The PS9115-F3-A is an optocoupler classified as an optoisolators - logic output. It works between a low voltage digital circuit, where the input power is often TTL compatible, and a higher voltage analog circuit, such as relays and actuators. The input of the optocoupler is provided with a current of a few mA that is used to control the output voltage of the optocoupler at the 5V TTL-compatible output.

The PS9115-F3-A is a small package optocoupler, with an integrated spruce and two phototransistors side by side on one substrate. The spruce includes an LED and two photodetectors, one NPN output and one PNP output, and a single diode shorting the two phototransistors. The NPN output is used for low voltage logic inputs while the PNP output is used for high voltage output.

The PS9115-F3-A is used in digital applications such as switching relays and controlling motors. The optocoupler keeps the digital logic signals isolated from the analog power lines. The five-volt output of the optocoupler provides a logic-high voltage to the relay and turns on the motor, while the logic-low voltage keeps the relay and motor off. This way, the optocoupler keeps the low voltage digital logic away from the high voltage power lines.

This device is also used in measuring devices, digital display equipment and analog processing methods in order to provide isolation between the analog and digital electronics. For example, with its high-speed switching action, the PS9115-F3-A can be used to measure temperature, humidity, pressure and other parameters using temperature probes with thermopiles connected to the optocoupler.

The typical operating voltage of the PS9115-F3-A is 5V. When the input is a logic-level input lower than 2.4V the LED does not turn on. When the voltage of the logic signal exceeds 2.4V the LED turns on, and the output voltage of the optocoupler rises from 0V to 5V. The LED turns off when the logic signal drops below 0.4V and the output voltage of the optocoupler stays at 5V.

The PS9115-F3-A is primarily used for digital circuit isolation and signal conversion applications, especially in devices and machines where it is required to keep two circuits or systems electrically isolated from each other, for example between a digital and an analog circuit. The PS9115-F3-A is also used in a wide range of electrical systems from domestic appliances to industrial machinery.
