Schneider Electric HMIDT952 Harmony GTU 18.5in Touch Display

HMIDT952: 18.5 inch Harmony GTU touch smart display, FWXGA

The HMIDT952 is a Harmony GTU flat-screen touch display from Schneider Electric. Its commercial name is 19W Touch Smart Display FWXGA, while the datasheet states a display size of 18.5 inch, a colour TFT LCD at 1366 × 768 pixels and 16 million colours. The panel uses multi-touch projected capacitive technology and carries an IP66/IP67 front, which puts it in a different class from the resistive GTO and ST6 panels in the same lane. Seven Star LLC supplies the HMIDT952 in Oman and the GCC as an independent supplier based in Muscat.

Two things are worth stating up front. First, the datasheet describes a display unit; its drawings show it with a box module, and the Premium Box HMIG3U belongs to the same Harmony GTU range, so confirm the pairing that your project needs. Second, the datasheet lists a touchscreen resolution of 2048 × 2048 and an aspect-ratio field that does not match the pixel format, so rely on the 1366 × 768 pixel figure for screen design.

Power and thermal data of the HMIDT952

The supply is 12 to 24 V DC with limits of 10.8 to 28.8 V and a stated consumption of 19 W. Inrush current is 30 A, which should be considered when several displays share one DC supply and are switched on together. Cooling is by natural convection, with no fan in the datasheet description.

The datasheet specifies 0 to 55 °C in operation, but it adds a mounting rule: when the display is installed at an incline of more than 30°, the ambient temperature must not exceed 40 °C, and forced air cooling may be needed. In a Gulf control room or cabinet this is the point to design for rather than the headline figure. Vibration data is 3.5 mm constant amplitude at 5 to 9 Hz and 9.8 m/s² at 9 to 150 Hz, with shock resistance of 147 m/s² and ESD immunity level 3.

Typical uses of the HMIDT952 in Oman and the GCC

A large widescreen display of this kind suits control rooms, motor control centre doors, utility switchrooms, packaged plant and desalination or water-treatment operator stations where several process pages need to be visible at once. IP66/IP67 on the front allows washdown near the screen, but the rear is for cabinet interiors. Heat is the main design question in the Gulf: keep the mounting angle, the cabinet temperature and the 40 °C incline rule in view.

Technical specifications of the HMIDT952

Installation and care of the HMIDT952

Mount the display flush with the clamps tightened evenly and the front gasket clean, since the IP66/IP67 front rating depends on a uniform seal. Provide DC supply protection suited to a 30 A inrush, and route the USB leads without strain. Clean the glass with a soft damp cloth and avoid abrasive cleaners. Keep the project files for the connected controller and the display safely archived so that replacement is quick.

Selection checklist for the HMIDT952

• Confirm that the application needs a large 18.5 inch capacitive screen rather than a resistive one.
• Check the supply: 12 to 24 V DC, 19 W, 30 A inrush.
• Decide on the box module or controller side and confirm compatibility within Harmony GTU.
• Check door cut-out of 465 x 319 mm and the weight of 6.8 kg.
• Confirm that the 40 °C limit for inclined mounting suits the cabinet.

Panel cut-out and fastening for the HMIDT952

The panel cut-out is 465 (+1/−0) × 319 (+1/−0) mm for plates 1.6 to 5 mm thick, with a corner radius of 3 mm maximum. The unit measures 483 wide, 337 high and 69 mm deep and weighs 6.8 kg, so the door must carry a substantial load and the datasheet shows installation fasteners with a rotation area that needs free space around the cut-out. Check that the stiffness of the door is enough, especially for hinged doors on large cabinets.

Capacitive multi-touch on the HMIDT952

Projected capacitive touch behaves differently from the resistive layers used on the GTO and ST6 panels. It responds to a light fingertip contact and supports multi-touch, and the datasheet quotes 50 million touch cycles. A brightness sensor is listed as an available function, so the backlight can follow ambient light in a control room. Operators who work in thick gloves or who press with tools should be asked how they actually use the screen, because capacitive sensing has different glove behaviour from resistive film; check this with a sample if it matters.

The 1366 × 768 picture is a widescreen format, so screens designed for older 4:3 panels need to be re-laid out rather than stretched.
