Product Details

The Schneider 140CPS22400 redundant dc power supply module is a high-reliability power unit designed for Modicon Quantum PLC racks with 24V DC power input. This modicon quantum power module accepts 20~30V DC input and converts it into stable 5.1V DC backplane power to supply CPU, communication and I/O modules installed on the rack backplane. It supports parallel load-sharing redundant operation. When two 140CPS22400 power modules work together, they share the rack load evenly. If one unit fails, the remaining power supply will automatically take over 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 and one NC 6A@220V fault relay contact are equipped on the front panel. The relay can send fault alarm signals to the control system, while the LED allows technicians to quickly check power operating status and locate faults on site. Built-in overvoltage, overload and short-circuit protection circuits 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 product was discontinued on Dec 31,2022 and end-of-service on Dec 31,2030, 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 chemical projects to provide redundant stable backplane power supply for Modicon Quantum PLC control racks.
