Last but not least, it can be used to protect against various over-voltage conditions in AC/DC motor driven devices.

The working principle of PS2815-4-F3-A optoisolator involves the conversion of an electrical signal into optical signal with the help of internal photo diode. The optical signal is then transmitted across an output photodiode which then receives the optical signal and converts it back to electrical signal. This optoisolator can effectively isolate Analog and Digital signals from each other with a very high degree of accuracy. The optoisolator input is connected to either an AC or DC voltage source, while the output circuit is connected to the output device which can be either an actuator, a motor circuit, etc. The optoisolator works in such a way that when voltage is applied to the input port, it is converted into light energy, which is then transmitted over the output photodiode. This light activates the output Photodiode which then generates an electrical signal that is used to control the output device.

In summary, PS2815-4-F3-A optoisolator is a transistor, photovoltaic output device that can provide electrical isolation between input and output. This optoisolator can find application in medical equipment, military, industrial robots, logic control systems and in AC/DC motors. In its working principle, it uses internal photo diode for converting electrical signal into optical signal, that is then transmitted to output photodiode and converted back to electrical signal for controlling the output device.
