Schneider Electric 140DAI54000 Analog Input Module

Schneider Electric's Modicon Quantum 140DAI54000 is a 16-channel discrete input module for 115 VAC digital signals used in a TSX Quantum I/O rack. It provides 16 individual input points, arranged in two groups of eight, to monitor field devices such as pushbuttons, contact switches, and other 115 VAC sensors, feeding real-time logic status to the Modicon Quantum backplane. Each channel is isolated to help maintain signal integrity in industrial environments and to interface cleanly with the Quantum PLC power and communication scheme. The 140DAI54000 is part of the Modicon Quantum I/O family and is designed to integrate with TSX Quantum hardware for scalable digital input configurations. Schneider Electric lists this module as discontinued as of December 31, 2024, with end-of-service planned for January 30, 2025; for new designs, the recommended path is the X80 family, for example BMXDAI0814, an 8-input module rated for 100–120 VAC, which can be used to achieve similar input configurations in updated installations. This reference highlights Schneider Electric’s approach to modular digital input solutions within the Quantum platform, emphasizing 115 VAC discrete input applications in industrial automation and process control scenarios.
