Optocoupler PS2505-1 (Photocoupler)

An optocoupler (Opto-Isolator) is useful in isolating two separate circuits while still allowing the input-side circuit to control the output-side circuit. Optocouplers are often used to allow a microcontroller control motors, servos, LEDs, or other circuits or modules that use a different voltage than the logic level voltage on the microcontroller. Another common use is as an electrical noise barrier to isolate sensitive control circuits such as the I/O pins on a microcontroller from loads or circuits that have or can create electronic noise or spikes such as relay coils and motors. This optocoupler has back-to-back LEDs on the input side allowing for either polarity DC or an AC voltage to activate the output transistor.
