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

The range of Qbus dimmermodules goes from standard dimmers to dim halogene or incandescent lights over universal dimmers for any load to 0/1-10V dimmers to dim analogue circuits or energy savings lamps
