>> Solid State Relays <<

Sai Control System offers wide range of solid state relays. Solid State relay is a static electronic switch
unlike in an electromechanical relay where switching takes place between two moving contacts, switching
in SSR takes place across the junction of semiconductor device. Devices are Triac or Thyristor for Ac
switching & Transistor for DC switching.

In most SSRs galvanic separation is achieved by Optocouplers equipped with integrated trigger circuit. (optoriac) provide the switching function required for the corresponding load type.
