PRODUCT DETAILS
2711P-T9W21D8S — 9-Inch Widescreen Touch HMI Terminal, 24V DC
The 2711P-T9W21D8S is a 9-inch widescreen touch-only HMI terminal running on 18–30V DC power, with an 800 x 480 WVGA resistive touchscreen display, a single Ethernet port, dual USB ports, and a microSD card slot for application backup and restoration. It supports screen rotation for either horizontal or vertical panel mounting, a flexibility that earlier-generation terminal hardware in the same physical size didn't offer.

Widescreen Format at 9 Inches
The wide 5:3 aspect ratio at this size gives application designers a different layout option than the more square-proportioned 7-inch or standard 10-inch terminals — well suited to status displays with several side-by-side data panels, or applications where a horizontal alarm banner and a wide trend chart benefit from extra width rather than extra height. Screen rotation support means the same physical hardware fits both portrait and landscape panel orientations, useful in machine designs where the available mounting space dictates orientation rather than the application's screen layout preference.
The single Ethernet port covers standard star or linear network topologies for connecting to one controller — installations needing dual-port DLR ring capability would specify the corresponding dual-Ethernet variant in the same terminal family instead.
FAQ
Q: Can this terminal be mounted vertically as well as horizontally?
Yes. The terminal supports screen rotation, allowing the same physical unit to be installed in either orientation depending on the panel layout.
Q: Does the single Ethernet port support DLR ring topology?
No. A single Ethernet port supports star or linear topology connections only. DLR ring participation requires the dual-Ethernet-port variant in the same terminal family.
Q: Can the terminal's battery be replaced without specialized tools?
Yes. The real-time clock battery is a standard replaceable coin-cell type, accessible for field replacement when its multi-year service life is reached.
Q: How is the application transferred to or backed up from this terminal?
Via the microSD card slot for quick copy and restore, the USB ports for drive-based transfer, or over the Ethernet connection from the development software on a networked PC.
