Application Scenarios
This module is the “heart” of the Modicon Quantum PLC system, typically installed in the leftmost slot (Slot 0) of the rack. It is widely used in power generation, water treatment, oil & gas, and large-scale discrete manufacturing where system uptime is paramount. Its robust design handles harsh electrical environments with voltage fluctuations and high EMI noise.

Technical Principles and Innovative Values
- Innovation Point 1: Summable Redundancy: Unlike basic power supplies, the 140CPS11410 can be paralleled with a second identical unit. If one fails, the other instantly picks up the full load without dropping the PLC rack, enabling true high-availability systems.
- Innovation Point 2: Wide-Range Auto-Sensing Input: It automatically adapts to 115 V or 230 V AC input without manual jumpers. This simplifies global deployment and inventory management, reducing the risk of miswiring damage.
- Innovation Point 3: Industrial Hardening: Built with heavy-duty filtering and conformal-coated PCBs to withstand high inrush currents (up to 38 A) and EMI-rich environments, ensuring clean power delivery to sensitive digital electronics.
Application Cases and Industry Value
In a steel mill’s rolling line, the main control system uses a Modicon Quantum rack with a 140CPS11410 power supply. The drive system generates significant electrical noise. The 140CPS11410’s robust filtering prevents voltage sags and noise from causing PLC faults. Furthermore, the plant configured a redundant power setup; when a lightning strike damaged the primary AC line, the secondary 140CPS11410 maintained uninterrupted power, preventing a multi-million dollar production stoppage and equipment damage.
