Schneider Electric HMIDT351 Harmony GTU Advanced 7-inch 800x480 WVGA HMI Operator Panel

The Schneider Electric HMIDT351 is a Harmony GTU advanced touchscreen operator panel with a 7-inch color TFT display at 800 x 480 (WVGA) resolution and 262,144 colors. It runs from a 12-24 V DC supply, carries a front-panel IP66/IP67 rating, and adds dual LAN ports with removable storage for machine monitoring in cabinets where forced ventilation is limited or unreliable.

Selection Notes

The DT351 variant of the Harmony GTU carries a 7-inch WVGA screen, which gives enough resolution for mimic diagrams and multi-object screens without the panel footprint a larger touchscreen model needs. Its permanent 60 °C rating and IP66/IP67 front-panel sealing suit enclosures with limited or unreliable forced ventilation rather than open, actively cooled cabinets. The dual LAN ports let the panel sit on a machine network and a plant network at the same time, which single-LAN models in the same range do not support. A 30 A inrush current against only 6.5 W steady-state consumption is worth sizing into the 12-24 V DC supply and any upstream fusing, and the 50,000-hour backlight lifespan sets the practical service interval for panels run continuously.

Applications

Operator interface for industrial control panels, hazardous-location enclosures, and marine equipment where the front panel must withstand washdown (IP66/IP67) and cabinet cooling is limited. The single-touch resistive panel and 262,144-color display support text messages, graphic objects, and mimic diagrams for machine monitoring, with removable storage for data or recipe transfer at the panel.
