Schneider Electric 140-DDI-353-00 Discrete Input Module

The Schneider Electric 140-DDI-353-00 Quantum Discrete Input Module provides 32 digital input channels to interface field devices with Modicon Quantum PLC controllers in industrial automation setups. It runs on a 24 V DC nominal supply (19.2–30 V DC) with positive logic (sink) inputs, arranged in four groups and requiring two input words for addressing, while offering a 2500-ohm input impedance and a ≤1 ms response time. This rack-mounted Quantum module draws 330 mA on the bus and is designed for reliable discrete signal monitoring across manufacturing lines, process automation, packaging, material handling, and water/wastewater facilities. Operating temperature ranges from 0°C to 60°C with storage from −40°C to 85°C, and it serves to expand PLC input capacity or replace failed I/O in Modicon Quantum automation systems.
