Description
The
KNX B4 Universal Interface
is a 4-fold KNX binary input to sensor contacts and
to control/switch/operate KNX devices via classical conventional switches and push
buttons. The input module is suitable to process binary signals of potential-free con-
tacts. Due to its small housing (diagonal of 50 mm)
KNX B4 Universal
finds enough
room in a flush-mounted box (Ø 60 mm) behind the switch. The connecting cable pairs
of 28 cm can be extended up to 10 m when twisted.
Designed for KNX-enabling of conventional switches and push buttons,
KNX B4 Uni-
versal
provides a 3.3 V sensing voltage for contact scanning. All usual input functions
like switching, dimming, shutters, blinds control, counter and scenes can be used in a
common way.
Due to its small housing with a diagonal of 50 mm,
KNX B4 Universal
finds enough
room in a flush-mounted box (Ø 60 mm x 40 mm) behind the switch. The connecting
cable pairs of 28 cm can be extended up to 10 m when twisted.
