Schneider Electric 140ACI04000 Analog Input Module

Schneider Electric 140ACI04000 Analog Input Module is a 16-differential-input, current-input card for Modicon Quantum PLCs, designed to capture analog process signals from field sensors within the Quantum I/O framework. It provides multirange current measurement on every channel (0–20 mA, 4–20 mA, or 0–25 mA), enabling direct connection to common 4–20 mA transmitters and other current-loop sensors, and it supports consistent scaling of readings to engineering units across the entire card. Designed for the Modicon Quantum automation platform, the module mounts in a Quantum I/O rack and converts analog current signals into digital values that the PLC reads through the backplane, integrating with Schneider Electric's broader automation ecosystem. Typical applications include process automation and instrumentation where sensors provide current-loop signals for variables such as flow, pressure, temperature, and level, making it suitable for industries like water treatment, chemical processing, manufacturing, and energy management. The 140ACI04000 is Schneider Electric's 16 I multirange analog input module for Quantum systems, delivering 16 input channels with multi-range current measurement and straightforward integration into existing Quantum hardware and software configurations.
