Schneider Electric 140CPS11100 Programmable Logic Controller Module

Schneider Electric 140CPS11100 is a standalone power supply module for the Modicon Quantum PLC family, designed to provide the necessary AC-powered supply to Quantum racks and modules. It accepts a wide AC input range of 110 to 276 VAC, enabling operation across common global mains voltages. As an official Modicon Quantum power supply, this module was marketed to support early Quantum automation installations before being discontinued by Schneider Electric; the manufacturer notes the 140CPS11100 reference has reached end of commercialization as of May 19, 2026. For users upgrading or migrating, Schneider Electric recommends the BMXCPS3500 power supply module in the Modicon X80 lineup, which supports 100–240 VAC input and is rated at 36 W, aligning with modern replacement standards. The 140CPS11100 carries the Modicon Quantum designation and is identified specifically as a power supply module within that platform, reflecting its role in delivering stable input power to the Quantum backplane and adjacent I/O components when deployed in compatible racks. This model is appropriate for legacy Quantum systems requiring an AC-powered supply module and should be considered for replacement only if maintaining or upgrading an existing Quantum installation.
