Abstract
Because a semiconductor relay system of this invention comprises an across-element voltage detecting circuit which delivers an across-element voltage detection signal depending on the presence/absence of an across-element voltage exceeding a predetermined threshold; an element driving circuit for delivering an element driving signal in response to a control input signal; a logic-based judgement circuit for delivering a logic-based judgement signal depending on the presence/absence of an across-element voltage detection signal; and a filtration circuit for removing a logic-based judgement signal of external disturbing elements to produce an element safety check signal, it is possible to reliably detect the disorder of a triac
