Schneider 140ACI03000 Analog Input Module

Description

Schneider 140ACI03000 Analog Input Module is a compatible industrial automation component, with technical specifications aligned with the closely related Schneider 140ARI03010 Analog Input Module, part of the Modicon Quantum, M340, or Premium series. As an RTD/resistance input module, it is designed to connect RTD or resistance-type sensors such as Pt100, Pt1000, Ni100, and Cu10, supporting 2-wire, 3-wire, or 4-wire sensor configurations. It offers either 4 independently configurable channels or 8 differential input channels, with support for standard resistance ranges from 0 to 4000 ohms, plus temperature probe inputs for process monitoring.

Key performance specifications include a measurement accuracy of ±0.1% full scale (depending on sensor and wiring), 13-bit or 16-bit resolution, and an input impedance of ≥10 MOhm. It features electrical isolation: each channel can withstand 1780 V AC (47-63 Hz) for 60 seconds or 2500 V DC for 60 seconds against the bus, with 300 Vrms AC isolation between channels. A single-pole low-pass filter enhances signal stability.

Built for harsh industrial environments, it operates at 0 to 60 degrees Celsius (or -25 to 55 degrees Celsius) with a storage temperature range of -40 to 85 degrees Celsius, and supports 5% to 95% non-condensing humidity, with an IP20 protection rating. It enables distributed control by extending PLC I/O capabilities, and is ideal for process control applications in petrochemical, power, and metallurgy industries to monitor variables like temperature and pressure.
