Schneider 140CRA93100C | Quantum RIO Drop Adaptor Module

The 140CRA93100C connects remote I/O drops to a Quantum PLC controller. This adaptor module manages data exchange over the remote I/O network. It allows you to place I/O racks up to 1200 meters away. Consequently, you can monitor and control distributed machinery from a central location.

You can install this adaptor in any Quantum RIO drop rack. The 140CRA93100C communicates with the main CPU via fiber optic or coaxial cable. It automatically handles all network timing and error checking tasks. Therefore, your processor focuses on logic while this module manages communications.

Network Specifications and Communication Details

The module uses either coaxial or fiber optic physical media. The 140CRA93100C achieves transmission rates up to 1.5 Mbit/second. It supports RIO drops with up to 64 words of input and output data. Dual communication ports allow daisy-chaining multiple drops on one network.

Six LED indicators show module and network status clearly. The 140CRA93100C includes built-in diagnostic counters for network analysis. A rotary switch sets the drop address from 0 to 31. Below is a complete breakdown of its technical characteristics.

Interface Layout and Connection Options

Two 9-pin D-sub female connectors serve as the network interface. The 140CRA93100C labels these ports as IN and OUT for proper orientation. A third 9-pin connector provides a programming or diagnostic access port. The module fits into any standard Quantum rack slot location.

You must connect the RIO network cable to both ports sequentially. The 140CRA93100C passes signals through from IN to OUT automatically. A terminating resistor must be installed on the last drop’s open port. Therefore, proper network termination ensures reliable communication across all drops.

Operational Benefits for Distributed Systems

This adaptor simplifies adding remote I/O to factory floor machinery. The 140CRA93100C eliminates hundreds of meters of home-run control wiring. It supports hot standby configurations for critical process applications. Engineers trust this module for reliable distributed control in large facilities.
