Product Details:

Schneider 140ACI03000C is a rack-mounted 8-channel multi-range analog input module with conformal coating for Modicon Quantum PLC automation systems. This coated version is specially designed for harsh industrial environments with high humidity, corrosive gas and dust. It collects analog signals from field transmitters and sensors, then converts analog signals into 12-bit digital data and transmits the processed data to the Quantum CPU via the rack backplane. It supports 4-20mA current signal and 1-5V voltage signal input, each of the eight independent differential channels can be configured separately to measure pressure, flow, liquid level and temperature variables. The built-in single-pole low pass filter with 15Hz cutoff frequency suppresses high-frequency signal noise and improves measurement stability. The conformal coating protects the PCB circuit from condensation, chemical dust and corrosion, extending service life under severe working conditions. Built-in module self-diagnosis functions detect channel open circuit, wiring fault and internal hardware anomalies, feeding fault status back to the PLC CPU for fast maintenance troubleshooting. Industrial hardware design has strong resistance to vibration and electromagnetic interference. Installed in standard Quantum rack slots, this analog module communicates reliably with backplane and CPU to build a stable field data acquisition system. Widely used in offshore, chemical, power and heavy process industries, this coated analog input module is a critical component of Modicon Quantum control systems. It ensures stable and accurate field signal collection in tough environments, reduces unexpected equipment failure risks and supports continuous safe production operation.
