ESP8266 ESP-01S Relay module, relay WIFI smart socket (with ESP-01S)Description:1. Suck in the power relay and disconnect within a fixed time of 1-10s. Specifically, after providing 12v power to the relay, the relay will not immediately absorb the sum. The output status of the relay is: normally open and normally open, normally closed and normally closed; after a delay of 1-10 seconds (adjustable), the relay is released. At this time, the status of the relay output terminal is: normally open and normally closed, normally closed and normally open; as long as the module continues to be energized, this state will always be maintained for a fixed time of 1-10s to absorb and release2. Adjustable delay time (0 10 seconds)4. Increasing the potentiometer will increase the delay time5. Increasing capacitor C1 can increase the delay time6. With input power indicator7. With a relay indicator light8. It can control AC 220V/10A equipment. (Maximum control equipment 2000W)9. With relay protection10. Delay time formula: T = 1.1rc. For example, the capacitance is 100uf and the resistance is 100K100 Percent Brand new high qualityModule working voltage: DC 5VRelay load capacity: 10A 250VAC 10A 125VAC 10A 30VDC 10A 28VDC Product size: 37.2 25.2mmContains: 2pcsNote:Manual measurement, with small error.
