Schneider Electric HMIDT351 Harmony GTU 7 in. WVGA Touchscreen

HMIDT351 a Harmony GTU 7 in. advanced touchscreen panel

The HMIDT351 is a Schneider Electric product listed in the datasheet as: advanced touchscreen panel, Harmony GTU, 7inch wide display, 800 x 480pixels WVGA. The HMIDT351 is a 7-inch widescreen colour touch panel in the Harmony GTU range, with an 800 x 480 WVGA display, 12 to 24 V DC supply and IP66 front. It serves as the operator interface of small and mid-size machines and processes. Seven Star LLC supplies the HMIDT351 in Oman and the GCC as an independent supplier based in Muscat.

Decoding the reference: HMI is the Harmony HMI family, DT identifies the GTU series and 351 is the model within the 7-inch group. The datasheet title confirms a 7-inch wide display at 800 x 480 pixels.

Technical specifications of the HMIDT351

Display, power and ruggedness of the HMIDT351

Supply voltage: 12 to 24 V DC power supply. Supply voltage limits: 10.8 to 28.8 V. Display: Colour TFT LCD. Resolution: 800 x 480 pixels WVGA.

The display is a colour TFT with 262144 colours and a backlight life of 50000 hours, with a single-touch resistive panel. Supply is 12 to 24 V DC (10.8 to 28.8 V) with 6.5 W power and 30 A inrush, so it can run from a panel supply or a vehicle-type battery.

The front is rated IP66 and IP67 and NEMA 4X, the cut-out is 190 x 135 mm and the weight is 1.2 kg. Operating temperature is -20 to 60 degrees Celsius, humidity 10 to 90 percent non-condensing, and the product lists UL, CE and other approvals.

Where the HMIDT351 fits among Harmony panels

Harmony GTU is a more modern generation than the GTO and STU lines. Compared with the HMISTU855 (5.7-inch QVGA) it offers a larger and sharper screen, and compared with the HMIGTO3510 it uses a wider supply range.

Screen size drives the HMI choice. A 7-inch panel is large enough for process overview, alarms and trends while small enough for most doors.

Selection checklist for the HMIDT351

• Screen size: 7-inch, 800 x 480.
• Supply: 12 to 24 V DC.
• Cut-out: 190 x 135 mm, depth 67 mm.
• Protection: IP66/IP67 front, NEMA 4X.
• Software: the matching Schneider HMI engineering software and project compatibility.
• Communication: confirm ports for the controller used.

Fitting and configuring the HMIDT351

Fit the panel with the supplied clamps and the gasket, and keep the cut-out edge clean. Connect to the controller via the ports listed in the manual and load the project.

Calibrate the touch screen and check brightness in the real lighting. Back up the HMI project file, because a replacement panel without it requires rebuilding the screens.

Typical applications of the HMIDT351 in Oman and the GCC

In Oman and the GCC, a sealed front helps in washdown, dust and sun-exposed locations. Avoid direct sunlight on the screen where possible since glare reduces readability.

Dimensions, environment and approvals of the HMIDT351

For the HMIDT351, plan the mounting space from the datasheet: 203.6 mm (W) x 148.6 mm (H) x 67 mm (D). The HMIDT351 weighs 1.2 kg. Mounting, derating and enclosure choices follow the environmental data below, which should be compared with the actual panel temperature and the dust and humidity of the site in Oman and the GCC.

Ambient temperature limits in the datasheet: -20 to 60 °C. Relative humidity: 10 to 90 % non-condensing. Ingress protection: Front panel IP66; Front panel IP67. Operating altitude: 2000 m. Vibration resistance: 3.5 mm constant amplitude 5 to 9 Hz IEC 61131-2; 9.8 m/s² 9 to 150 Hz IEC 61131-2. Shock resistance: 147 m/s²IEC 61131-2. Standards listed: UL 508; ANSI/ISA 12-12-01; Class I division 2 CSA C22.2 No 213; CSA C22.2 No 142; IEC 61132-2. Certifications listed for this reference: CULus; RCM; CE; KC; UKCA; UKEX.

Information to send with an RFQ for the HMIDT351

• Full reference and quantity required
• Existing equipment, panel or rack it must fit
• Supply voltage, load or signal details of the application
• Required delivery location and timing
• Whether a spare, a replacement or a new installation

Site conditions in Oman for the HMIDT351

Control cabinets in Gulf plants often run hot, because many sit in outdoor kiosks or in rooms where air conditioning is not always reliable. Before you finalise the HMIDT351, check the permitted ambient range and any derating stated by the manufacturer against the real temperature inside your panel, and leave the recommended spacing around the device so that heat can escape. Long cable runs between the field and the marshalling cabinet are common on large sites, so confirm the signal types, wiring limits and earthing arrangement early in the design.

It also helps to standardise on a small number of part numbers across a project. Keeping a few spare HMIDT351 units on site in Oman shortens recovery time after a fault, and documenting configuration settings makes replacement faster for the maintenance team.
