4 universal binary/digital inputs for KNX
- - Configuration as switch, dimmer, shutter/blind control, counter, scene
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.
- 4-fold KNX binary input module suitable for potential-free contacts
- Contact scanning of window contacts, door contacts etc.
- KNX-enabling of classical conventional switches and push-buttons
- Small dimensions suitable for flush mounting
- Simple low-cost device
- Low current consumption
- Internal supply via KNX TP bus line
- Average input sensing voltage of 3.3 V
- NO or NC contact operation
- Detection of short and long button press
- Channels separately configurable
- Interlock function
- Large number of KNX input applications: Sun protection (one-button and two-button shutter) Dimming (one-button and two-button dimming) Switch (short/long button press) Scene (8-bit with/without saving function, 1-bit) Counter (8-bit, 16-bit, 32-bit) Send value (percent, angle, temperature, 2-bit, 8-bit, 16-bit)
- Push-button for programming the Individual Address
- Can be used with ETS 3.0d and higher
