Equipped with a 7-inch TFT LCD color display with 800 x 480 pixels and LED backlight, the compact multi-touch operating panel (PCT) comes standard with EDGE2 technology processor, 256 MB internal program and data memory (DDR3 RAM), as well as 512 MB NAND flash. A USB 2.0 and an M12 interface for power supply and Ethernet are integrated.

Like all Sigmatek HMIs with a processor, this multi-touch panel also supports OPC UA communication.

On the front side, the ETT 7321 is designed in protection class IP65, on the back side it complies with IP54. The advantage of the carrier arm mounting is that the operator can align the panel to always keep his application in view.

With the elegant glass display enclosed by a 5 mm aluminium frame in black and thus more robust, the fanless HMI also has a lot to offer visually. The creation of the visualization is comfortable and very flexible by using the object-oriented engineering tool LASAL.
