It provides eight high-precision inputs with 12-bit resolution, supporting both 1...5 V voltage and 4...20 mA current signals. Designed for demanding industrial environments, this module delivers accurate measurements with a linearity error of only ±0.04% and robust isolation.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eNumber of Inputs: 8 (Differential)\u003c\/li\u003e\n\u003cli\u003eAnalog Input Resolution: 12 bits\u003c\/li\u003e\n\u003cli\u003eLinear Measuring Range: 1...5 V and 4...20 mA\u003c\/li\u003e\n\u003cli\u003eMaximum Input Current: 25 mA\u003c\/li\u003e\n\u003cli\u003eMaximum Input Voltage: 50 VDC\u003c\/li\u003e\n\u003cli\u003eInput Impedance: \u0026gt;20 MΩ (voltage), 250 Ω (current)\u003c\/li\u003e\n\u003cli\u003eLinearity Error: ±0.04%\u003c\/li\u003e\n\u003cli\u003eAccuracy Drift: ±0.0025% of full scale\/°C\u003c\/li\u003e\n\u003cli\u003eUpdate Time: 5 ms\u003c\/li\u003e\n\u003cli\u003ePower Consumption: 2 W\u003c\/li\u003e\n\u003cli\u003eIsolation Between Channels: 30 V DC\u003c\/li\u003e\n\u003cli\u003eIsolation Between Channels and Bus: 1000 V DC (3000 V DC for 60 s)\u003c\/li\u003e\n\u003cli\u003eCommon Mode Rejection: \u0026gt; -72 dB at 60 Hz\u003c\/li\u003e\n\u003cli\u003eNet Weight: 0.7 lb (0.3 kg)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIndustry Applications\u003c\/h2\u003e\u003cp\u003eThe \u003cstrong\u003eSchneider 140ACI03000C\u003c\/strong\u003e excels in process control, factory automation, and machine monitoring. Its differential inputs and high common mode rejection make it ideal for noisy environments, ensuring accurate sensor readings. Use it for temperature, pressure, flow, and level measurement in chemical plants, water treatment, and manufacturing lines.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup\u003c\/h2\u003e\u003cp\u003eMount the \u003cstrong\u003e140ACI03000C\u003c\/strong\u003e in a standard Modicon Quantum rack. Connect differential signals to the screw terminals, observing polarity and using shielded twisted-pair cables for best noise immunity. Configure the addressing requirement of 9 input words in your control software. The module automatically detects broken wires on 4...20 mA loops and undervoltage on 1...5 V ranges.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eThis module features conformal coating (Humiseal 1A33) for protection against moisture and contaminants. It operates reliably in temperatures from 32 to 140 °F (0 to 60 °C) and up to 95% relative humidity. With a 5 ms update time and LED indicators for communication and channel status, routine checks are straightforward. Minimal maintenance is required—periodically inspect connections and cleanliness.\u003c\/p\u003e\u003ch2\u003eCompatibility \u0026amp; Integration\u003c\/h2\u003e\u003cp\u003eThe \u003cstrong\u003eSchneider 140ACI03000C\u003c\/strong\u003e integrates seamlessly with Modicon Quantum controllers and I\/O systems. It supports the standard Quantum backplane bus and requires no special adapters.
