Relay Module, Delay 0-10 Seconds 5V with Freewheel 2 Pieces NE555 2

Turn on the power relay to pull in and off at a fixed cycle of 1-10s. Specifically: after the relay is supplied with 12v power, the relay will not immediately sink. The state of the relay output is: normally open and common conduction, normally closed an Delay time is , (0~10 seconds) Incrse the potentiometer to incrse the delay time Ftures: 1. Turn on the power relay to pull in and off at a fixed cycle of 1-10s. Specifically: after the relay is supplied with 12v power, the relay will not immediately sink. The state of the relay output is: normally open and common conduction, normally closed and public disconnected; wait until the delay is 1-10s (can be adjusted), the relay Relsed, at this time, the state of the relay output is: normally open and common open, normally closed and common conduction; as as the module is continuously powered, this state will remain closed and relsed at a fixed cycle of 1-10s. 2. Delay time is , (0~10 seconds). 3. Incrse the potentiometer to incrse the delay time. 4. Incrse the capacitance C1 to incrse the delay time. 5. With input power indicator. 6. With relay pull-in indicator. 7. Can control AC 220V/10A equipment. (Maximum control device 2000W). 8. With relay freewheeling . 9. Delay time : T equal 1.1RC. For example: Capacitance 100uf resistance 100K T equal 1.1 * 100000 * 0.0001 equal 11 seconds. Specification: Main chip: NE555 Working voltage: 5 volts Size: approx. 6 * 1.7cm / 2.4 * 0.7in Weight: approx. 34g Package list: 2 * Relay Module
