LIYUDL 12V NE555 Oscillator Delay Adjustable Timer Relay Switch Module 0-10 Second

Description

Description: 100% brand new and high quality Short description One size: 6.8 CM * 2.1 CM Second, the main chip: NE555 Third, the operating voltage: 12 V Four features: 1. tensile power delay relay. Specifically: 12V power supply for relay, relay not immediately absorbed and relay outputs status are: disconnected normally open, normally closed and public driving; Wait until the delay 1-10 s (adjustable), the suction relay and, this time, the output status relay is: normally open and public driving, normally closed and public disconnected; While uninterruptible power supply module, this state will be maintained. 2. the delay time is adjustable, (0 to 10 seconds) 4. to increase the potential can increase the delay time 5. increasing the capacitor C1 can increase the delay time 6. with input power indicator 7. with relay indicator 8. the AC 220 V / 10A can be controlled on the equipment. (Maximum control of equipment 2000 W) 9. with free wheel protection relay. 10. the time delay formula: T = 1.1RC. For example: a capacitor resistance 100 uf 100 K T = 1.1 * 100000 * 0.0001 = 11 seconds Applications: 1. the vehicle delay device is on, to avoid an excess of current when the car on burn-vehicle device. 2. it is necessary to have in order to start the occasion, to avoid multiple devices at the same time, the starting current is too large appliances that burn. Quantity:1Pc Note: Size for manual measurement, there may be a 0 to 2 cm error, belongs to the normal phenomenon. And due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you! Package includes(no retail package): 1Pc x Module
