The BI08H01KNX binary input device is a DIN-rail mounted device with 8 inputs for 100-230 V AC voltage. It can detect both states (voltage
present or not present) and voltage pulses. Therefore, it can be used, for example, to monitor voltages (if the mains voltage is present), to detect switching or system states, to detect the change of state during the switching on or off of a voltage (if a switch or button has been operated, if only a switch or button has been operated). Or more simply for the classic functions of on/off / dimming of lamps or dimming control.
