Solid State Relays

Characteristics of Solid State Relays No mechanical parts Galvanic separation between control and load circuit by opto-coupler Semiconductor components like triacs, thryristors, alternistors or MOS-FET's in the output Advantages of SSR's against Electromechanical Relays Nearly unlimted life expectancy Low control power, direct interface to microcomputer or PLC No contact bounce No sparks No mechanical contact wear Intensitivity to shock, vibration and mechanical forces as well as severe environmental conditions Comus thryristor SSR's are manufactured using DCB-Technology (direct copper bonding) and are approximately 100 times more resistive to temperature cycles than conventional SSR's.
