modname=ckeditorFeatures:1. Turn on the power, and the relay will delay closing (this module only has a delay closing function and no delay opening function, unless power is cut off). Specifically, after being powered on, the relay will not immediately draw on, and the output terminal of the relay will be in the following states: normally open and common disconnected, normally closed and common conductive; After a delay of 1-10s (adjustable delay), the relay will activate. At this time, the output terminal of the relay will be in the following states: 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 constant. Test phenomenon: After powering on, the red power indicator light will light up. After a delay of 1-10 seconds, the relay will engage and a "click" sound will be heard, and the blue relay engage indicator light will light up 2. Adjustable delay time (0-10 seconds) 4. Adding a potentiometer can increase the delay time 5. Increasing the capacitance C1 can increase the delay time 6. With input power indicator light 7. With relay closing indicator light 8. It can control equipment with AC voltage below 220V/10A. (Maximum control equipment 2000W) 9. Equipped with relay continuous current protection. 10. Delay time formula: T=1.1RC. For example, capacitance 100uf, resistance 100K, T=1.1 * 100000 * 0.0001=11 Vehicle equipment-delay to prevent car ignition, prevention of high sudden current to burn components and devices. This is a 5V / 12V Conduction delay relay module This is a brand new and high quality delay turn-on module. the use of high-performance timing CPU design. the power indicator LED and switch trigger timing indication LEDs; The output can be connected to AC 250V 10A DC 30V 10A load; There is the chronopotentiometry regulation time, adjustable from 0 to 10 seconds by default, or by changing the capacitance adjustment time longer Specification: 1.Module based on: NE555 chip. 2.Delay modue:delay connect module 3.Input voltage: DC 5V / 12V 4.Control voltage: AC 0~250V / max. 10A, DC 0~30V / max. 10A the operating voltage: 12 volts DC; (otherwise 5V optional) 5.Max. load: 2200W Main Chip (NE555) Characteristics: 1.Timing from microseconds to long hours 2.Simple circuit design 3.Precision Pulse Generation / Timing, 4.Adjustable Duty Cycle
