NE555 DK555 Time delay Relay Module Timer Switch Adjustable Disconnect Module DC 12V Delay Relay Shield 0~10S

Solid State RelaysProduct Description:Size: 6.8 CM*2.1 CM.The main chip: NE555Working voltage: DC12V.Product Features:1.Connect the power supply and delay the closing of the relay (this module only has a delay closing function and does not have a delay disconnection function unless the power is cut off). Specifically, after being powered on, the relay will not immediately draw in and out. At this time, the output terminal of the relay is in the following states: normally open and disconnected from the common, normally closed and connected to the common; After a delay of 1-10 seconds (adjustable delay), the relay will draw and connect. At this time, the state of the relay output terminal is: normally open and connected to the common, normally closed and disconnected from the common; As long as the module is continuously powered on, this state (relay suction state) will remain. Test phenomenon: After power on, the red power indicator light will turn on. After a delay of 1-10 seconds, the relay will pull in and a "click" sound will be heard, and the blue relay pull in indicator light will turn on.2. Delay time adjustable, (0 to 10 seconds).3.Increase the potentiometer can increase the delaytime.4.Increase capacitorCl can increase the delay time.5. With input power indicator.6. With relay indicator light.7.Can control the AC 220V/ 10A look at the device.(Maximum control equipment 2000W).9. With relay freewheeling protection.10. Delay time :T= 1.1RC. For example:Capacitance 100uf Resistance 100K T=1.1 *100000*0.0001=11seconds==========Power Source : DCTheory : Solid State RelayContact Load : Low PowerModel Number : NE555 DK555 Timer Switch Adjustable Disconnect Module Time delay relayVoltage : 12VUse : Purpose
