Product Introduction
When a power supply failure threatens to halt critical industrial processes, the Schneider 140CPS22400C provides reliable redundancy to keep your Modicon Quantum system operational. This redundant power supply module accepts an input voltage range of 20 to 30 VDC and delivers a stable output of 5.1 VDC at up to 8 A, ensuring continuous power even if one supply unit fails. Its alarm output and internal overvoltage protection add layers of safety, making it ideal for mission-critical automation environments.
Technical Specifications Breakdown
The Schneider 140CPS22400C offers several key parameters that define its performance:
-
Input Voltage: 20 to 30 VDC – accommodates a wide range of DC bus voltages found in industrial settings.
-
Output Current: 8 A (redundant) – guarantees sufficient power for multiple modules while maintaining fault tolerance.
-
Inrush Current: 25 A at 24 VDC, 14 A at 20 VDC – important for sizing upstream protection and power supplies.
-
Overload Protection: Withstands 2.3 times the maximum rated input voltage for 1.3 ms – prevents damage during transient surges.
-
Alarm Output: 1 Normally Closed contact rated at 6 A, 220 V – provides remote notification of power supply faults.
These specs ensure that the module operates robustly even under adverse conditions, reducing the risk of unexpected downtime.
Industry Applications
The Schneider 140CPS22400C is commonly used in manufacturing plants, water treatment facilities, and energy management systems where continuous operation is critical. For example, in a continuous chemical processing plant, the redundancy feature ensures that even if one power supply fails, the control system stays online, preventing costly production halts. Similarly, in a power distribution substation, the alarm output triggers an immediate alert to maintenance personnel, enabling rapid response.
Maintenance & Reliability
Routine inspection of the Schneider 140CPS22400C should include checking the local LED indicators for normal status and verifying that the alarm contact is properly wired. Because the module includes overvoltage and overload protection, it withstands common power anomalies without frequent servicing. By investing in this redundant design, facility managers reduce mean time to repair (MTTR) and extend the overall life of the control system – a clear cost benefit over non-redundant alternatives.
Compatibility & Integration
The 140CPS22400C is designed specifically for the Schneider Electric Modicon Quantum series chassis. It is compatible with all Quantum backplanes and accepts standard 20–30 VDC plant power. Integration is straightforward: simply insert the module into the appropriate slot, connect the DC input, and wire the alarm output to your monitoring system. No additional software configuration is required.
Selection Guide & Purchasing Advice
Before purchasing the Schneider 140CPS22400C, verify that your chassis supports redundant power supply modules and that your system voltage is within the 20–30 VDC range. Ensure your upstream circuit breaker can handle the inrush current of 25 A at 24 VDC. For reliable sourcing, UBEST Automation (ubest101) offers genuine surplus and new modules with prompt shipping.
