4 universally usable binary/digital inputs for KNX.
Configuration as a switch, dimmer, shutter/blind control, counter, scene.
The KNX B4 Universal interface is a 4-fold KNX binary input. It is used to detect the status of contact sensors and to control/switch/regulate KNX bus participants with classic, conventional switches and buttons. The inputs are suitable for floating contacts and provide a query voltage of 3.3 V for contact detection.
All typical KNX functions such as switching, dimming, roller shutters/blinds control, counters and scenes are available. Due to the small housing (52 mm diagonal), the KNX B4 Universal finds enough space in a flush-mounted box (Ø 60 mm) behind the switch.
