140CPS22400 SCHNEIDER

140CPS22400 SCHNEIDER Power module

Product  Description：

The 140CPS22400 serves as a primary power source for a Modicon Quantum subrack. It converts an external AC voltage source into the internal 5 VDC required by the modules connected to the backplane. This specific model is a Standalone power supply, meaning it is intended to power a rack independently. It features a robust design capable of handling the demanding electrical environments found in heavy industry. The module occupies a single slot on the Quantum backplane and is typically positioned in the leftmost slot to distribute power efficiently across the rack.

Product Parameters

• Input Voltage: 115 VAC to 230 VAC (Nominal)

• Input Voltage Limits: 93 VAC to 276 VAC

• Network Frequency: 47 Hz to 63 Hz

• Output Voltage: 5.1 VDC

• Output Current: 8 A

• Input Current: 1.1 A at 115 VAC or 0.6 A at 230 VAC

• Inrush Current: 38 A at 115 VAC or 19 A at 230 VAC

• Power Interruption Protection: Up to 1 cycle at 47 Hz to 63 Hz

• Power Dissipation: $8.5 \text{ W} + (0.75 \times \text{Output Load in Amps})$

• Isolation Voltage: 1500 V rms AC (input to ground and input to output)

• Status Indicators: LED for "Power OK" (Green)

• Mounting: Occupies 1 slot on the Quantum rack

Product Advantages

One of the main advantages of the 140CPS22400 is its Wide Input Voltage Range, which allows it to operate globally on both 110V and 220V power grids without manual switching. Its 8A Output Capacity provides ample power for a fully loaded rack of complex I/O modules, including high-density analog and communication cards. The module is engineered for Industrial Ruggedness, featuring high isolation ratings and protection against power line transients. Furthermore, its integration with the Modicon Quantum architecture ensures Seamless Mechanical Fit and reliable electrical contact with the backplane bus, reducing the risk of intermittent power failures.

Important Considerations and Precautions

When installing or maintaining the 140CPS22400, several precautions must be strictly followed. Power Cycling should be avoided during critical operations, as the module requires a stable input to maintain the 5V backplane rail. Ensure that the Total Current Consumption of all modules in the rack does not exceed the 8A limit provided by this unit; exceeding this can lead to system instability or thermal shutdown.

Since this is a high-voltage component, always Disconnect Main Power before inserting or removing the module from the rack to prevent electrical arcing or damage to the backplane. Additionally, the module has been marked for End of Life by Schneider Electric (replaced by the Modicon M580 series), so users should consider maintaining a stock of spare parts or planning a migration strategy for long-term system sustainability.

Product Applications

The 140CPS22400 is found in large-scale industrial control systems where reliability is paramount.

• Oil and Gas: Powering control systems for refineries, pipelines, and offshore platforms where stable control logic is required despite fluctuating power conditions.

• Power Generation: Used in turbine control and balance-of-plant systems in fossil fuel or hydroelectric plants.

• Infrastructure and Transportation: Providing logic power for tunnel ventilation systems, water pumping stations, and rail signaling controls.

• Mining and Minerals: Supporting heavy-duty processing equipment and conveyor systems in harsh, dusty environments.

• Chemical Processing: Ensuring continuous operation of reactors and safety systems where power interruptions could lead to hazardous situations.
