  You must configure the RIO drop address via the hardware switches on the module and reflect these settings in your Concept, ProWORX, or Unity Pro software environment to enable successful bus communication.
