Features Accurate touch: the touch screen is equipped with an ARM9 processor with high touch accuracy and good interference resistance. COMMUNICATION PROTOCOL AND DATA DOWNLOAD: The communication protocol and screen data can be downloaded to the display without the PLC having to write a communication program. Scope of application: this is a small human-machine interface, which is mainly used for various PLC or intelligent controls with communication port. Fast and stable: the touch screen has low power consumption, fast running speed and stable performance, very practical. Backlight : touch screen with backlight, long LED life up to 20,000 hours, very durable. Specification: Item Type:Industrial Control Touch Screen Display: 7 inch TFT LCD screen.
