Abstract

PURPOSE:To obtain a relay which can be used for both the DC and AC load by giving the electric isolation between the input part and the output part. CONSTITUTION:When no input exists at terminal 2, LED3 is off and photo transistor 4 and 5 are also off. With input applied at terminal 2, the LED emits the light with transistor 4 and 5 turned on simultaneously. In this case, if the load connected to output terminal 6 and 7 is the DC load, the conduction is given via either element 4 or 5 according to the polarity. In the case of the AC load, both elements conduct every half cycle. In such way, both the AC and Dc load can be controlled with the same constitution.
