Product Details

The Schneider 140DAI35300 discrete input module is a digital signal acquisition module for Modicon Quantum PLC automation system, equipped with 32 channels of 24V AC digital input, used to collect on-site switch status signals and transmit them to the Quantum CPU for logic processing. The module is divided into 4 groups of 8 channels, occupying 2 input words in PLC address space. Each channel input current ranges from 11.1 to 13.2mA and maximum leakage current is 1.9mA. It consumes 250mA bus current with maximum power dissipation of 10.9W. Built-in channel fault detection circuit can identify abnormal input status and send diagnostic information to the Quantum CPU. Multiple LED indicators display channel on-off status and module fault alarm, helping maintenance staff quickly check field signal state. It can be directly inserted into the Quantum backplane rack and supports hot swap for convenient module replacement during system maintenance. This original Schneider product was discontinued on Mar 15,2025 and end-of-service on Dec 31,2030, widely stocked as spare replacement parts for maintenance and upgrade of legacy industrial automation systems. It is widely deployed in power, petrochemical, water treatment and manufacturing plants as 24V AC digital input acquisition module for Modicon Quantum automation racks.
