Product Overview

The 140ACI03000 (Model: 140ACI03000) is a high-performance analog input module engineered for the Schneider Electric Modicon Quantum PLC platform. It provides 8 differential channels designed for high-precision data acquisition in complex process control environments. This module is specifically optimized for standard industrial signals, including 4–20 mA current loops and 1–5 VDC voltage inputs, ensuring seamless integration with field transmitters.

To maintain signal integrity in electrically noisy industrial settings, the 140ACI03000 (Part Number: 140ACI03000) features an integrated single-pole low-pass filter with a –3 dB cutoff frequency at 15 Hz. This hardware-based filtering effectively suppresses high-frequency interference, providing stable and repeatable process data for critical control loops in chemical processing, power generation, and water treatment.
