輸入電路
按輸入電壓的不同類別，輸入電路可分為直流輸入電路，交流輸入電路和交直流輸入電路三種。有些輸入控制電路還具有與TTL/CMOS兼容，正負(fù)邏輯控制和反相等功能，可以方便的與TTL,MOS邏輯電路連接。
對于控制電壓固定的控制信號，采用阻性輸入電路?？刂齐娏鞅ＷC在大于5mA。對于大的變化范圍的控制信號（如3~32V）則采用恒流電路，保證在整個電壓變化范圍內(nèi)電流在大于5mA可靠工作。
隔離耦合
固態(tài)繼電器的輸入與輸出電路的隔離和耦合方式有光電耦合和變壓器耦合兩種：光電耦合通常使用光電二極管—光電三極管，光電二極管—雙向光控可控硅，光伏電池，實現(xiàn)控制側(cè)與負(fù)載側(cè)隔離控制；高頻變壓器耦合是利用輸入的控制信號產(chǎn)生的自激高頻信號經(jīng)耦合到次級，經(jīng)檢波整流，邏輯電路處理形成驅(qū)動信號。
