The ASSR-1219 is typically controlled by a low-voltage DC signal applied to the input. The internal IRED emits infrared light, which is detected by the output detector, causing it to switch on. The output can then switch a higher voltage and current load. The ASSR-1219 offers several advantages over electromechanical relays, including faster switching speeds, longer life, and higher reliability.
