Integrated circuit for relay control by photoelectrically converting control signals from
Enter into l+. (6) is the drive power supply, and the relay (31
and a relay control integrated circuit (m), which supplies 1,000 electrical energy to the relay control integrated circuit (m), and connects this driving power source (6) and the relay control integrated circuit (11) with a photoelectric conversion device (7) to relay the relay. 10,000 electrical energy is supplied to the control integrated circuit (]). The photoelectric conversion device (7) includes an electro-optical conversion element (g) that converts electrical energy into light, such as a light bulb, and an optical-electrical conversion element (g) that converts light into electrical energy, such as a solar cell. and a charging element Q that stores electrical energy and stabilizes the voltage, such as a rechargeable battery.Therefore, the relay control integrated circuit (1) can be electrically isolated from external circuits, and the relay control integrated circuit Fil. does not form a closed circuit with the external circuit, and a high voltage is applied between the relay contact and the external circuit connection terminal of the relay control integrated circuit fi+, causing a leakage current to flow, causing the relay control integrated circuit (1
) can be prevented from being destroyed. Furthermore, even if a surge voltage is applied to the external power supply line that supplies electrical energy to the relay control integrated circuit il+, the surge voltage is not applied directly to the power supply terminal of the relay control integrated circuit fi+, so the surge in the power supply line is suppressed. It can also be protected against voltage.

きるという効果を奏するものである。As described above, the present invention connects a relay control integrated circuit that drives the sushi and a control device that inputs a control signal to the sushi Since the driving power supply that supplies electrical energy to the control integrated circuit and the relay control integrated circuit are connected through a photoelectric conversion device, the sushi control integrated circuit is connected to an external device where high voltage may be generated. This has the effect of electrically insulating the circuit from the circuit and protecting the integrated circuit from destruction due to high voltage.
