Schneider 140CPS11420, that is, a dedicated power supply module for Modicon Quantum PLC system, is installed in the PLC backplane rack to provide stable DC power for CPU, communication modules and various I/O modules. It is widely used in water treatment, metallurgical production lines, automobile manufacturing and other industrial automation sites. It adopts industrial power conversion technology, supporting 115V/230V AC widerange input, and can work in summable or standalone mode according to system configuration.

This module converts alternating current into stable directcurrent output for rackmounted PLC components. It is builtin with overload and overvoltage protection circuits. During system operation, it monitors internal power status in real time. It will trigger fault alarm when abnormal power conditions occur, to avoid damage to other PLC hardware and ensure continuous and reliable power supply for the whole control system.

From the perspective of application objects, this power module applies to water treatment, metallurgy and automobile manufacturing industries. For water treatment industry, it supplies power for PLC control cabinets of sewage treatment equipment. For metallurgical industry, it serves for power supply of productionline PLC systems. For automobile manufacturing industry, it is used for assemblyline automation control racks. It is suitable for industrial equipment maintenance, spare parts replacement and system technical renovation.
