Selection Notes

At 12 inches the HMIST6600 is the largest screen in the ST6 line, giving more room for trend graphs, alarm lists, and multi-zone layouts than the 4-inch HMIST6200 or 7-inch HMIST6400. It shares the same 2 COM / 2 Ethernet port set and 1 GB device memory as the HMIST6400, so the choice between the two comes down to screen size and panel space, not connectivity. Power draw rises to 18.4 W with the larger backlight, which factors into 24 V DC supply sizing.
