Product Details:

Schneider 140CPU11302 is a rack-mounted CPU processor module for Modicon Quantum PLC automation platform. Equipped with a 20MHz 80186 processor and 109kB internal RAM, this unit runs LL984 control logic, collects I/O signals and handles industrial communication tasks. It features one Modbus RS232 port and one Modbus Plus port to exchange data with HMI, SCADA and remote I/O devices. The module supports Concept and ProWORX32 programming software, and integrates a watchdog timer to protect system operation. Built-in self-diagnosis functions detect rack bus, module and I/O faults, helping maintenance staff quickly locate hardware issues. Industrial circuit design offers strong vibration and electromagnetic interference resistance, suitable for long-term continuous operation in power, petrochemical and manufacturing sites. Installed in standard Quantum rack slots, this CPU communicates reliably with backplane and various I/O modules to build complete process control systems. Widely used in industrial process automation, this legacy PLC processor provides stable logic control for production equipment. It enables operators to monitor field data in real time, reduce unexpected shutdown risks and support plant daily operation and maintenance.
