4.3″ HMI Touchscreen | 480×272 Display | ARM9 TTL Communication
4.3-inch capacitive touchscreen HMI with 480×272 resolution, ARM9 600MHz CPU, dual TTL communication, SD card download, IP65 front panel, and power failure data retention.
Product Summary
The AMT043W024-L480X272C-0TT is a 4.3-inch TFT LCD display designed for industrial applications that require a compact yet robust visual interface. It features a resolution of 480×272 pixels and supports 65,536 colors, providing clear and detailed visuals. The screen brightness is set at 250 cd/m², and the LED backlight has a lifespan of 20,000 hours with adjustable brightness settings.
This model utilizes a capacitive touchscreen, offering superior touch sensitivity and durability. Powered by a 600MHz ARM9 CPU with 32MB DDR2 memory, it includes 16MB of SPI NOR Flash for storage. Notably, this version does not support a real-time clock (RTC) but does have a built-in buzzer and supports data retention during power loss.
Program downloads are performed via an SD card, as there are no USB ports available. It features two TTL serial communication ports, which differ from the RS232/RS485 options available on other models. The device operates at a voltage of DC 5V and includes power protection with +/-1KV lightning surge protection. It meets CE & ROHS standards, ensuring compliance with international safety and electromagnetic compatibility requirements. The operating temperature range is from -10°C to 50°C, and it can be stored in temperatures ranging from -30°C to 70°C.
