Schneider Electric 140ACI04000 Analog Input Module

Schneider Electric 140ACI04000 is a Modicon Quantum 16‑channel analog input module with differential, multi‑range current inputs (4–20 mA, 0–20 mA, 0–25 mA). Each channel provides resolutions of 0…16000 counts for 4–20 mA, 0…20000 counts for 0–20 mA, or 0…25000 counts for 0–25 mA, with an absolute maximum input of 30 mA and an input impedance of 250 Ω. The module offers a 15 ms update time (2 wires/4 wires), 1780 V AC isolation between channels and the bus, and a bus current requirement of 360 mA, with about 5 W power dissipation and a net weight of 0.3 kg; it uses 17 input words for addressing and provides LEDs for bus activity, external fault, and per‑channel status. The unit is CE marked, and Schneider Electric lists a discontinuation date of December 31, 2022.
