Solid State Relay

The solid state relay (also called SSR, SS Relay, SSR relay or SSR switch), is a kind of non-contact electronic device that functions like a traditional electro-mechanical relay(EMR). With the development of the technology, the traditional mechanical relay can not meet the needs of most of the new equipment. And  because of its advantages, the solid state relay is gradually replaced the mechanical relays in various fields.>>More about solid state relays>>
