Combi I-O devices are devices for communication and interaction of an information system with their users or other systems by sending and receiving information. Inputs are, for example, signals fed in by user or binary inputs or other received data, outputs are sent by the system or represent values converted by actuators into actions. In this eibabo category, you will find, for example, KNX devices with multiple functions from ABB, Berker, Busch-Jaeger, Gira, Hager, Issendorf, Jung, Lingg & Janke and many more manufacturers, who, usually, only present individual devices. For example, actuators with switching and blind channels, KNX actuators with integrated binary inputs, KNX push button interfaces with outputs for LED control systems or special KNX room controllers with a wide range of special functions.
