Schneider 140NOM25200 DIO Headend Adapter
Product Overview
The Schneider 140NOM25200 is a Distributed I/O (DIO) headend adapter module engineered for use with the Modicon Quantum automation platform. It serves as a communication interface between the Quantum PLC and remote I/O islands using the Remote I/O (RIO) or DIO architecture. Designed for high-speed and deterministic data exchange, this module plays a crucial role in enabling the decentralized control of field devices across complex industrial systems, including manufacturing lines, utilities, and process plants.
