ABB US/U12.2

Universal Interface, 12-fold, FM

Product code: US/U12.2
The Universal Interface has 12 channels which can be parameterised as inputs or outputs, e.g. for connection of conventional push-buttons or LEDs. The LEDs are supplied by the device (1.5 mA), the series resistances are integrated.
Price (Excluding GST)


The device has 12 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.
