Schneider 140ACI04000

Product Overview

The Schneider Electric 140ACI04000 is a 16-channel differential analog input module designed for use within the Modicon Quantum automation platform. It is capable of receiving standard process current signals (0–20 mA, 4–20 mA, and 0–25 mA) from field instrumentation such as pressure transmitters, flow meters, and temperature sensors.

Its robust design, high accuracy, and diagnostic features make it ideal for demanding applications in process control, energy monitoring, and water treatment systems. The module supports hot swapping and is compatible with all Quantum CPU bases.
