Schneider Electric M340 Programmable Automation Controller

Schneider Electric's M340 Programmable Automation Controller is a mid-range Modicon PAC that provides scalable, real-time control for industrial machines, processes, and infrastructure. It uses the modular X80 I/O architecture for expansion and supports Ethernet, Modbus, and CANopen communications (processor dependent), with rack-mount installation and compatibility with EcoStruxure Control Expert (Unity Pro). SD Card memory supports application backups and firmware updates (processor dependent), making it suitable for both new installations and modernization or migration from legacy PLCs. Commonly deployed in factory automation, water and wastewater facilities, material handling, energy applications, packaging machinery, mining, and food and beverage production, where dependable real-time control and seamless network integration are essential.
