Schneider Electric 140CPU43412U Quantum Unity Processor

Schneider Electric's 140CPU43412U Unity Processor is a Unity-era CPU module for the Modicon Quantum automation platform, delivering 1056 KB of internal RAM and a 66 MHz clock to handle control logic and data processing within a Quantum rack. This module supports Modbus communications with two RS-232 ports and one Modbus Plus interface, enabling reliable fieldbus connectivity for industrial equipment. Schneider Electric lists this model as a legacy Unity CPU, with end-of-sale and end-of-service dates set for December 31, 2026, and it is recommended to migrate to the M580 family for future projects. Designed for Unity-based applications within the Quantum ecosystem, it provides a compact, network-capable controller for deterministic control and data exchange in automation networks.
