The latest version of Graf-Syteco's K2 series keypad modules can be freely programmed and can therefore also perform simple control tasks. The keyboards, which are connected to automation devices via a CAN interface, then not only work purely passively, but can also trigger various actions when a key is pressed, depending on the status of the machine. The keypads have e1 approval and meet protection class IP65. Depending on the type, the modules consist of four or five short-stroke keys and one or two digital potentiometers. The available space is optimally utilized, as the modules can be installed both vertically and horizontally. The integrated keypad lighting, the brightness of which can be dimmed, makes the keypads easy to read even in the dark.
