Additional Details: The PS2701-1-3 generally operates by using an LED on the input side to activate a photosensitive semiconductor switch, typically a MOSFET or TRIAC, on the output side. When current is applied to the LED, it emits light, which triggers the semiconductor switch, completing the circuit between the output terminals. Consult the datasheet for specifications related to input voltage range, output current rating, and isolation voltage.
