Product Details:

Schneider 140ACI04000 is a rack-mounted 16-channel analog input module for Modicon Quantum PLC automation systems. This module gathers analog signals from field transmitters, pressure sensors, temperature transmitters and other measuring instruments, and converts received analog signals into digital data for processing by the Quantum CPU through the backplane bus. It accepts standard 4-20mA and 0-20mA current input signals, and all sixteen channels can be individually configured to match diverse field measurement requirements. The module adopts high-precision analog-to-digital conversion technology to accurately capture real-time process parameters such as flow rate, liquid level, pressure and temperature. Built-in self-diagnostic functions detect open circuits, wiring errors and internal hardware faults, and transmit fault alarm information to the PLC CPU for rapid on-site troubleshooting. Industrial-grade circuit design provides excellent resistance to mechanical vibration and electromagnetic interference, suitable for long-term continuous operation in power plants, petrochemical plants, water treatment and manufacturing sites. Installed in standard Quantum rack slots, this analog input module communicates stably with the backplane, CPU and other I/O modules to form a complete process data acquisition system. Widely used in industrial process automation projects, this analog acquisition hardware is an indispensable component of Modicon Quantum control systems. It helps operators realize real-time monitoring of field equipment status, improves the accuracy of process control, and reduces the risk of unplanned production shutdowns.
