8T.8LED
The I/O module LIGA.AIR.8T.8LED.240 is controlled with the Casambi app. It is directly connected to 230VAC
and has 8 insulated inputs for pushbuttons with dry contacts and 8 LED outputs for 48VDC and a total, fused
current of 400mA. The 8 LED outputs show the last selected input.
Each signal output is protected by a diode for the operation of inductive loads such as DC-relays etc.
For this operation, the common diodes cathodes (COM DK) need to be connected to the power source of the
relays. (Shown below in the circuit examples: Connection from positive pole of U2 to COM DK.)
When using multiple power supplies, the supply connected to COM DK must have the highest voltage
of all, or a discharge through the internal diodes will happen and may damage the module.
