3.5" Compact Industrial HMI Touch Panel – RS232, RS485, USB, Ethernet
Cost-effective 3.5" HMI touch panel with RS232/RS485, USB 2.0, and Ethernet support. Features a resistive touch display, built-in data storage, recipe handling, multilingual interface, and compatibility with multiple PLC protocols.
The 3.5" industrial HMI touch panel is a compact and powerful operator interface designed for small-scale automation and embedded control applications. Despite its small size, it integrates RS232, RS485, USB 2.0, and optional Ethernet, making it ideal for connecting to PLCs, drives, sensors, and meters.
Its 320×240 TFT display with 65K colors provides clear graphics, while the high-reliability resistive touch panel ensures accurate and durable operation. The device runs on a dual-core 1GHz CPU with 128MB RAM/ROM, delivering fast performance for real-time monitoring and control.
This HMI also supports recipe storage, historical data, alarms, and trend curves, with data saved directly to USB or optional SD card. With built-in multilingual support, vector libraries, and GIF/static image compatibility, it enables user-friendly and flexible interface design.
Compared to larger-brand HMIs, this model delivers equivalent performance and industrial reliability at a fraction of the cost, making it an excellent choice for OEMs, system integrators, and cost-sensitive industrial projects.
