140ACI03000 Schneider Modicon Quantum Analog Input Module

Product Description

The 140ACI03000 is a high-precision analog input module for the Modicon Quantum PLC platform, designed for accurate industrial signal acquisition. It supports 8 differential input channels for 1–5 V and 4–20 mA signals, delivering stable and repeatable measurements. An integrated single-pole low-pass filter (−3 dB @ 15 Hz) suppresses high-frequency noise, ensuring reliable process data in electrically noisy environments.

Technical Specifications

Advanced Diagnostics

The 140ACI03000 incorporates proactive fault detection to improve system reliability:

• Broken wire detection for 4–20 mA loops when current falls below threshold

• Undervoltage monitoring for 1–5 V inputs indicating signal degradation

These diagnostics reduce troubleshooting time and help prevent unplanned downtime.

Application

Commonly used in process control and monitoring systems, including:

• Pressure, flow, and level measurement

• Chemical and batch processing

• Power generation auxiliaries

• Water and wastewater treatment

FAQ

Does this module provide loop power for 4–20 mA signals?
No. External loop power or a field power supply is required to drive current through the internal 250 Ω precision resistors.

Can voltage and current inputs be mixed on the same module?
Yes, but each channel (or channel group) must be correctly wired and configured in software to match the assigned signal type.

Which terminal block is recommended?
The standard Modicon Quantum 40-pin terminal block (140XTS00200).
