Solid State Relay Module MITSUBISHI SF15DYZ-H1-4 4-7V 15A

A solid-state relay (SSR) is just what it sounds like; an 1C that acts like a mechanical relay. They allow you to control high-voltage AC loads from lower voltage DC control circuitry. They accomplish this by using infrared light as the ‘contact,’ a solid-state relay is really just an IR LED and a photometric sealed up into a little box. Compares with the traditional mechanical relay, the Solid State Relay (SSR) has many advantages: it has a longer life, with a much higher turn on/off speed and no noise. Besides, it also has better resistance to vibration and mechanical shock and better moisture-proof performance. MITSUBISHI 15A Solid State Relays Module is an industrial SSR Relay.
