DOP-103BQ 4.3-Inch Basic HMI Touchscreen 480x272 Serial | Delta

The Original New Delta DOP-103BQ is a 4.3-inch Basic Human Machine Interface (HMI) from the DOP-100 Series, designed for simple installation and reliable operation in industrial environments. Featuring a 480×272 TFT LCD display with 65,536 colors and a 4-wire resistive touchscreen, it provides clear visualization and intuitive operator control for packaging, textile, woodworking, and rubber/plastic machinery. Powered by an ARM Cortex-A8 800 MHz processor with 256 MB RAM and 256 MB Flash ROM, the panel delivers responsive performance for basic HMI applications. The IP65 / NEMA 4 rated front panel ensures protection against dust and water ingress, while the built-in RTC, USB Host/Client ports, and serial communication ports enable flexible system integration. Programmed with Delta's DOPSoft software.
