The Schneider Electric HMISTM6400 is a 7-inch modular Harmony ST6 touch panel with an 800 x 480 pixel WVGA colour TFT display and 22 mm pushbutton-style panel mounting. It offers 1 COM1 port (RS232C/RS485) and 2 Ethernet ports, runs on 24 V DC, and carries marine approvals (DNV, ABS, RINA, BV) alongside the standard ST6 certifications.
The HMISTM6400 is the modular version of the 7-inch ST6 panel, mounted through a single Ø22 mm pushbutton-style hole instead of a 4-screw panel cut-out, and it adds 2 Ethernet ports rather than the single Ethernet port on some ST6 siblings. It is the only panel in this ST6 selection carrying marine approvals (DNV, ABS, RINA, BV) and a cULus Class I Div 2 hazardous-location rating, so specify it for shipboard HMI or explosive-atmosphere panel builds rather than the standard HMIST6400.
