ようにしたことを特徴とするソリツドステートコ
ンタクタの主回路素子開放の故障検出回路。 A control signal input that controls on/off of the solid-state contactor and a load voltage of the load driven by the solid-state contactor are input as signals, and when the control signal is on, the main circuit elements of the solid-state contactor are opened. In the detection circuit that detects a failure in the condition, a lock time is provided to lock the detection operation, which is the time from when the control signal is turned on until the solid-state contactor becomes conductive and the circuit for detecting the load voltage operates. , a single-phase operation state in which one of the three circuits of the main circuit element of the solid state contactor is open;
and a fault detection circuit for an open main circuit element of a solid state contactor, characterized in that it is capable of detecting a non-conducting state in which two or more circuits are open.
