The device has four channels, which can either be parameterized as inputs or outputs in the ETS program.
Using the colour-coded connecting cables, it is possible to connect conventional push buttons, floating contacts or light-emitting diodes.
The scanning voltage for the contacts and the supply voltage for the LEDs are made available by the device.
Series resistors for external LEDs are integrated in the device. The Universal Interface is inserted in a conventional 60 mm combined wall and joint box.
The bus connection is carried out via the bus-connecting terminal supplied.
