ることができる。(Effects of the Invention) As explained above, the f3A of this invention inserts a thyristor between the connection point of the relay control device and the relay drive winding and the ground, and connects the power output for the control device and the output of the relay control device. When an abnormality is detected in either of the relays, the thyristor is made conductive and current continues to flow through the relay drive winding. This prevents the power from being turned on or stopped due to failure of the control device or its power supply. , the reliability of the power supply circuit can be increased. Furthermore, by manually switching the circuit through which the relay drive winding current flows, the control device and its power source can be maintained independently even when the relay cannot be turned off while the load is in operation.
