特徴とする情報伝送装置。Consisting of a master station and a plurality of slave stations that are connected to each other by a line, each of the slave stations detects the opening and closing of contacts corresponding to the monitoring information by the flow of current, and generates information assigned to each slave station. A plurality of tone signals each having a different frequency are serially combined to transmit information between the master station and each slave station, and power is supplied from the master station to each slave station. In the information transmission device, each slave station is provided with a pulse generator that generates a pulse of a certain time width when specified by information from the master station, and a switch that conducts current to the contact in response to the pulse. An information transmission device characterized by:
