Product details

Overview

The 140NOM21100 is a Schneider Modicon Quantum DIO head-end adaptor, order code 140NOM21100, handling 30 input and 32 output words with a power draw of 4.0 W. It mounts on a chassis and carries one Modbus Plus RS485 twisted-pair port and one Modbus RS232 port, both single copper. The module is UL 508 listed and is now discontinued by the manufacturer.

Applications

This adaptor is used in Modicon Quantum-based distributed control systems where I/O racks are located remotely from the main controller — common in process plants, water treatment facilities, and material handling lines. It bridges the backplane to field I/O over Modbus Plus, reducing wiring runs and centralising diagnostics.
