Target Application — DOP-B03E211 Touch Screen Replacement

This listing is for a replacement touch screen / touch panel for the Delta DOP-B03E211 HMI. The touch panel is the front-face input component of the HMI — responsible for detecting user touch input and relaying it to the HMI's control circuitry. A damaged or unresponsive touch panel can render the entire HMI unusable even if the display and PCB are functioning correctly. This replacement touch screen restores full touch input capability, providing a cost-effective alternative to replacing the entire HMI unit.

Important Note: This is a replacement touch screen panel only, not a complete HMI unit. Please verify the article number (MLFB) and physical dimensions match your DOP-B03E211 before ordering. This touch panel is specific to the DOP-B03E211 (Ethernet interface variant); it is not compatible with the DOP-B03S211 (standard variant without Ethernet) or other DOP-B series models.
