Product description 2Pcs DC 12V Timer Relay Adjustable Signal Trigger Timing Timer Delay Turn Off Delay Timer Switch Automatic Start with Optocoupler DC 12V Adjustable Signal Trigger Timing Timer Delay Turn Off Delay Timer Switch Automatic Start Relay Module W/ Optocoupler

Working principle:This module is a delay module triggered by an external signal.

Specifically: 1)--to->2)--to->3)--to->4).

1) Supply power to the module (12v or 5V), and the relay will be closed immediately (at this time, the status of the module output terminal is: normally open and public conduction, normally closed and public disconnection)

2) The relay is disconnected after a delay of 0-25 seconds (the output status of the module at this time is: normally open and public disconnection, normally closed and public conduction)

3) Keep disconnecting until it is triggered by an external trigger signal, the relay is closed again

4) After successful triggering, the relay will be disconnected after a delay of 0-25 seconds. Note: If the trigger signal is always on, the module will be closed until the trigger signal disappears. open. (At this time, the relay returns to the state before triggering normally open and public disconnection, normally closed and public conduction).

In addition: (The trigger signal of this module can be provided by a separate power supply system and the power supply of the module may not be the same power supply system. At the same time, the trigger level can be a high-level pulse or a low-level pulse, which has strong versatility.)

Module features:

1. DC 12V Timer Relay Adjustable Signal Trigger Timing Timer Delay Turn Off Delay Timer Switch Automatic Start With Optocoupler

2. The working voltage of the module is 12V

3. The module can be controlled: 10A 250VAC (AC), 10A 30VDC (DC) or less load.

4. The time can be adjusted by the potentiometer. The default is 0-25 seconds. It takes longer. You can replace a larger capacitor or potentiometer by yourself,

5. Delay time formula: T=1.1RC. For example: capacitance 47uf resistance 500K T=1.1*500000*0.000047=25.85 seconds.

6. The power supply of the module is equipped with a diode to prevent reverse connection of the power supply, so friends can rest assured to connect.

7. The signal end of the module is designed with optocoupler isolation, which has strong anti-interference ability and can adapt to the application of high and low level control signals, and is suitable for industrial control.

8. The module can be triggered repeatedly (for example, if you set a delay of 10S, the trigger action occurs again within 10S of a certain trigger, and the 10S delay will be repeated when the action occurs again, that is, it will be triggered once after the ZUI within the undelayed period. Whichever is higher, delay 10S later, until the delay time reaches to complete the whole process of one trigger delay. After this delay is over, trigger again and delay again

9. No power consumption in standby (Almost power consumption in standby, zero current, greatly extending the life of the ca
