Schneider Electric 140SDI95300S Safety Digital Input Module

Schneider Electric 140SDI95300S is a safety digital input module for the Modicon Quantum automation platform. This 16-channel, 24 V DC discrete input module is designed to monitor safety sensor signals—such as emergency stops, safety interlocks, and similar safety-related inputs—within a Quantum safety I/O network. The module provides safety diagnostics by monitoring the sensor power supply on the process side and reporting channel states to the safety controller, enabling fault detection and status verification essential for safety-critical applications. As part of Schneider Electric's Modicon Quantum I/O family, the 140SDI95300S integrates with Quantum backplanes to form a safety-rated digital input array that can support SIL2-level safety configurations, with TÜV Rheinland certification for that safety use. With 16 independent inputs at 24 V DC, it supports scalable expansion of safety sensing coverage in industrial automation while keeping wiring and topology consistent within the Quantum architecture.
