Distributed I/O Solution – Schneider Electric 140CRP93200 | Modicon Quantum RIO Head Module
Where This Product Is Used
The Schneider Electric 140CRP93200 is a Remote I/O (RIO) Head Module designed for the Modicon Quantum PLC platform. It serves as the communication interface between the Quantum CPU rack and remote I/O drops distributed across the plant floor. Engineers deploy this module in applications where field devices — sensors, actuators, drives, and instrumentation — must be connected over long distances without running individual signal cables back to the main control panel.
Typical deployment environments include:
- Oil & Gas Processing Plants — Remote wellhead and separator skid I/O over S908 RIO bus
- Water & Wastewater Treatment — Distributed pump station monitoring across large facilities
- Power Generation & Utilities — Turbine control and switchgear monitoring with long cable runs
- Automotive Manufacturing — Body shop and paint line distributed I/O drops
- Chemical & Pharmaceutical Plants — Hazardous area remote I/O with intrinsically safe barriers
- Mining & Minerals Processing — Conveyor system and crusher control with remote drops
- Food & Beverage Production — CIP/SIP process control with distributed field I/O

Why Engineers Specify This Model
- Proven S908 RIO Architecture — The 140CRP93200 uses Schneider’s battle-tested S908 coaxial RIO bus, a deterministic, high-reliability protocol trusted in critical process industries for decades.
- Long-Distance I/O Extension — Supports cable runs up to 4,572 m, eliminating the need for costly multi-conductor home-run cables from remote field devices.
- High Drop Density — A single RIO cable supports up to 31 remote drops, each housing multiple I/O modules, enabling large-scale distributed architectures from a single head module.
- Seamless Quantum Integration — Plugs directly into the Modicon Quantum backplane alongside CPU, power supply, and other modules — no external gateway or converter required.
- Redundancy-Ready — Compatible with Quantum Hot Standby (HSB) CPU configurations, supporting redundant RIO cable paths for fault-tolerant operation.
- Deterministic Scan Time — Fixed, predictable I/O scan cycle ensures reliable real-time control performance for process-critical applications.

Application-Specific FAQ
Q: Can the 140CRP93200 be used with Modicon Premium or M340 PLCs?
A: No. The 140CRP93200 is exclusively designed for the Modicon Quantum platform and uses the proprietary S908 RIO bus. It is not compatible with Premium (TSX) or M340 architectures.
Q: How many 140CRP93200 modules can be installed in a single Quantum rack?
A: Multiple RIO head modules can be installed in a Quantum rack (subject to backplane slot availability and power budget), each managing an independent RIO cable with up to 31 drops.
Q: Is the 140CRP93200 compatible with Hot Standby (HSB) CPU configurations?
A: Yes. The module supports Quantum Hot Standby architectures. Redundant RIO cable paths can be configured for fault-tolerant operation using dual 140CRP93200 modules.
Q: What is the maximum I/O point count per RIO cable managed by this module?
A: With 31 drops and up to 8 I/O modules per drop, a single RIO cable can support thousands of I/O points depending on the module types installed.
Q: Can I mix discrete and analog I/O modules in the same remote drop?
A: Yes. Modicon Quantum remote drop racks support mixed I/O configurations — discrete, analog, and specialty modules can coexist in the same drop rack.
Q: What cable type is required for the S908 RIO bus?
A: The S908 RIO bus requires 75Ω coaxial cable (Belden 9463 or equivalent). Schneider Electric part number 490NTW00002 is the recommended pre-terminated cable assembly.
