<p>The present invention relates to a divider, and more particularly, to a demux multiplex board which can turn-on or off a plurality of equipments according to an analog signal inputted through an input unit connected to any one among two or more analog output ports mounted to a control device. To this end, the demux multiplex board of the present invention comprises: an input unit connected to any one among m or more analog output ports mounted to a control device;′n′number of switching units connected to an equipment installed in a field by one to one, and switching the equipment to be turned-on or off; a deep switch for receiving a single mode selection signal to turn-on only one among the switching units according to any one among′n′kinds of different analog signals inputted through the input unit, and a multi-mode selection signal to turn-on one or more among the switching units according to any one among′n′kinds of different analog signals; and a control unit for generating a switching signal to turn-on any one equipment corresponding to the received analog signal among the equipments when the analog signal and the single mode selection signal are received, in order to transfer the switching signal to any one among the switching units, and generating a switching signal to turn-on one or more equipments corresponding to the received analog signal among the equipments when the analog signal and the multi-mode selection signal are received, in order to transfer the switching signal to at least any one among the switching units.</p> |
