Solid State Relays

Solid state relays (SSR) are special type of relays which use semiconductor switching devices to switch high voltage. Unlike electro-mechanical relays, SSRs use semiconductor switching elements such as thyristors, triacs, MOSFETs, transistors (IGBTs) for switching the electrical loads. These solid state relays offers several advantages. They can handle higher switching frequency and they don’t suffer from contact wear and tear like traditional electro-mechanical relays. SSRs are widely used for applications such as motor control, home automation and process automation.
