LCD240_3VXX

LCD240-3Vxx is a vertical orientated graphic LCD display with optional CAN interface. A resolution of the display is 128x240 pixels. The display is optimized for lift applications. It can be assembled either to the car or to the level. It can present floor markings, direction arrows and the other graphical symbols needed for special indications. Also other information, such as a company logo can be presented. Audible signaling can be done by a standard gong. Gong sounds differently according to direction that car moves. Device is capable to take action in power failure situation automatically. There are two PCB versions available, standard and small.
