The IO44B02KNX device is equipped with 4 inputs for dry contacts, which can also be configured as outputs for driving LEDs and 4 16A relay outputs for controlling loads. The 4 input channels are dedicated to interfacing dry contacts, e.g. for sensors, traditional buttons, etc. They can be configured and have integrated on/off control functions, dimmers, shutters and scenario recall. The relay outputs have timing functions, on/off delay as well as logic and scenario functions. The outputs can act in an interlocked manner and be dedicated to driving 2-pipe/3-speed or 4-pipe/2-speed fan coils. The product is also intended to be dedicated, in its modular form, to DIN rail installation in LV electrical distribution panels.
