Vender [seenuewday] NE555 Delay Relay Module Timer Switch Adjustable Module Time DC 5V/12V Relay CO al mejor precio

Feature: 100% Brand and high quality. Size: 6.8CM*2.1CM Main chip: NE555 Working voltage: DC 12 volts Features: 1. Turn on the power relay to delay pull-in. Specifically: after supplying 12v power to the relay, the relay will not absorb immediately, and the status of the relay output terminal is: normally open and public disconnection, normally closed and public conduction; after a delay of 1-10s (can be adjusted), the relay At this time, the state of the relay output terminal is: normally open and common conduction, normally closed and common disconnection; as long as the module is not powered, this state will always be maintained. 2. The delay time is adjustable, (0~10 seconds) 4. Adding a 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 light 8. It can control AC 220V/10A equipment. (Maximum control device 2000W) 9. With relay freewheeling protection. 10. Delay time formula: T=1.1RC. For example: Capacitor 100uf Resistor 100K T=1.1*100000*0.0001=11 seconds Applications The on-board equipment is switched on with a delay to prevent the vehicle from being burned by excessive current when the car is on fire. When it is necessary to start sequentially, prevent multiple devices from starting at the same time with excessive current and burn out the electrical appliances.
