(Solid State Relay, abbreviation: SSR) solid state relay is a non-contact relay that is controlled by a semiconductor to control the load to flow through a solid state switch. After receiving low-voltage DC or AC signal input, it then conducts high-voltage, high-power output current, and isolates the output and control. High power output current.

INPUT is DC 4-32V, OUTPUT is up to AC 380V, 25A
Can be used to replace Electromagnetic relays during fast ON/OFF cycles. Widely used in digital program control devices. A typical SSR has a lifespan of up to 100,000 switching cycles.
