CA3062 combined photodetector and power amplifier can produce on/off output by optical signal. The output transistor of IC should be saturated or closed, prevent the temperature from rising. When the light of IR LED falls on the optical input terminal of IC, complementary output can select the load which is normal open or normal off. After blocking the light path, it will produceopposite load situation.
