Glass info module with four capacitive buttons with 2.8-inch graphic display in white, black or champagne.


The LCN-GT4D is an info keypad with TFT display. It is designed for mounting on a flush-mounted box and can be firmly anchored to the wall with a special mounting plate. The connection is made via the I-connection of the enclosed LCN power supply LCN-NUI and an LCN bus module from version 140719 (July 2010). A temperature sensor is integrated in the LCN-GT4D sensor keypad. Thanks to a resolution of 0.1 °C and adaptive averaging, it delivers practically noise-free measured values. A bar graph can be displayed on the left and right of the display, in which up to two values can be marked. The bar graphs are designed in the parameterization with the LCN-PRO, up to colors and gradients.

The four capacitive sensor surfaces are arranged behind a 4 or 3 mm thick glass front. A light touch on the surface is enough to trigger various functions. In addition, the LCN-GT4D offers a Corona® light ring with white LEDs for wall illumination. This allows the LCN-GT4D to be operated comfortably even in low ambient light. The sensor surfaces can be digitally labeled on the display. Different types of display are possible on the display. Icon row: A maximum of six icons can be displayed in the top line of the screen. These symbols are assigned to a binary input, relay, output or logic function and react to its status message.

A maximum of 19 to 23 characters can be entered in each of the three text lines (autoscroll function) if the single line height is used. Text lines 1 to 3 can also be set to double line height and then occupy two lines. Key labeling: A label text can be entered for the four keys. The text can be max. 25 characters long (without autoscroll function). Alternatively, the display can show four lines of text when the key label is not needed. The LCN-GT4D speaks eight languages: German, English, French, Spanish, Polish, Turkish, Russian and Arabic, which can be switched during operation.
