Schneider Electric 140-DAI-543-00 Input Module

Schneider Electric 140DAI54300 is a Modicon Quantum discrete input module that provides 16 inputs for AC logic signals, configured for 100–120 V AC (nominally 115 V). The module is designed to mount in a Modicon Quantum I/O rack and presents two input channels for field devices such as pushbuttons and limit switches. It is part of the Modicon Quantum I/O family and is listed as discontinued in several regions, with regional end-of-commercialization notices. Schneider Electric designates BMXDAI1604 as the recommended replacement for this 16-input, 115 VAC model, aligning with the X80 series. Typical applications include industrial automation tasks requiring direct interfacing of 115 V AC discrete inputs to a Quantum controller, including process lines, material handling, and machine safety interlocks.
