The IDEC RSSDN-10 A is a robust solid-state relay designed for surface mounting, capable of handling 10 A loads with an input range of 4-32 VDC and output from 48-660 VAC. It features a dual SCR output for reliable switching and a direct bond copper substrate for efficient heat dissipation. The relay includes internal transient protection with a built-in snubber, ensuring EMC compliance to level 3 standards. With 1200V blocking voltage and 4000V optical isolation, it offers zero crossing turn-on to minimize electrical noise during operation. An optional finger safe cover enhances user safety.
