NE555 DC 12V delay Closure Module Relay Module delay Control Adjustable Controller

RelaysProduct ParametersSize: 61*17mmMain chip: NE555Working voltage: DC 12VProduct FeaturesTime delay pull-in of power relay. Specifically, after providing 12V power to the relay, the relay will not close immediately. The state of the output end of the maintenance appliance is: normally open and public disconnect, normally closed and public on-off; After a delay of 1-10s (adjustable), the relay is closed. At this time, the state of the output end of the relay is: normally open and public on, normally closed and public off; As long as the module is powered on, this state will remain without a cycle.Adjustable delay time (0-10 seconds)Adding potentiometers can increase the delay timeIncreasing capacitor C1 can increase the delay timeIt has an input power indicatorWith relay pulling indicator lightCan control ac 220V/10A below the equipment. (Maximum control equipment 2000W)With relay continuation protection.Delay time formula: T=1.1rc. For example: Capacitance 100UF resistance 100K T=1.1*100000*0.0001=11 secondsNote: there are anti-reverse connection diodes on the back to protect the circuit.
