140ACI03000C

The 140ACI03000C module by Schneider Electric is an analog input device from the Modicon series, facilitating the connection of up to eight differential inputs. This technical component is characterized by a 12-bit analog input resolution, enabling precise measurements within linear ranges of 1...5 V and 4...20 mA. Users must account for an addressing requirement of 9 input words when integrating this module into their systems.

The module can accommodate a maximum input voltage of 50 VDC and supports an input current up to 25 mA, making it versatile for various applications. Its input impedance boasts values exceeding 20 MΩ for voltage signals while yielding 250 Ω for current inputs, ensuring minimal loading on the sensor. With a linearity error of ±0.04%, the module demonstrates a high degree of accuracy, with drift specifications of ±0.0025% of the full scale per degree Celsius.

Designed with channel isolation in mind, this unit provides a significant 30 V DC isolation between its channels, paired with a robust 1000 V DC isolation between the channels and the communication bus (3000 V DC for up to 60 seconds). The update time stands at 5 milliseconds, enabling quick responsiveness. This module also exhibits impressive common mode rejection capabilities, measuring better than -72 dB at 60 Hz, which helps mitigate noise interference. Additionally, its power consumption is rated at 2 W, contributing to overall operational efficiency.
