Функции и совместимость

1. Connect the power supply and delay the closing of the relay (this module only has a delay closing function and does not have a delay disconnection function unless the power is cut off). Specifically, after being powered on, the relay will not immediately draw in and out. At this time, the output terminal of the relay is in the following states: normally open and disconnected from the common, normally closed and connected to the common; After a delay of 1-10 seconds (adjustable delay), the relay will draw and connect. At this time, the state of the relay output terminal is: normally open and connected to the common, normally closed and disconnected from the common; As long as the module is continuously powered on, this state (relay suction state) will remain. Test phenomenon: After power on, the red power indicator light will turn on. After a delay of 1-10 seconds, the relay will pull in and hear a “click” sound, and the blue relay pull in indicator light will turn on

2. The delay time is adjustable, ranging from 0 to 10 seconds

4. Adding a potentiometer can increase the delay time

5. Increasing capacitor C1 can increase the delay time

6. Equipped with an input power indicator light

7. Equipped with relay engagement indicator light

8. Can control equipment with AC voltage below 220V/10A. (Maximum control equipment 2000W)

9. Equipped with relay continuous current protection.

10. Delay time formula: T=1.1RC. For example: capacitor 100uf, resistor 100K T=1.1 * 100000 * 0.0001=11 seconds

Приложения

1, the delay-vehicle device is turned on, to prevent excessive current when the car ignition burn-vehicle device.

2, you need to have in order to start the occasion, to prevent multiple devices simultaneously starting current is too large burning appliances.
