Abstract
PURPOSE:To transmit signals between different potentials by a simple unit without using an electric power transformer, etc., by transmitting signals while insulating input signals by use of differential capacitors and FF circuits. CONSTITUTION:Output signals E1-E4 for four circuits generated by pulse outputting circuit 1 are applied to capacitors C1-C4 of insulating capacitor part 21 constituting an differentiating circuit and the outputs of capacitor 21 are applied to differential resistances 22. Differential signals E1'-E4' differentiated by this differentiating circuit are applied to FF1-FF4 of FF circuit 3. Further, common capacitor 5 through which the whole of electric current from the differentiating circuit flows is connected between the negative terminal of outputting circuit 1 and the ground and capacities of this capacitor 5 and capacitors C1-C4 ae selected to prevent FF1-FF4 from malfunctioning, so that while output signals E1-E4 of outputting circuit 1 are insulated from one another, outputs of FF1-FF4 will be transmitted to a unit differing in potential.
