Abstract

PURPOSE: To prevent malfunctions of this relay unit by inserting a Zener diode between the collector and the base of a transistor and by connecting optically a LED, which is controlled by a control input voltage, to a photosensitive pulse oscillation element.
CONSTITUTION: Current detection resistance R1 is inserted between the T1 pole and gate G of Triac T which switches as AC load, and SCR Sc is connected between the T2 pole and the gate through full wave rectifier circuit Ds. The collector and the emitter of photosensitive pulse oscillation element P are connected between the anode and the gate of SCR Sc, and transistor TrQ is connected between the gate of element P and the cathode or the gate of SCR Sc, and Zener diode Z is inserted between the collector and the base of TrQ, and LED Dh controlled by a control input voltage is connected to element P optically. Then, malfunctions of this relay unit can be prevented by flowing a current, which is considerably larger than the current for only Zener diode Z, to the gate of element P.
