Ne555 Dc 12V Delay Relay Shield โล่สวิตช์รีเลย์ตั้งเวลา 0 To 10S โมดูลรีเลย์
Description:
1. Size: 6.8CM*2.1CM
2. Main chip: NE555
3. Working voltage: DC 12V
4. Features:
1. Turn on the power relay to delay the closing. Specifically: after supplying 12v power to the relay the relay will not immediately absorb and the status of the relay output terminal is: normally open and public disconnect normally closed and public conduct; after the delay 1-10s (adjustable) the relay At this time the state of the relay output terminal is: normally open and public conduction normally closed and public disconnection; as long as the module is continuously powered this state will always be maintained.
2. The delay time is adjustable (0～10 seconds)
4. Increasing the potentiometer can increase the delay time
5. Increasing the capacitor C1 can increase the delay time
6. With input power indicator
7. With relay pull-in indicator
8. It can control AC 220V/10A lower equipment. (Control equipment 2000W)
9. With relay freewheeling protection.
10. Delay time formula: T=1.1RC. For example: capacitance 100uf resistance 100K T=1.1*100000*0.0001=11 seconds
【Applications】
1. Delayed connection of on-board equipment to prevent excessive current from burning down on-board equipment when the car is on fire.
2. Where there is a need for sequential start prevent multiple devices from starting at the same time and the electric current is too large to burn the electrical appliances.
