DC 5V 12V Time Delay Relay NE555 Timer Control Switch Car Pulse Generation Duty Cycle(12V)

relaysDC 5V 12V Time Delay Relay NE555 Time Relay Shield Timing Relay Timer Control Switch Car Relays Pulse Generation Duty CycleProduct features:adjustable delay time,(1~10 seconds) adding potentiometer can increase delay time increase capacitor C1 can increase delay time has input power indicator light has relay pull-in indicator light can control AC 220V/10A-down equipment. (Maximum control device 2000W) Relay with freewheeling protection.Product parameters:main chip: NE555 working voltage: DC 12V/5V size: 6.8CM * 2.1CM 1. power on relay delay closing. Specifically: after supplying 12V/5V power to the relay, the relay will not suck immediately. the state of the output end of the electrical appliance is: normally open and publicly disconnected, normally closed and publicly connected. after a delay of 1~10s (adjustable), the relay sucks and. at this time, the state of the output end of the relay is: normally open and publicly connected, normally closed and publicly disconnected; As long as the module is continuously powered, this status will-be guaranteed. 2. delay time adjustable,(1~10 seconds) 3. adding potentiometer can increase delay time 4. increasing capacitor C1 can increase delay time 5. with input power indicator 6. with relay pull-in indicator 7. can control AC 220V/10A-down equipment. (Maximum control equipment 2000W) 8. With relay freewheeling protection.Applicable occasions:1. Delay the on-board equipment to prevent excessive current from burning the on-board equipment when the car is on fire. 2. the need for sequential start-up occasions, to prevent multiple devices at the same time start the current is too large to burn electrical appliances. Features:1. length * width = 52mm * 16mm, 2. module working voltage 12V 3. module controllable: 10A 250VAC (AC),10A 30VDC (DC) below load. 4. time can be adjusted by potentiometer default 0. 25 seconds, need longer time, 5. delay time : T = 1.1RC. For example: capacitor 47uf resistor 500K T = 1.1*500000*0.000047=25.85 seconds.
