Product Details

The Schneider 140CPS52400 redundant dc power supply module is a high-reliability power unit designed for Modicon Quantum PLC racks with 125V DC power input. This modicon quantum power module accepts 100~150V DC input and converts it into stable 5.1V DC backplane power for CPU, communication and I/O modules installed on the rack backplane. This power module supports parallel load-sharing redundant operation. When two identical 140CPS52400 modules work together, they share the rack load evenly. If one power supply fails, the remaining module will automatically take over the full load without interrupting PLC operation, ensuring continuous production process. It can deliver up to 8A output current under redundant configuration. A green PWR OK LED indicator on the front panel shows real-time module working state, allowing technicians to quickly check power health and perform on-site fault diagnosis. Built-in overvoltage, overload and short-circuit protection circuits can cut off output automatically under abnormal electrical conditions to protect expensive Quantum PLC modules. It supports direct plug-in installation on Quantum backplane and hot swap for convenient maintenance. This original Schneider module was discontinued on Aug 8,2025, widely stocked as spare parts for maintenance and renovation of legacy industrial automation systems. It is widely used in power, petrochemical, metallurgy, water treatment and railway projects to provide redundant stable backplane power supply for Modicon Quantum PLC control racks with 125V DC power source.
