Real-World Use & Application Scenarios
In demanding industrial environments, reliable power supply modules are foundational to the smooth functioning of automation and control systems. The Schneider Electric 140CPS21400 power supply module is widely used in manufacturing plants, process industries, and machine control environments to provide stable, efficient, and protected power to critical automation components. Applicable in distributed control systems and programmable logic controller (PLC) platforms such as the Modicon Quantum family, this power supply addresses the challenges of managing fluctuating power demands, protecting against overloads, and ensuring continuous operation without interruptions.
Engineers and system integrators rely on the 140CPS21400 to maintain consistent 5.1 V DC output voltage with an 8 A summable output current capacity, supporting multiple devices running simultaneously without performance degradation. Its summable design facilitates scalable power distribution in complex automation architectures, making it a trusted component for safeguarding sensitive electronics in sectors from automotive assembly to energy management.
Product Introduction & Positioning
The Schneider Electric 140CPS21400 is a standardized power supply module designed for the Modicon Quantum automation platform. It operates with a 24 V DC input voltage range of 20 to 30 volts and provides a summable 5.1 V DC output capable of delivering up to 8 A of continuous current to connected devices.
Positioned as a core power management unit, this module integrates seamlessly into Quantum PLC racks and systems, providing robust power that supports high availability control and data acquisition tasks. Thanks to its internal protection against overloads and overvoltage, the 140CPS21400 enhances system reliability and longevity, elements crucial to engineers and operators who demand uninterrupted performance from their control hardware.
Key Technical Features & Functional Benefits
The 140CPS21400 power supply module features a compact, standardized format compatible with Modicon Quantum racks, making it straightforward to install and replace. Its input current of up to 3800 mA accommodates varying load demands while its high inrush current tolerance (25 A at 24 V) prevents failures during power surges or startup transitions.

Internal protections guard against overvoltage and overload scenarios, reducing the risk of damage to connected components. The module also minimizes power dissipation to enhance energy efficiency, calculated as 6 + (1.8 x output current in amperes), which helps maintain lower operating temperatures and offsets cooling demands.
For operational safety, an alarm output contact rated at 6 A and 220 V notifies users immediately of any power supply faults. Additionally, a green LED serves as a reliable local indicator of power status. This combination of features ensures operators are promptly informed and can take corrective action, minimizing costly downtime.
The module complies with stringent safety and electromagnetic compatibility standards including CSA C22.2 No 142, UL 508, and FM Class 1 Division 2 rating, suitable for industrial environments with rigorous regulatory requirements.
