Product Details

The Schneider 140CPS21400 summable dc power supply module is a high-performance power unit designed for Modicon Quantum PLC racks with 24V DC input power. This modicon quantum power module converts 20~30V DC input into stable 5.1V DC backplane power to supply power for CPU, communication and I/O modules installed on the rack backplane. This summable power supply can run standalone or connect multiple identical modules in parallel to expand total power capacity, which is suitable for large racks equipped with many high-power consumption modules. It can deliver up to 8A output current. A green PWR OK LED indicator and one NC fault alarm relay contact are arranged on the front panel. The relay outputs fault alarm signals when power failure occurs, and the LED helps on-site engineers quickly monitor module operating status and diagnose faults. Built-in overvoltage, overload and short-circuit protection circuits automatically cut off output under abnormal electrical conditions to protect expensive Quantum PLC modules. It supports direct plug-in installation on Quantum backplane and hot swap under specified operating conditions for convenient maintenance. This original product was discontinued on September 15,2023, 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 stable backplane power supply for Modicon Quantum PLC systems powered by DC sources.
