HMI (Human-Machine Interface) is a critical category in industrial automation, encompassing devices and software that facilitate interaction between operators and machinery. This category includes touch panels, operator terminals, industrial PCs, and visualization software, designed for seamless control and monitoring of automated systems. Key products may feature high-resolution displays, rugged construction for harsh environments, and intuitive programming interfaces. Advanced HMI solutions often integrate with PLCs and SCADA systems, offering real-time data visualization, alarm management, and multi-language support. Typical applications include factory automation, process control, and equipment supervision, where ergonomic design and reliability are paramount.
