Schneider 140ACI03000

Schneider 140ACI03000 Product Overview

The Schneider 140ACI03000 is an analog input module from the Modicon Quantum series of Programmable Logic Controllers (PLCs), which are widely recognized for their high performance, robustness, and modular flexibility. Specifically, this module is designed to provide 8 isolated current input channels for analog signal acquisition in industrial automation systems.

This module accepts standard 4–20 mA analog signals, which are commonly used in process control for transmitting data from sensors and field devices to the control system. Each channel on the 140ACI03000 is individually isolated, enhancing signal integrity and protecting the system from electrical noise, ground loops, and transient voltages.

The 140ACI03000 plays a vital role in industrial settings where accurate and reliable measurement of process variables—such as pressure, flow, temperature, or level—is critical to overall system control and monitoring.

Key Features

1. 8 Isolated Analog Inputs

• Each of the 8 input channels is fully isolated, allowing for independent measurement without interference or signal degradation.

• Channel-to-channel and channel-to-backplane isolation enhances safety and signal clarity in electrically noisy environments.

2. Standard 4–20 mA Input Range

• Supports the industry-standard current input range of 4–20 mA, making it compatible with a wide variety of field sensors and transmitters.

3. High-Resolution Data Acquisition
