Schneider Electric 140DDI35300 Modicon Quantum Input Module

Product Description

Product Overview

The 140DDI35300 is a low-voltage DC discrete input module designed for Schneider Electric’s Modicon Quantum automation platform. It enables reliable acquisition of 24 VDC digital signals from field devices and transfers them to the Quantum PLC backplane with high accuracy and electrical isolation.

This module is commonly used in large-scale industrial automation and process control systems where stable signal processing, noise immunity, and long-term reliability are critical. Its standard Quantum form factor allows seamless installation in existing I/O racks.
