Schneider Electric 140DAI55300 PLC Module

Schneider Electric 140DAI55300 is a Modicon Quantum discrete input module that provides 32 115 V AC inputs, arranged as four 8-channel groups. It connects to the Quantum I/O bus and requires two input words for addressing, with a bus current requirement of 250 mA. Each input channel accepts 115 VAC signals and draws up to 11.1 mA at 57–63 Hz (or up to 13.2 mA at 47–53 Hz), with a line frequency range of 47–63 Hz. As of June 25, 2024, Schneider Electric lists 140DAI55300 as discontinued, with standard service ending June 25, 2026; the recommended migration path is BMXDAI1604, a 16-input discrete input module in the Modicon M580/X80 range.
