Description

Schneider 140CPS11420

Schneider 140CPS11420 is a switching power supply module designed to provide stable and efficient DC power for Quantum PLC racks. It supports both standalone and summable power supply modes, with built-in overload and overvoltage protection as well as status monitoring functions. As the core power guarantee for the stable operation of Quantum automation systems, it is widely used in various industrial automation scenarios.

1. Positioning and System Relationship

System Affiliation

Belongs to the Schneider Electric Modicon Quantum automation platform, model 140CPS11420, classified as a Switching Power Supply Module. It is a standard single-slot power module for the Quantum series, capable of powering a rack independently or working in parallel with other power modules of the same series. It is exclusively compatible with full-size racks of the Quantum series and is not compatible with racks of other Schneider PLC series such as Premium and M340.

Core Role

Positioned as the “power core” of the Quantum system, its core responsibilities include: converting 115VAC/230VAC AC input into a stable 5.1VDC output to power all components in the rack, including CPUs, I/O modules, and adapters; supporting both standalone and summable operating modes to flexibly meet different load requirements; featuring built-in overload and overvoltage protection to monitor power status in real time and cut off output promptly in case of abnormality to avoid damage to system components; and indicating power status via LED indicators for convenient on-site operation and maintenance.

Mounting Position

Mounted on the backplane of a Quantum rack, occupying one standard slot and installed in the dedicated power slot on the left side of the rack. It supplies power to all rack components through the backplane connector. The module is equipped with a green PWR OK LED to clearly indicate operating status and uses a 7-pin terminal connector for standardized wiring and easy maintenance.

System Architecture

Integrated into the Quantum power supply chain: External 115VAC/230VAC AC power → connected to the 140CPS11420 power module → module performs AC-to-DC conversion, filtering and voltage regulation → outputs 5.1VDC power → supplies power to CPU, I/O modules, adapters and other components via the backplane bus. The module monitors output current and voltage in real time; its built-in protection mechanism triggers automatically in case of overload or overvoltage, while the LED provides status feedback to ensure stable system power, forming a complete closed-loop power chain of “input–conversion–supply–protection”.

2. Functions and Technical Features
