Filed: 1980-12-29
Abstract: PURPOSE:To prevent the malfunction of a zero cross type contactless relay, by connecting a reed relay between control input terminals of a zero cross type  contactless relay and controlling the gate of an SCR with the contact. CONSTITUTION:When a control input voltage is not applied to a light emitting diode Dh, no reed relay Ry is energized, and since a normally opening contact NO is at off-state, even if a photosensing pulse oscillating element P is broken over through rapid application of the power supply voltage, no SCR turns on because the value of a resistor Rb is great, and this zero cross type contactless relay is not malfunctioned. On the other hand, if a control input voltage is applied to the diode Dh, since the reed realy Ry is energized and the contact NO is closed, the current of the element P flows through the contact NO to the gate of the SCR, which is normally turned on.
