Introduction to UniOP eTOP310U101
The UniOP eTOP310U101 is a compact and rugged industrial Human-Machine Interface (HMI), recognized as the “visual interaction bridge” for small to medium-sized automated control systems. As a key product in UniOP’s eTOP series, it integrates a high-brightness touchscreen display, multi-protocol communication capabilities, and simplified programming functions, specializing in enabling operators to monitor real-time process parameters, input control commands, and view fault alerts intuitively. This HMI is widely applied in industries such as manufacturing automation, food & beverage processing, and building energy management—for example, serving as the operation terminal for PLC-controlled conveyor lines, displaying temperature and pressure data of pasteurization equipment, or managing the running status of air conditioning and ventilation systems in industrial workshops. Its industrial-grade design features a scratch-resistant tempered glass panel and IP65 front protection rating, effectively resisting dust, water splashes, and accidental impacts on the production site.
