Schneider Electric 140ACI03000 Analog Input Module

Schneider Electric 140ACI03000 is an 8-channel analog input module for Modicon Quantum systems on the X80 bus, delivering isolated high-level inputs in a unipolar, multi-range configuration with 12-bit resolution. Each of the eight channels accepts current signals in 0 to 20 mA or 4 to 20 mA ranges, or voltage signals up to 10 V, enabling flexible sensor interfacing on a single module. The module is galvanically isolated and carries a maximum channel-to-channel working voltage limit of 30 V DC. Cataloged as 140ACI03000, this analog input module is part of Schneider Electric's Modicon Quantum lineup and is positioned as an 8-channel unipolar input card. It was discontinued by Schneider Electric on January 15, 2023, with standard support continuing through December 31, 2030; Schneider lists BMXAMI0810 as the recommended replacement for the 8-input analog input function on X80, aligning with the X80-compatible BMXAMI family. In practical use within legacy Quantum installations, the 140ACI03000 converts analog sensor signals into digital values for PLC processing, offering 12-bit measurement resolution and isolated inputs to help protect the controller and improve noise immunity.
