Product Details:
Schneider 140ACI04000C is a rack-mounted conformal coated 16-channel analog input module for Modicon Quantum PLC automation systems. The conformal coating applied on the PCB protects the circuit board from moisture, dust and corrosive gas, making it suitable for demanding industrial environments. This module collects analog current signals from field sensors and transmitters, then converts analog signals into high-precision digital data and transmits data to the Quantum CPU through the rack backplane. It supports multi-range current input including 4-20mA, 0-20mA and 0-25mA, with 16 differential input channels that can be individually configured to measure pressure, flow, liquid level and temperature variables. Equipped with a single-pole low pass filter with 34Hz cutoff frequency, it effectively suppresses high-frequency noise interference and stabilizes measurement results. The module achieves high measurement accuracy up to ±0.125% full scale, and built-in self-diagnostic functions detect channel open circuit, wiring fault and internal hardware anomalies, feeding alarm status back to the PLC CPU for fast on-site maintenance troubleshooting. Industrial hardware design has strong resistance to mechanical vibration and electromagnetic interference, suitable for long-term continuous operation in offshore platforms, chemical plants and power stations. Installed in standard Quantum rack slots, this analog module communicates reliably with backplane and CPU to build stable field signal acquisition systems. Widely used in critical process automation projects, this coated analog input hardware is a key component of Modicon Quantum control systems. It ensures accurate field data collection under harsh environmental conditions, improves process control stability and reduces unexpected equipment shutdown risks.
