Features High touch precision: The touch screen is equipped with an ARM9 processor, which has high touch precision and good anti-interference. Download communication protocol and data: The communication protocol and screen data can be downloaded to the display without the PLC having to write a communication program. Application This is a small human-machine interface, which is mainly used in various PLC or intelligent controls with communication ports. Fast Running Speed The touch screen has low power consumption, fast running speed and stable performance. Backlit Display Function The touch screen has a backlit display function and the LED life is long, up to 20,000 hours.
