Input Modules exist in both DIN rail format to be mounted in the enclosure, as well as in a smaller format to be included in the in-wall mounting box of a switch. Via input modules, external contacts such as standard switches, window and door contacts, all kinds of detectors, garage doors and the like are connected to the Qbus system

In a Qbus system, motor control (for shutters, screens,…) can be done centrally (from the electrical distribution board) or decentrally (with a module on the bus closeby the motor).
