Contactless relay

Abstract

Abstract PURPOSE:To prevent the occurrence of malfunction in the control of a reversible motor or the like by providing a circuit inhibiting the operation of the opposite function comprising two prescribed switching function sections. CONSTITUTION:A circuit from an input side light emitting diode 3 to an output terminal of both electrodes of a Triac 10 is constituted as a switching function section 20. Furthermore, a circuit from a light emitting diode 4 at the input side to the output terminal of both electrodes of a Triac 18 is constituted as a switching function section 21. The light emitting diodes 3, 4 are driven in the opposite function operation inhibiting circuit 22 comprising the switching function sections 20, 21 by a common input signal. In inputting a current signal between input terminals 1 and 2 to light the light emitting diode 3, since the Triac 10 is turned off, a part between output terminals 11, 12 is turned off. Thus, both the switching function sections 20 and 21 are not simultaneously turned on in the titled contactless relay 51.
