Schneider Electric 140CRA21110 Digital IO Module

Schneider Electric 140CRA21110 is a one-channel DIO drop interface module for the Modicon Quantum PLC family, designed as an AC-powered distributed I/O extension with a single digital I/O port that drops into the Quantum MB+ network. The unit operates from 115 to 230 VAC and acts as a digital input/output interface within the Quantum ecosystem, enabling connection between external field devices and the PLC controller through a dedicated channel. As part of Schneider Electric’s Quantum I/O family, the 140CRA21110 supports modular, scalable wiring for applications requiring remote sensing and basic control signaling, and it complements other MB+ head and DIO adapters to form a cohesive distributed I/O topology for industrial automation.
