Product Description

Schneider Electric 140CPU31110 Unity Processor (Modicon Quantum Series)

High-Performance CPU for Large-Scale Industrial Control & Distributed Automation Architectures

1. Product Overview

The Schneider Electric 140CPU31110 is a high-performance Unity processor module from the Modicon Quantum automation platform, serving as the core of large-scale industrial control systems. It integrates a 66 MHz 32-bit RISC processor and 548 kB internal RAM to execute complex logic control, sequence control, and process monitoring tasks with exceptional efficiency and reliability. Featuring versatile communication interfaces and extensive I/O expansion capabilities, it supports seamless integration with local I/O modules, remote I/O stations, distributed I/O networks, HMI devices, and upper-level DCS/SCADA systems, ensuring flexible data exchange in industrial environments. With built-in fault detection, self-diagnostic functions, and compliance with international safety and quality standards (CE, UL, HazLoc), it operates stably in harsh industrial conditions with strong electromagnetic interference (EMI), wide temperature fluctuations (0°C to +60°C), and high vibration levels. It is ideal for manufacturing, oil & gas, power generation, water & wastewater treatment, and infrastructure automation applications where reliable and scalable control is essential for operational efficiency and safety.
