Schneider 140ACI04000 Modicon Analog Input Module

Description

The Schneider 140ACI04000 Modicon Analog Input Module is a high-performance component of the Modicon Quantum series, designed for industrial process monitoring and control. Its core function is to receive analog signals such as voltage, current, and signals from temperature, pressure, or flow sensors, then convert them into digital signals recognizable by PLC systems. Key features include 16 analog input channels, enabling simultaneous multi-signal collection to support complex industrial processes. It delivers high measurement accuracy with ±0.125% full scale (FS) precision and ±0.05% FS linearity, paired with 16-bit resolution for precise data capture. The module uses isolated design to suppress common-mode interference, with channel-to-channel and channel-to-power photoelectric isolation for enhanced system stability. It supports multi-range input, including 4-20mA, 0-20mA, 0-10V, and -10V to 10V, adapting to diverse measurement requirements. With DIN rail mounting, it is easy to install and maintain, and it communicates via the Modbus RTU protocol. Operating within a temperature range of -20 degrees Celsius to 70 degrees Celsius, it has an IP20 protection rating, and includes over-current, over-voltage, and short-circuit protection. It is compatible with Modicon Quantum series PLCs and other mainstream controllers, and carries CE and UL certifications for industrial reliability.
