Schneider 140CPU65260C Quantum Unity Processor PLC Module

Product Description

The 140CPU65260C Unity Processor is a high-performance CPU module developed for the Schneider Electric Modicon Quantum platform. This version features a conformal coating (Humiseal 1A33), specifically designed to protect electronic components from moisture, dust, and corrosive atmospheres, making it suitable for harsh industrial environments such as offshore, chemical plants, and heavy industry.

With a 266 MHz processor and enhanced 3072 kB internal RAM, this unit provides reliable execution of complex control strategies, large-scale distributed I/O management, and deterministic task handling. It integrates multiple communication interfaces and supports a wide range of industrial protocols, enabling seamless system integration across legacy and modern architectures.
