Schneider Electric 140DA155300 Modicon IO Module

Schneider Electric's 140DA155300 is a Modicon Quantum discrete input module that provides 32 115 V AC digital inputs in a 4 x 8 configuration. It serves as the input interface for Modicon Quantum I/O, accepting 115 V AC field signals and delivering them to the controller for processing. The module is designed for use with compatible Quantum controllers within a modular, backplane-based I/O network, enabling scalable expansion of digital inputs in industrial automation. Its 32-input footprint supports expanding input capacity without increasing cabinet depth, and it integrates with Schneider Electric's Quantum backplane and I/O bus standards for consistent addressing within existing installations.
