Main chip: NE555. Delayed Disconnect disconnection. Relay closure indicator. With relay current protection. eg: capacitance 100uf resistance 100K. 1, turn on the power relay delayed suction. 4, successfully triggered again after a delay of 0-25 seconds after the relay is disconnected, note: if the trigger signal - straight there will be kept closed until the trigger signal disappears, the module began to delay the timing, the delay of 0-25 seconds to disconnect.
