Abstract

PURPOSE:To decrease the number of the amplification step for the receiving circuit and thus to realize a miniature size and the low power consumption for the reception circuit which is controlled by the control signal transmitted via the power line and carries out the multiple control for the load. CONSTITUTION:Receiving circuit 1 connects the commercial power supply element to power line 4 via block filter 2 and is driven by the control signal given from transmitting circuit 5 connected to line 4. Coupler 8 connected to line 4, limiter circuit 9 connected to coupler 8 and reception signal detector circuit 10 are installed to circuit 1. In addition, the following units are provide: relay driving circuit 12 to supply the output of circuit 10; relay circuit 13 to be driven by circuit 12; and load 7 to be actuated by circuit 13. Then pulse generator circuit 11 is connected to power line 4, and rectifier circuit 14 is added to supply the output voltage to circuit 10, 12 and 13 respectively. Thus, a receiving circuit is constituted.
