Selection Notes

The DT551 variant of the Harmony GTU carries a 10.1-inch WXGA (1280 x 800) display, the highest pixel count in the wide-format GTU screens, so it fits applications needing multiple simultaneous mimic diagrams, trend charts, or dense alarm lists rather than a single-screen layout. Its dual LAN ports let the panel bridge a machine network and a plant network at the same time, and the dual communication interfaces support field devices alongside the network connection. A 30 A inrush current against only 6.5 W steady-state consumption is worth accounting for in upstream fusing on the 12-24 V DC supply, and the 50,000-hour backlight lifespan sets the practical service interval for continuous-duty installations.

Applications

Operator interface for monitoring and communication in demanding automation systems, including industrial control equipment, hazardous locations, and marine applications, where a large multi-object touchscreen with removable storage and dual-network connectivity is needed.
