Schneider Electric 140DAI55300 Digital Input Module

Schneider Electric 140DAI55300 Modicon Quantum discrete input module provides 32 digital input channels rated for 115 V AC, designed for use with Modicon Quantum PLCs. This 32‑point AC input module accepts field signals from devices such as limit switches, pushbuttons, proximity sensors, and safety interlocks, converting each into a logic state readable by the Quantum controller. As part of the Modicon Quantum I/O family, it integrates with a Quantum rack and backplane for straightforward wiring and scalable I/O expansion in industrial automation projects. The 140DAI55300 is configured for 115 V AC operation, aligning with common North American power systems and typical line frequencies found in factory environments, enabling reliable digital input monitoring on manufacturing lines, packaging equipment, and process-control applications. These inputs support dense, modular automation layouts, allowing engineers to design compact control interfaces that centralize sensing and state reporting while preserving compatibility with Schneider Electric’s configuration tools and Quantum ecosystem engineering workflows.
