140CRA93200 Schneider 140CRA93200 Remote I/O Adapter Modules

Product Description

The 140CRA93200 is a Remote I/O (RIO) drop adapter for the Modicon Quantum automation platform. It enables distributed I/O expansion by connecting a remote Quantum rack to a central PLC processor over a coaxial S908 Remote I/O network. Designed for deterministic, high-reliability communication, the module ensures synchronized I/O updates across geographically distributed industrial systems.

Core Function

The 140CRA93200 interfaces the remote Quantum backplane with an S908 RIO head module, managing time-critical data exchange with minimal latency. It maintains deterministic I/O behavior required for high-availability and continuous-process applications.

Technical Specifications

Installation & Maintenance

The 140CRA93200 supports hot swap in most Quantum configurations, allowing replacement without powering down the entire system (application permitting temporary RIO drop loss). The front-panel protective door safeguards internal components while allowing clear field labeling.

Application

Commonly used in distributed automation architectures, including:

• Large process plants

• Power generation and substations

• Water and wastewater treatment

• Material handling systems with remote I/O islands

FAQ

Does this module support Modbus Plus communication?
Yes. The module includes an integrated Modbus Plus (RS-485) port for programming terminals or HMI connections at the remote drop.

Can the 140CRA93200 be used as a standalone PLC interface?
No. This is a RIO drop module and must be paired with a RIO head module (e.g., 140CRP93100 or 140CRP93200) located at the CPU rack.
