Overview
The 140CRP93100 is a Schneider Modicon Quantum RIO head-end adaptor module, order code 140-CRP-931-00, that connects a Quantum CPU to remote I/O drops over a 75 Ohm coaxial cable at 1544 Mbit/s. It supports up to 31 drops per network with 64 input and 64 output words per drop, draws 3.0 W, and mounts on a chassis. This module is marked as discontinued.
As the head-end adaptor, the 140CRP93100 sits at the CPU side of a Modicon Quantum remote I/O network, translating the backplane bus to a coaxial drop line. It handles 1544 Mbit/s signalling over 75 Ohm cable and supports up to 31 drops, each carrying 64 input and 64 output words. The module is compatible with Quantum 200/500/800 series and Symax drops in any mix. A single female F connector, elbowed with a single cable, provides the coaxial interface. Power-up diagnostics include memory and LAN controller checks.
Applications
This RIO head-end adaptor is used in Modicon Quantum automation platforms to distribute remote I/O across a plant floor — common in process control, material handling, and large machine cells where I/O must be located near field devices rather than in a single central cabinet.
Compliance & certifications
The module carries CE marking, UL 508 and CSA C22.2 No 142 certification, FM Class 1 Division 2 approval for hazardous locations, and is listed under California Proposition 65.
