This is the new push-button interface equipped with outputs for monitoring the warning LEDs found in modern domestic series.

The traditional functions previously described for the BX-4XIO device are complemented by a series of communication objects for monitoring warning lights.

The device is equipped with a 15 cm long cable and 4 pairs of wires for direct connection to the push buttons. The wires have different colors to facilitate the recognition of the channels.
Inputs are individually configurable with ETS to perform the desired function by the designer.
The device provides control functions for load control, opening and closing of shutters, adjustment of a light source and selection of scenarios. Some of these functions exploit the possibility of recognizing the prolonged closure of the auxiliary contact to carry out the command desired.
