Description

The device has 4 channels which can be parameterised as inputs or outputs by selecting the application program.
Using the colour-coded connecting cables, it is possible to connect conventional push buttons, potential-free contacts or LEDs. 
Series resistors for external LEDs are integrated in the device.
The universal interface is inserted in a flush-mounted combined wall and joint box, 60 mm.
Connection via bus connection terminal supplied.
The following list provides an overview of functions:

  • Switching and dimming of lighting (also for 1-button operation)
  • Operation of blinds and roller blinds (also for 1-button operation)
  • Sending of arbitrary values, e.g. temperature values
  • Control and storing of light scenes
  • Triggering an electronic relay for control of electro-thermal valve drive for heating valves
  • Control of an LED (with flashing function and time limitation) for feedback of an operation
  • Operation of different loads by multiple push button actions
  • Operation of several loads in a fixed switching sequence
  • Counting of impulses and operations
  • Reading out of technical contacts (e.g. relays)

Each channel of a device can assume one of the functions described above.
