Schneider Electric 140CPU11303 Programmable Logic Controller Module

The Schneider Electric 140CPU11303 is a Modicon Quantum Concept Processor CPU module that acts as the brain of a Quantum PLC system, designed to drop into a standard Quantum backplane and orchestrate the execution of control logic, memory management, and coordination between the processor, I/O modules, and field networks. It provides 512 KB of RAM for runtime and program storage, 16 KB of dedicated User Logic space, and 10 KB of registers to hold numeric values, timers, and status flags, while offering one Modbus port and one Modbus Plus port for field communication and networked device integration. Operating within the Modicon Quantum ecosystem, the 140CPU11303 is intended for industrial automation tasks that require deterministic performance and scalable architectures, and it draws about 790 mA during operation, enabling reliable interaction with Quantum I/O modules and support for expansion or hot‑standby configurations as part of a broader control system.
