Description
The KNX B4 Universal interface is a 4-fold KNX binary input. It is used for status detection of contact sensors and for controlling/switching/regulating KNX bus devices with classic conventional switches and push-buttons. The input module is suitable to process binary signals of potential-free contacts and provides a 3.3 V sensing voltage for contact scanning.
KNX input functions like switching, dimming, shutters, blinds control, counter and scenes can be used in the common way. Due to its small housing (diagonal of 52 mm) KNX B4 Universal finds enough room in a flush-mounted box (Ø 60 mm) behind the switch.
