description PROBLEM TO BE SOLVED: To provide an optical gate circuit which enables easy detection of a failure on a one system even when a dual system outputs optical gate signals concurrently.SOLUTION: An optical gate circuit 1 forms a dual system configured of two half-systems, which comprises: two light-emitting elements 11a, 11b each operable to generate an optical gate signal; a light splitter 12 which synthesizes the optical gate signals generated by the two light-emitting elements 11a, 11b, and branches a resultant optical gate signal into a plurality of optical gate signals in order to output to a plurality of optical trigger thyristors 31; and a failure detector 2 operable to detect a failure of one half-system of the dual system based on a quantity of light of one of the plurality of optical gate signals resulting from the branching by the light splitter 12.SELECTED DRAWING: Figure 1 【課題】 二重系で同時に光ゲート信号を出力する場合でも片系の故障を容易に検出することのできる光ゲート回路を提供することにある。【解決手段】 光ゲート回路1は、二重系を構成し、それぞれが光ゲート信号を発生させる2つの発光素子11a,11bと、2つの発光素子11a,11bからそれぞれ発生した光ゲート信号を合成し、合成された光ゲート信号を複数の光トリガサイリスタ31に出力するために複数の光ゲート信号に分岐する光スプリッタ12と、光スプリッタ12により分岐された複数の光ゲート信号のうち1つの光量に基づいて、二重系のうち片系の故障を検出する故障検出器2とを備える。【選択図】図1
