Additional Details: The PS2651 typically consists of an LED on the input side and a phototriac or MOSFET on the output side. When current is applied to the LED, it emits light, which activates the phototriac or MOSFET, closing the circuit between the output terminals. Specific electrical characteristics, such as input voltage range, output current rating, and isolation voltage, vary depending on the exact model. Consult the datasheet for precise specifications.
