Product Introduction
The Schneider Electric 140CRA93200C is a RIO Drop Adaptor Module used within the Modicon Quantum automation platform, specifically for Remote I/O (RIO) architecture. This module is a critical part of Quantum’s distributed control system, enabling the connection of remote I/O drops to a Quantum controller via the RIO network. It serves as a bridge between the RIO head and the distributed I/O modules, supporting high-performance, deterministic communication in real-time control applications.
Designed for use in large-scale industrial automation environments, the 140CRA93200C supports the extended flexibility, scalability, and reliability that Modicon systems are known for. It simplifies system expansion, reduces wiring complexity, and enhances data exchange efficiency across distributed nodes. Its robust design ensures reliable operation even in harsh environments.

Frequently Asked Questions (FAQ)
1. What does the 140CRA93200C module do in a Quantum system?
It acts as a remote I/O drop adaptor, connecting a segment of remote I/O modules to the main Quantum controller over the RIO bus.
2. Can I use this module in a non-Schneider system?
No, it is designed specifically for Schneider’s Modicon Quantum architecture and is not interoperable with third-party PLCs.
3. What communication medium does the RIO drop use?
It uses coaxial cable to connect remote I/O drops to the RIO head module, supporting long-distance runs up to 3 km.
4. Does this module support hot-swapping?
Yes, the 140CRA93200C can be inserted or removed while the rack is powered, minimizing system downtime.
5. How many remote drops can be connected to a single RIO head?
A typical RIO network can support up to 31 drops, depending on the configuration and controller capacity.
6. What diagnostic features are available on the module?
It includes LED indicators for power, communication status, and fault detection for easy maintenance.
7. Is any programming required for this module?
No programming is required on the module itself, but configuration through Schneider’s Unity Pro or EcoStruxure Control Expert is needed.
8. What type of connector is used for the RIO coaxial bus?
It uses BNC connectors compatible with RG-11 or similar industrial coaxial cable types.
9. Can this module be used in ATEX-rated environments?
Yes, the 140CRA93200C is certified for use in ATEX Zone 2 hazardous environments.
