Additional Details: The PS2626L-E3 SSR typically operates by using an LED to activate a photosensitive semiconductor switch (such as a MOSFET or TRIAC). The input current is used to drive the LED, and the light emitted by the LED turns on the semiconductor switch, completing the circuit between the output terminals. The output current rating and voltage handling capabilities vary; the specific datasheet should be consulted for accurate values.
