路。 In a relay circuit that drives multiple relays with the same power source, the contacts of each relay are connected in parallel, a load is connected to the common connection point, and a contact signal is detected to detect that one of the contacts has failed. At the same time, a control means is provided that notifies the failure status of the relay, forcibly turns off the contacts of the relay, and allows the other relays to continue operating, and connects the AC power supply with the load and the input side of the diode bridge. A failure prediction function characterized in that series circuits are connected in parallel, the positive terminal side of a diode bridge is connected to one end of the above contact via a backflow prevention diode, and a contact signal is taken out from one end of the connection. relay circuit.
